Got pain? NASA TECHNOLOGY MAY STOP IT.

 Of more than 10,000 research papers and 2000 plus double blind studies on PEMF therapy; none was more thorough and conclusive as the 4 year NASA study lead by Dr. Thomas Goodwin, PhD, on the ability of PEMF to improve the growth and repair of tissues in mammals.
This study is a landmark in proving the efficacy of PEMF therapy on human cells for healing, growth and regeneration, specifically the stimulation of neural stem cells. This research summary is of necessity somewhat complex, because of the complexity of the science. It is likely to be mostly of interest to those who have a scientific or engineering background. Nonetheless, this summary serves to highlight the impressive and in-depth scientific and engineering background that served as the basis for using PEMF therapy.

Abstract
The present investigation details the development of model systems for growing two- and three- dimensional human neural progenitor cells within a culture medium facilitated by a time-varying electromagnetic field (TVEMF). The cells and culture medium are contained within a two- or three-dimensional culture vessel, and the electromagnetic field is emitted from an electrode or coil. These studies further provide methods to promote neural tissue regeneration by means of culturing the neural cells in either configuration. Grown in two dimensions, neuronal cells extended longitudinally, forming tissue strands extending axially along and within electrodes comprising electrically conductive channels or guides through which a time-varying electrical current was conducted. In the three-dimensional aspect, exposure to TVEMF resulted in the development of three-dimensional aggregates, which emulated organized neural tissues. In both
experimental configurations, the proliferation rate of the TVEMF cells was 2.5 to 4.0 times the rate of the non-waveform cells. Each of the experimental embodiments resulted in similar molecular genetic changes regarding the growth potential of the tissues as measured by gene chip analyses, which measured more than 10,000human genes simultaneously.
Background
Since the 1980s, many methods have been employed in an attempt to accomplish the regeneration of neuronal tissues. Hinkle et al. (1980) detailed the directional growth of frog neurons in an electric field applied by inducing direct DC voltage. Similarly, researchers both nationally and internationally have employed DC electric fields externally and internally as implants to stimulate the direct regeneration of nerve cells in a variety of animal tissues (Borgens et al. 1981,1986, 1986a, 1990, 1997).
These studies have met with limited success, but have shown the potential efficacy of using the inherent characteristics of neural cells to achieve their regeneration. All of these studies incorporate the inclusion of electrodes in direct contact with the tissue of interest.
Other studies have shown that electrically charged polymeric substrates may have value in the stimulation of the regenerative process (Valentini et al., 1992; Makohliso et al., 1992). Additionally, Borgens et al. (1994) substantiates the inference that low-level electric fields and physiological voltage gradients are of importance. However, continuing investigation in these areas has indicated the possibility of a missing component to complete the valuable work of
1

previous investigations. The missing component may well be the addition of a magnetic element.
Combining the electric and magnetic elements would seem logical, but to date may not have been employed due to traditional purist approaches to experimentation. The current studies are a composite of physiology and electromagnetic bioengineering, which relate generally to the fields of biophysics, tissue regeneration, tissue culture, and neurobiology. The present investigation relates to the use of a time-varying electromagnetic field for potentiation of the growth of mammalian cells and tissues. The preferred protocol uses two-dimensional conducting plate electrodes and may be applied to conventional two-dimensional tissue cultures or to three- dimensional tissue cultures. One may achieve three-dimensional cultures either by exposure to actual microgravity or by using rotating wall vessel (RWV) technology, which simulates some of the physical conditions of microgravity (Goodwin et al., 1993~)T. he time-varying electromagnetic field is achieved in the vicinity of the electrode by passing a time-varying current pulse with modulated signal through the electrode.
Growth of a variety of both normal and neoplastic mammalian tissues in both mono-culture and co-culture has been established in both batch-fed and perfused RWVs (Schwarz et al., 1991a,
1991b), and in conventional plate or flask-based culture systems. In some applications, growth of three-dimensional tissues in these culture systems has been facilitated by support of a solid matrix of biocompatible polymers and microcarriers. In the case of spheroidal growth, three- dimensional structure has been achieved without matrix support (Goodwin et al., 1992, 1993a,
1993b, 1997). The NASA RWV tissue culture technologies have extended this three- dimensional capacity for a number of tissues and have allowed the tissue to express different genesandbiomolecules. Neuronaltissuehasbeenlargelyrefractory,intermsofcontrolled growth induction and three-dimensional organization, under conventional culture conditions. Actual microgravity, and to a lesser extent, rotationally simulated microgravity, have permitted some enhanced nerve growth (Lelkes and Unsworth, 1997). Previous attempts to electrically stimulate growth have used static electric fields, static magnetic fields, and the direct passage of current through the culture medium, but not the induction of an AC time-varying electromagnetic field in the culture region.
Neuronal tissue comprises elongated nerve cells composed of elongated axons, dendrites, and nuclear areas. Axons and dendrites are chiefly responsible for transmission of neural signals over distance. Longitudinal cell orientation is critical for proper tissue formation and function. The nucleus plays the typical role of directing nucleic acid synthesis for the control of cellular metabolic function, including growth. In vivo, the neuronal tissue is invariably spatially associated with a system of feeder, or glial, cells. This three-dimensional spatial arrangement has not been reproduced by conventional in vitro culture.
2

Investigators (Borgens et al., Valentini et al., and others) have used static electric fields in an attempt to enhance nerve growth in culture with some success to either alter embryonic development or achieve isolated nerve axon directional growth, but have not yet achieved actual control mechanisms for potentiation of growth or genetic activity causing growth. Mechanical devices intended to help grow and orient three-dimensional mammalian neuronal tissue are currently available. Fukuda et al. used zones formed between stainless steel shaving blades to orient neuronal cells or axons. Additionally, electrodes charged with electrical potential were employed to enhance axon response. Aebischer described an electrically charged, implantable tubular membrane for use in regenerating severed nerves within the human body.
None of these devices uses channels of cell-attractive material, nor do they apply a time-varying electromagnetic field, a static electrical, or a static magnetic field. Additionally, no use is made of simulated or actual microgravity techniques for pure neuronal or mixed neuronal and feeder cell cultures. Incorporation of an electromagnetic stimulus in conjunction with growing three- dimensional mammalian neuronal tissue in the proximity of, or directly upon the surface of, a current-carrying electrode (which may be bioattractive and directly adherent to the cells) is expected to enhance the proliferative response. Furthermore, the use of a time-varying current to induce a corresponding time-varying electromagnetic field in the vicinity of the growing culture to potentiate or spatially direct cell growth is not part of the prior art.
Materials and Methods
Cells
Normal human neuronal progenitor cells (NHNP) were pooled from three donors to diminish donor-to-donor variations in response. As controls, NHNP were grown in conventional tissue
culture following standard cell culturing procedures in tissue culture flasks obtained through Clonetics Corporation, San Diego, California.
Cell Culture Protocols
For two-dimensional culture, GTSF-2 medium with 10% FBS, Ciprofloxacin and Fungizone was used to culture the cells (Goodwin et al., 1993a). 1 X PBS, Collagenase, DNase and trypsin were purchased from Clonetics San Diego, California, and used Corning T-75 flasks (Corning Inc., Corning, New York) for initial cell culture to obtain the appropriate number of cells for each experiment. Briefly, cells to be cultured were enzymatically dissociated with the referenced reagents from T-flasks, washed once with PBS-CMF and assayed for viability by trypan dye exclusion (GIBCO, Grand Island, New York). Cells were grown on 100-mmpetri dishes (tissue culture treated to prevent adherence) or grown on the actual electrodes inside the petri dishes. Electrodes were made of platinum and stainless steel. Cell cultures were maintained in a humidified Forma CO2 incubator (Forma, Inc.) at 37°C at a C02 concentration of 6%.
3

For three-dimensional culture, NHNP cells were prepared as described above and an RWV was sequentially inoculated with 5 mg/ml Cytodex-3 type 1 collagen-coated microcarriers (Pharmacia) and freshly digested NHNP cells, yielding a cell density of 2.5.x lo5 cells/ml in a55-ml vessel. Tissues were cultured for 17 to 21 days or until 3- to 5-mm diameter tissue masses formed.
Generator
A waveform (TVEMF) generator of original design and capability was developed and used to generate the waveform in a strength of 1-6 mA (AC) square wave, 10 Hz variable duty cycle, which was pulse-width modulated (Goodwin et al. patent cases MSC 22633-1; US Patent, 6,485,963, B1 and MSC 22633-2 Notice to Issue). NHNP cells were subjected to these extremely low-level magnetic fields (ELF waves) (-10 - 200 mGauss), which are far less than the field strength of the Earth. Figure 1 illustrates the experimental arrangements for two- dimensional cell cultures.

FIGURE 2. The NHNP cells produced a whitish fingerprint on each of the electrodes under TVEMF.
Cells were incubated for 2 days. The second day after cell inoculation is considered day 0 of the experiment protocol. At day 0, each dish was given 15 ml of media and waveform was applied to the electrodes. Cells were fed with 15 ml of media at day 3 and with 13 ml every three days thereafter at day 6 , 9 , and 12. At days 14 and 17, the cells were fed again with 15 ml of media. At days 17 to 21, the cells were incubated for 10 minutes in a CollagenaseDNase cocktail, then trypsin was directly applied to the cocktail and the cells were further incubated for 3 more minutes. Before the complete media was added to deactivate the trypsin, the cocktail mix was pipetted up and down several times. The cells were washed twice with 1 X PBS, reapplied with the media, and placed on ice. The cells were observed under a dissecting microscope, counted, and assessed for viability.
An identical protocol was followed in similar experiments with the exception that, instead of the electrode being placed within the petri dishes, in media, it was attached to the underside of the TVEMF treated dishes, so that the cells had no direct contact with the metal surface.
Two-Dimensional Experimental Protocols
Initially, a metal electrode was placed inside a petri dish and centered. NHNP were seeded at 2.5 x 105 cells in 0.7 ml of media and carefully dropped on the electrode in a concentrated

Three-Dimensional (RWV) Experimental Protocol
Three-dimensional neural cells and tissues were cultured by the method described above, except that the TVEMF RWV was modified to incorporate an electromagnetic coil. The coil was wrapped around the core of the vessel so it emitted the same electromagnetic field strength as in the two-dimensional configuration. All other conditions were identical to the two-dimensional experimental conditions.
Analytical Methods
Cell Metabolic Parameters
The following metabolic parameters were monitored on a daily basis during the culture of the RWV model: pH, dissolved 0 2 , dissolved C02, glucose concentration, cell viability, and LDH (lactate dehydrogenase). Dissolved 02, C02, pH, and glucose are routinely measured in our laboratories (Goodwin et al., 1992, 1993b; Jessup et al., 1994; Scharz et al., 1992). At 24-hour intervals, pH, C02, and 0 2 were determined on a Corning 238-model clinical blood gas analyzer (Corning,Corning,NewYork). TheglucoseconcentrationwasdeterminedbyaBeckman2model clinical glucose analyzer (Beckman Instruments, Inc., Fullerton, California). Samples for determination of LDH levels were collected each 24-hour period. LDH analyses were performed on a clinical Kodak Biolyzer (Kodak, Inc., New Haven, Connecticut) using dry chemistry technique.
Light Microscopy
Two-dimensional samples of each experiment were photographed by a Nikon T330 microscope equipped with advanced Hoffman Modulation optics (Nikon Inc., New York, New York).
Scanning Electron Microscopy
Samples for scanning electron microscopy were harvested every 48 hours of culture and were washed once in PBS-CMF, fixed in a solution containing 3% glutaraldehyde, 2% paraformaldehyde in 0.1M cacodylatebuffer at pH 7.4, processed by RMC, Inc., and scanned at 10kV.
Genetic Discovery Array
Samples of human NHNP cells grown in conventional flask culture were trypsinized and placed into petri dishes in a 55-ml RWV. After 17-21 days of culture on 5 mg/ml cytodex-3 beads, cells were washed once with ice-cold phosphate buffered saline. The cells were lysed and mRNA selected with biotinylated oligo (dT) then separated with streptavidin paramagnetic particles (Poly A Ttract System 1000, Promega Madison, WI). 32P-labeled cDNA probes were generated by reverse transcription with 32P dCTP. The cDNA probes were hybridized to identical gene discovery array filters (Incyte Genome Systems Inc., St. Louis, Missouri). The gene discovery
6

array filters contain over 12,000 unique human genes from the I.M.A.G.E. Consortium (LLNL)l cDNA Libraries, which are robotically arrayed on each of a pair of filter membranes. Gene expression were then detected by phosphor imaging and analyzed using the Gene Discovery Software (Incyte Genome Systems Inc., St. Louis, Missouri).
Statistical Analysis
All experimental and control groups were analyzed in triplicate or quadruplicate, depending on the availability of materials. These were averaged for determination of mean and standard error. Frequencies in phenotypic analysis were compared by chi-square. Proliferation as assessed by 3H-TdR uptake was compared by analysis of variance for multiple groups, using the Student’s t-test for paired groups (Zar, 1974).

After the application of the TVEMF, the cells preferentially aligned, while cells without waveformexposureshowedanormalrandompattern. Cellsindirectcontactwiththeelectrode remained stimulated up to 72 hours after the TVEMF was removed (Table 3), while those not in direct contact with the electrode continued to experience an accelerated and long-term stimulation in growth pattern even 168 hours after the TVEMF was removed (Table 4). Viability was also higher in the cells exposed to the waveform (Table 4). In each case, cell growth returned to normal rates without further TVEMF stimulation.
To examine the accelerated growth pattern, called the Corona Effect, after treatment with TVEMF, the same treatment was applied to the cells without harvesting. Several petri dishes, eachfromtheTVEMFgroupandnon-waveformgroups,werechosenrandomly. Cellsstill attached in sheet form were lifted off of the electrodes carefully and placed in new petri dishes with medium, and then photograph 24 hours later (Figs. 4-6).

Three-Dimensional Experiments
The ability to influence and, to some degree, control, the growth patterns of NHNP cells in the two-dimensional aspect is a great investigational tool. The question that emanated from this result was, did we have the ability to construct a three-dimensional model and have it emulate the same genetic influence of the TVEMF as shown in Figures 4 and 5? To answer this question, we turned to a new technology called RWV.

Rotating-Wall Vessel Background
The RWV was created at the Johnson Space Center in 1985 to address the problems associated with attempting to simulate microgravity conditions in an Earth-bound lab. It was designed to maximize the conditions of free fall while allowing continuous cell culturing over prolonged periods of time. This instrument uses a cylindrical tube with suspended particles that is rotated inline with the horizontal axis. The particles move in conjunction with the fluid and the wall of the vessel, the effects of gravity are randomized, modeling some aspects of microgravity, while reducing to a minimum shear and turbulence (Dedolph and Dipert, 1971; Cogoli and Gmiinder, 1991; Schwarz et al., 1992; Prewett et al., 1993, Goodwin et al., 1993).
Several fluid dynamic operating principles define the RWV. First, it is composed of a solid body rotation about a horizontal axis characterized by (a) co-location of particles of different sedimentation rates, (b) extremely low fluid shear stress and turbulence, and (c) three- dimensional spatial freedom. Second, oxygenation is by active or passive diffusion so that only dissolved gasses are present in the reactor chamber. There are no gas bubbles and no gadfluid interface (Wolf and Schwarz, 1991; Schwarz et al., 1992; Goodwin et al., 1993).
Rotating- Wall Vessel Experimental Data
We modified an RWV by adding an electromagnetic field coil to allow observation of TVEMF influence on NHNP cells in three-dimensional aspect. Using the RWV, we replicated our preliminary results from the two-dimensional studies several times, and have analyzed the gene expression using gene arrays. We monitored cell proliferation, orientation, morphology, glucose metabolism, and pH (Figs. 7-1 1). Our results show a stable, reliable model to study the control of high-level cellular processes by application of low-amplitude, time-varying micromagnetic fields.
Figures 7 to 11 show that metabolic parameters evidenced little or no differences between TVEMF and control three-dimensional culture. This would indicate that, although cellular growth was enhanced and more directed, additional cellular energy was not required to accomplish this effect. The RWV-grown tissues also emulated the same basic genetic response as the two-dimensional tissues at similar fields strengths.
This study focused on the use of NHNP cells because of their importance in human nervous system development and maintenance. However, we have developed two-dimensional and now three-dimensional bioreactors that can potentially accommodate other cell lines. Initial results with the NHNP cells were quite startling, using extremely low-level magnetic fields (-10 -
200 mGauss), below the magnetic field strength of the Earth itself (approximately 500 mGauss). We found the low-amplitude, rapidly time-varying magnetic fields exerted a very potent effect on the proliferation, morphology, and gene expression of the cells in culture, both in standard 2-dimensional culture plates (Fig 12) as well as cells organized into 3-dimensional tissue clusters (Fig 8) in the RWV.

Gene Array
NHNP cells were exposed to TVEMF and non-waveform growth conditions for 17-21 days. Upon completion of the exposure period, cells were harvested via trypsinization and poly-RNA was prepared from the respective groups of cells. RNA samples were quick frozen and subjected to the Gene Discovery Array from the I.M.A.G.E. Consortium (LLNL) 1 cDNA analysis as described above. The tables below show the results of a survey of the response of over 10,000 human genes. The results are divided into two categories and shown in Tables 5 and 6. Table 5 shows those genes that were down-regulated or suppressed by the TVEMF and Table 6 shows those up-regulated or enhanced in activity by the TVEMF.
Analysis of the data indicates a significant down-regulation of about 175 maturation and regulatory genes and up-regulation of about 150 genes associated with growth and cellular proliferation. The down-regulated genes are normally associated with the differentiated or non- growth profile of normal cells. Table 5 lists the down-regulated genes in descending order. The up-regulated genes are in the main associated with growth and cellular proliferation. Table 6 lists the up-regulated genes in ascending order.

Before this study, neither two- nor three-dimensional growth of neural cells had been achieved with the positive outcome of enhanced growth and apparent gene regulatory control. The genes in Table 5 were down-regulated by between -1.4 to -2.7 logs. The genes in Table 6 were up- regulated by between 1.7 to 8.4 logs. This demonstrates that the results presented are in no manner marginal.

DISCUSSIOANND CONCLUSIONS
The ability to use TVEMF to control the proliferative rate, directional attitude, and molecular genetic expression of normal human neural progenitor cells has been demonstrated. The procedure is applicable to, but not limited to, the control of NHNP cells in both two-dimensional and three-dimensional culture. As presented in the molecular genetic data shown in Tables 5 and6 , many of the genetic responses in both up-regulated and down-regulated genes are maturation and growth regulatory in nature. These genes are also primarily involved in the embryogenic process. Therefore it is reasonable to conclude that control over the embryogenic development process may be achieved via the presently demonstrated methodology.
As shown in Table 6 , specific genes such as human germline oligomeric matrix protein, prostaglandin endoperoxide synthase 2, early growth response protein 1, and insulin-like growth factor binding protein 3 precursor are highly up-regulated. Table 5 shows Keratin Type IIcytoskelatal7, mytotic kinesin like protein 1, transcription factor 6 like 1, mytotic feedback

control protein, and cellular retinoic acid binding protein are down-regulated. Each of these two sets is only an example from the approximately 320 genes changes expressed as a consequence of exposure to TVEMF.
There is significant precedent in the literature for the results reported above. Kepler et al. (1990) reported the effects of the neurons with oscillatory properties on the composite of neural networks. This work illustrates the likelihood that a pulse width modulated system might bring on specific responses in neural tissues. As previously discussed, Valentini et al. (1993) demonstrated the ability to enhance the outgrowth of neural fibers on materials that possess a weak electric charge. This would indicate that intense electric fields are not necessarily an essential component of this process, and that a weak and persistent stimulus might yield a measurable effect.
Additional evidence of the effects of magnetic fields exists in the work of Sandyk et al. (1992a). This communication details dramatic improvement of a patient with progressive degenerative multiple sclerosis. Briefly, the patient showed considerable improvement when subjected to treatment at a frequency of 2-7 Hz and an intensity of the magnetic field of 7.5 pic0 Tesla. These parameters marginally parallel those of this report. In a similar fashion, Sandyk et al. (1992b) reported significant improvement in patents treated with the same field strength and intensity.
The ability to suppress or stimulate the growth of non-excitable cells has been reported in mouse lymphoma cells by Lyte et al. (1991). A narrow range of electric field was found to be effective at one end to stimulate and at the other to inhibit the growth of these cells. These data might suggest cellular receptors in all cells. To sustain this notion, Briistle et al. (1996) reported the potential to use neural progenitors for recapitulation of neural tissues. As would be expected, this would require genetic control at the embryonic level. We believe this study indicates our ability to trigger these parametric events.
As is clearly demonstrated in the human body, the bioelectric, biochemical process of electrical nerve stimulation is a documented reality. The present investigation demonstrates that a similar phenomenon can be potentiated in a synthetic atmosphere, Le., two-dimensionally or in rotating wall cell culture vessels. One may use this electrical potentiation for a number of purposes, including developing tissues for transplantation, repairing traumatized tissues, and moderating some neurodegenerative diseases and perhaps controlling the degeneration of tissue as might be effected in a bioelectric stasis field.

13. ABSTRACT (Maximum 200 words)
The present investigation details the development of model systems for growing two and three-dimensional human neural progenitor cells within a culture medium facilitated by a time-varying electromagnetic field (TVEMF). The cells and culture medium are contained within a two or three-dimensional culture vessel, and the electromagnetic field is emitted from an electrode or coil. These studies further provide methods to promote neural tissue regeneration by means of culturing the neural cells in either configuration. Grown in two-dimensions, neuronal cells extended longitudinally forming tissue strands extending axially along and within electrodes comprising electrically conductive channels or guides through which a time-varying electrical current was conducted. In the three-dimensional aspect exposure to TVEMF resulted in the development of three-dimensional aggregates, which emulated organized neural tissues. In both experimental configurations, the proliferation rate of the TVEMF cells was 2.5 to 4.0 times the rate of the non-waveform cells. Each of the experimental embodiments resulted in similar molecular genetic changes regarding the growth potential of the tissues as measured by gene chip analyses, which measured more than 10,000 human genes simultaneously
