Scientists report important data in stem cell debate

IH's National Human Genome Research Institute, and Dr. Michael Brownstein, a scientist at NIH's National Institute of Mental Health. "I would have never been able to do this study if I had been in another type of setting," said Tran, highlighting the unique multidisciplinary environment at NIH that allows more complex studies to be undertaken.

Once the assay was up and running, the scientists discovered that all five women had cheek cells that contained both X and Y chromosomes. The range was from 0.8 percent in one woman to 12.7 percent in another. Because some of the women had sons, the scientists performed an additional DNA analysis that ruled out the possibility of the cells originating from their male offspring. The cells also tested positive for cytokeratin.

Interestingly, of the 9,700 cells that were examined in the study, only two showed signs of possible fusion. In the previous reports of cell fusion from celll culture studies, the rate was also extremely low, ranging from one every 100,000 to one million adult stem cells.

While Tran said this paper does not provide the definitive answer to the transdifferentiation debate, it does offer a higher level of evidence. "I hadn't studied stem cells previously," said Tran, who is employing tissue engineering techniques to develop an artificial salivary gland. "But I saw an opportunity to help forward the field with a model that perhaps some had overlooked. I think these data will be helpful to many."
