Rather, the experiment was a proof of concept that stem cells can generate any cell in the body - not only the dozens of tissues that make up the human body but also those egg and sperm cells that may give rise to altogether new bodies. "Other cell types don't generate the next generation," says Nayernia, a professor of stem-cell biology at Newcastle...
...will react once inside a patient's body. The most pressing question remains whether iPS cells - or the nerves, muscles or any of the 200 other types of tissues potentially generated from them - would act the same way as human embryonic stem cells, which were not created in a petri dish. "We don't know if iPS cells can do everything that normal human embryonic stem cells can do," says Lanza. "There are certainly a lot of questions we still have to answer." But having a population of stem cells that are safe for human use is an important step...
