So what this article is saying they are trying to get ordinary cells found on the body to revert back to stem cells without having to use viruses which remain in the stem cell. This is because viruses can increase the risk of the stem cells developing tumors and such. Apparently this parasitic element can infiltrate the normal skins cells, turn it into a stem cell and then exit the cell without leaving anything behind that can increase the risk of cancer developing....
Wow this is a pretty cool idea! I remember reading about some boy who had some stem cell implanted into his brain that later turned into tumor cells. Hopefully this technique will resolve that problem with stem cells.
