The strife in medicine today is to push science to a level advanced enough to produce replacement bones, tissues, skin and other organs from various types of stem cells. While this is definitely a possibility, work in this field is hindered by the fact that growing a kidney in a bioreactor, for instance, is kind of p... |

A new research has shown that the cells that remain in the limb stumps of salamanders do not, in fact, revert to their most basic state, the embryonic one. Rather, they “downgrade” to a certain point, but that point is far above the embryonic state. Thus, they can recover a lot faster, and contribute to g... |
