Adult Stem Cells and Regeneration

In this Howard Hughes Medical Institute video, Nadia Rosenthal, senior scientist at the European Molecular Biology Laboratory, discusses newly emerging discoveries that may indicate just how flexible adult stem cells may be in their ability to produce divergent cells in the body. Unlike animals such as sea stars, humans have a more limited ability to regenerate parts of the body but newly emerging research may help solve the evolutionary puzzle of why mammals have such limited powers of regeneration.
