DNA 'tattoos' link adult, daughter stem cells in planarians
Unlike some parents, adult stem cells don't seem to mind when their daughters get a tattoo. In fact, they're willing to pass them along. Using the molecular equivalent of a tattoo on DNA that adult stem cells (ASC) pass to ...

Heads or tails? Scientists identify gene that regulates polarity in regenerating flatworms
When cut, a planarian flatworm can use a population of stem cells called neoblasts to regenerate new heads, new tails or even entire new organisms from a tiny fragment of its body. Mechanisms have been sought to explain this ...
