Planarians are a striking model for studying regeneration owing to their extraordinary capacity to reform entire body structures from small tissue fragments. This ability is mediated primarily by ...

A new study reported in Nature has determined that the amino acid cysteine could promote regeneration among cells in the small intestine. The work showed that cysteine can activate an immune signaling ...

While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other parts of the body. For example, when the tiny sensory hair cells in our inner ...
