Stem Cell Discovery Could Help Regrow Fingers

We will all be Wolverine soon

Mammals can regenerate the very tips of their fingers and toes after amputation, and now new research shows how stem cells in the nail play a role in that process.

A study in mice, detailed online today (June 12) in the journal Nature, reveals the chemical signal that triggers stem cells to develop into new nail tissue, and also attracts nerves that promote nail and bone regeneration.
