Zebrafish melanocytes cause diseases similar to those in people when they don’t work properly. Studying how they regenerate after injury could lead to new treatments for hair color loss and vitiligo.

Tissue engineering and regenerative medicine is based on three key requirements working together: signals from body tissues and organs, responding stem cells, and scaffolds.

When kids get injured their skin heals fast, but usually with nasty-looking scars. Now scientists studying the genes of old mice have figured out how they regenerate skin and block scars.
It is a sad fact that old age brings diseases. Many may not be life-threatening, but they make life less fun. One such condition is sarcopenia, which causes the loss of muscle mass and strength, and it…
