When it comes to regrowing tails, neural stem cells are the key

Cut off a salamander's tail and, in a few weeks, a near-perfect replacement grows. Do the same to a lizard and a new tail will regrow, but it won't be the same as the original. By comparing tail regeneration between the two ...

Better tissue healing with disappearing hydrogels

When stem cells are used to regenerate bone tissue, many wind up migrating away from the repair site, which disrupts the healing process. But a technique employed by a University of Rochester research team keeps the stem ...

Salamanders, regenerative wonders, heal like mammals, people

The salamander is a superhero of regeneration, able to replace lost limbs, damaged lungs, sliced spinal cord -- even bits of lopped-off brain. But it turns out that remarkable ability isn't so mysterious after all -- suggesting ...

UCSF team closer to creating safe embryonic-like stem cells

A team of UCSF researchers has for the first time used tiny molecules called microRNAs to help turn adult mouse cells back to their embryonic state. These reprogrammed cells are pluripotent, meaning that, like embryonic stem ...

Dental stem cells can generate milk-producing cells

Stem cells of the teeth can contribute to the regeneration of non-dental organs, namely mammary glands. According to a new study from researchers at the University of Zurich, dental epithelial stem cells from mice can generate ...
