Cells that are about to die send a signal to an executioner protein, but sometimes, those cells can fight back and regenerate ...

When tissue is severely damaged, surviving cells can respond in a concentrated burst of biological repair known as ...

Plant regeneration relies on a delicate balance between stem cell renewal and differentiation, yet the evolutionary origin ...

You might feel the same every day, but biologically, you never are. Beneath the surface, your body is constantly rebuilding ...

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 ...

As muscles age, their cells lose the ability to regenerate and heal after injury. Now, Cornell University researchers have created the most comprehensive portrait to date of how that change, in mice, ...

Some parts of our bodies bounce back from injury in fairly short order. The outer protective layer of the eye—called the ...

A diet rich in the amino acid cysteine may have rejuvenating effects in the small intestine, according to a new study from MIT. This amino acid, the researchers discovered, can turn on an immune ...

A stem cell therapy for stroke restored neuron function and revealed how transplanted cells navigate the nervous system.

Tooth loss and bone degeneration are problems that modern medicine still struggles to fix. Data from the National Bone Health Policy Institute shows that 10 million Americans over the age of 50 have ...

Scientists identify specific genes involved in zebrafish sensory hair cell regrowth, providing new insights that could inform future research into hearing loss treatments. While humans can regularly ...
