Resting brain stem cells hardly differ from normal astrocytes, which support the nerve cells in the brain. How can almost identical cells perform such different functions? The key lies in the ...

A pioneering clinical trial is exploring whether lab-engineered stem cells can restore dopamine production in people with Parkinson’s disease.

Researchers in Japan have developed a form of stem cell therapy that "reverses" paralysis. Though the treatment has only seen a 50% success rate so far, two of the four people who received it have ...

Parvalbumin (PV) interneurons act as the brain’s rhythm keepers. By regulating local circuit activity and maintaining excitation–inhibition balance, they help stabilize cortical network function. When ...

A mature cell of one type can be turned into a mature cell of another type without the cell having to pass through an earlier stage of development. This is called direct reprogramming, a reliable but ...

In a first-of-its-kind clinical trial, UCLA scientists have shown it’s possible to reprogram a patient’s blood-forming stem cells to generate a continuous supply of functional T cells, the immune ...

I attended the Global Wellness Summit in Dubai (my 13th consecutive, I think), which focused on transformative technologies that are making wellness for an extended lifetime more attainable. The use ...

Cartilage is the body’s most stubborn tissue. Once it wears away, it’s usually gone for good. This biological dead-end is the ...
