Graphene & electricity to change stem cells for nerve regrowth

Researchers looking for ways to regenerate nerves can have a hard time obtaining key tools of their trade.

Schwann cells are an example. They form sheaths around axons, the tail-like parts of nerve cells that carry electrical impulses. They promote regeneration of those axons. And they secrete substances that promote the health of nerve cells.

In other words, they’re very useful to researchers hoping to regenerate nerve cells, specifically peripheral nerve cells, those cells outside the brain and spinal cord.

But Schwann cells are hard to come by in useful numbers.

So researchers have been taking readily available and noncontroversial mesenchymal stem cells

Dental stem cells to regrow and repair teeth

In a first, scientists, including one of Indian-origin, have used light to coax stem cells to regrow parts of teeth.

The study, led by David Mooney, a Core Faculty member at the Wyss Institute for Biologically Inspired Engineering at Harvard, is the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue.

The researchers used a low-power laser to trigger human dental stem cells to form dentin, the hard tissue that is similar to bone and makes up the bulk of teeth (…)

A number of biologically active molecules, such as regulatory proteins
