Gel hope for brain injury repair

An injectable hydrogel could aid recovery from brain injury by helping stimulate tissue growth at the site of the wound, researchers say.
Research on rats suggests the gel, made from synthetic and natural sources, may spur growth of stem cells in the brain (…)

Researchers say the advantage of the new gel, which is injected into the injury in liquid form, is that it can be loaded with different chemicals to stimulate various biological processes.

First, Dr Zhang used it to help re-establish a full blood supply at the site of a brain injury in rats, potentially providing a much more friendly environment for donor cells to thrive.
Then, in follow-up work, she loaded it with immature human stem cells and the chemicals they need to develop into fully fledged adult brain cells (…)
