Like the seeds of a forest, a few cells in embryos eventually sprout into an ecosystem of brain cells. Neurons get the most recognition for their computing power. But a host of other cells provides ...

Some parts of our bodies bounce back from injury in fairly short order. The outer protective layer of the eye—called the cornea—can heal from minor scratches within a single day. The brain is not one ...

Neurons from grafted stem cells contain intrinsic codes for navigating and forming connections, which may improve cell therapy for a brain short-circuited by stroke. Some parts of our bodies bounce ...
