Some parts of the body can recover from injury fairly rapidly. The cornea, for example, can heal from minor scratches within a single day. The human brain, however, is not one of these fast-healing ...

Researchers have used human neural stem cells to 3D print functional brain tissue that mimics the architecture of the cerebral cortex, the brain’s outermost layer. The breakthrough technique has the ...

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 ...

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 ...
