(Medical Xpress)—Researchers from the US and Japan have shown that an aggressive type of brain tumor can arise from normal cells in the central nervous system such as neurons. The cells revert to an earlier, undifferentiated ...
Among the many hurdles to be cleared before human embryonic stem cells can achieve their therapeutic potential is determining whether or not transplanted cells can functionally integrate into target organs or tissues.

A team of medical researchers at the National Children's Medical Center, Children's Hospital, Fudan University, in China, has developed a technique to freeze and thaw brain tissue without causing damage.
The brain resembles a road network: Like country roads, small connections link neighboring nerve cells, while, like highways, thick nerve bundles connect different regions of the brain. These thick, heavily used nerve bundles, ...
