Credit: UT Southwestern Medical Center Using genetic engineering, researchers at UT Southwestern and Indiana University have reprogrammed scar-forming cells in mouse spinal cords to create new nerve cells, spurring recovery after spinal cord injury. The findings, published online today in Cell Stem Cell, could offer hope for the hundreds of thousands of people worldwide who suffer a spinal cord injury each year. Cells in some body tissues proliferate after injury, replacing dead or damaged cells as part of healing. However, explains study leader Chun-Li Zhang, Ph.D., professor of molecular b...

Credit: IU School of Medicine Researchers at Indiana University School of Medicine have successfully reprogrammed a glial cell type in the central nervous system into new neurons to promote recovery after spinal cord injury--revealing an untapped potential to leverage the cell for regenerative medicine. The group of investigators published their findings March 5 in Cell Stem Cell. This is the first time scientists have reported modifying a NG2 glia--a type of supporting cell in the central nervous system--into functional neurons after spinal cord injury, said Wei Wu, PhD, research associate ...

Cao Cao and his seventy-two decoy tombs – so which one is real? Cao Cao (155 to 220 AD) was a warlord and the penultimate Chancellor of the Eastern Han dynasty who rose to great power in the final years of the dynasty.
