Sea Anemone’s Stem Cells May Hold Key to Immortality

The top image shows fluorescently labeled cells in the spinal cord of a zebrafish recovering one week after an injury, and the bottom image shows recovery four weeks after an injury. Researchers at Washington University School of Medicine in St. Louis describe the dramatic changes within nerve cells that make regeneration possible. Such findings could inspire the development of new therapies for spinal cord injuries in people.
