A team of stem cell researchers, led by Mick Bhatia, director of the McMaster Stem Cell and Cancer Research Institute, have discovered that they can convert adult human blood cells into adult sensory neurons. In other words, they developed a way to take blood samples and turn them into central nervous system and peripheral nervous system neurons. The central nervous system (CNS) is the part of the nervous system consisting of the brain and spinal cord. It integrates information it receives from, and coordinates and influences the activity of, all parts of the body and it contains the majority of the nervous system.The peripheral nervous system (PNS) is the part of the nervous system that consists of the nerves and ganglia outside of the brain and
