...ide the brain and spinal cord are damaged,they can regenerate and may eventually reach their original target muscle torestore some function. Spinal cord and brain nerve axons, however, do notregenerate in mammals, and once separated from the cell body, they die. Theresult is paralysis.

... shown for the first time that the human liver can regenerate its tissue with a cell type from outside the organ -- and they present the first compelling evidence that those stem cells are human bone marrow. "Furthermore, we're talking about significant amounts of functional liver tissue -- up to 40 percent in ...The bone marrow is the source of mature liver cells

These cells, called stem cells, are recruited to the liver from the bone marrow and function as liver cells, according to a new study by New York University School of Medicine and Yale University School of Medicine scientists that proves for ...Cell transplants offer hope of brain repair following stroke
...ears ago, many people believed that the ability to regenerate neurons, or nerve cells, of the brain and spinal cord disappeared soon after birth. However, Rosenbaum's research team has shown that such repair processes can occur in mature brain cells at a very slow rate. In the current study researchers sought...Material could lead to self-healing cavities
