Great link Longhorn....I especially take an interest in the text in Red.
Stem Cells Repair Wounds
Stem cells are like minor miracles: They help generate new kinds of cells and can aid in disease research. In a new study at the Hospital for Sick Children in Toronto, scientists have discovered that skin-derived precursors (SKPs) on skin (shown here) help stem cells to cause a wound to heal.
This is an important finding because SKPs maintain skin and promote healing, and also cause hair follicles to grow. Once scientists understand how SKPs cause this repair, new drugs could be developed that trigger stem cells into action and help treat diseases such as those in the spinal cord.
