More Multipotent Stem Cells Discovered

From EurekAlert!: "The scientists [identified] cells known as pericytes that are multipotent, meaning they have broad developmental potential. Pericytes are found on the walls of small blood vessels such as capillaries and microvessels throughout the body and have the potential to be extracted and grown into many types of tissues ... We believe pericytes represent one of the most promising sources of multipotent stem cells that scientists have been searching for in the quest to make regenerative medicine possible. ... These cells can be extracted easily and painlessly from convenient sources such as fat tissue, dental pulp, umbilical cord and placental tissue, then grown in culture to large numbers and, possibly, re-injected into the patient to heal a broken bone, a failing joint or an injured muscle. ... researchers were able to identify pericytes in all human tissues they analyzed, including muscle, fat, pancreas, placenta and many other samples. Through purification in the lab, these pericytes could then be coaxed into becoming whatever type of tissue the scientists desired. For instance, the researchers took pericytes from the pancreas and then reinjected them into an injured muscle. The cells immediately began regenerating muscle tissue."
