OLDSMAR, Fla., May 7 /PRNewswire-FirstCall/ -- Researchers at Cryo-Cell International Inc. (OTC Bulletin Board: CCEL - News), one of the world’s largest cord blood banks, have isolated a new type of adult stem cell with potential for treating a broad range of diseases in the future. The stem cell, called a maternal placental stem cell (MPSC), is taken from the discarded placental tissue immediately after childbirth. Like stem cells recovered from umbilical cord blood, these cells may be collected without any risk to the mother or child.
