Singapore biotech firm discovers new source of stem cells

A Singapore biotech company, CellResearch Corporation, has discovered a new source of stem cells - from the umbilical cord lining. While cord blood stem cells are rich largely in hematopoietic cells which form blood cells, they lack sufficient mesenchymal and epithelial stem cells, both of which are are responsible for creating virtually every cell in the body. Stem cells can also be found in marrow, muscle, skin, nervous tissue and fat. However, their extraction would require surgical intervention which is both uncomfortable and has potential risks. CellResearch Corporation's breakthrough is identifying an alternative source of stem cells that is not only easily accessible, but also possesses both epithelial and mesenchymal stem cells.
