Discoveries in recent years have suggested that these cells have the ability to differentiate into a variety of cell types including bone cells, cartilage, and connective tissues, but they also have tremendous cellular activity and release potent growth factors. This phenomenon is referred to as stem cell transdifferentiation or plasticity. Under investigational protocols, these cells can be deployed to treat a number of degenerative conditions and diseases.
