A sophisticated system to derive blood cell precursors from individual pluripotent stem cells (hPSC) has now been developed by experts. This type of stem cell has the potential to develop into many different types of cells in the body, and is capable of participating in organ restoration and function. These qualities have prompted scientists to check the use of hPSC to treat some diseases. However , the development of a completely defined system to generate functional blood cell precursors offers proven to be a significant challenge.
