stem cells

All plants and animals have stem cells or unspecialized cells that have the ability to become any one of specialized types of cells. Adults also have these types of cells, one of which is HSC. HSC's form new blood cells to replace old and damaged white and red blood cells. Scientists at Rice University believe these HSC cells are master regulator cells. This is interesting to them because it can lead information about other master regulator cells like embryonic stem cells. The complete article can be found here.
