Medical researchers hope they can be used to grow specific tissues or organs.There are three types of stem cells: totipotent, pluripotent, and multipotent.A single totipotent stem cell can grow into an entire organism.nother controversy in the use of embryonic stem cells is the use of therapeutic cloning. This involves the cloning of early embryos from which stem cells are harvested, providing a larger source of the cells. Many see this as encouraging human cloning, which they think could be dangerous or unethical.
Precursor cells are stem cells that have developed to the stage where they are committed to forming a particular kind of new blood cell. Read More In blood: Blood cells Precursor cells are stem cells that have developed to the stage where they are committed to forming a particular type of new blood cell. By dividing and differentiating, precursor cells give rise to the four major blood cell lineages: red cells, phagocytic cells, megakaryocytes, andâ¦ Read More reticuloendothelial system
