22 23 stem cells travel through the bloodstream, and eventually, to the bone marrow, where they begin to produce new white blood cells, red blood cells, and platelets. It takes 10â14 days for the newly produced blood cells to enter the bloodstream in substantial numbers.
Stem cell. Stem cells are cells which are not terminally differentiated and are therefore able to produce cells of other types. 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.
