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.
Most of the time, each cell has a specific job to do. One cell can't do what another cell can, just as a doctor isn't trained to design a bridge and an engineer can't do surgery. So cells work as a team, grouping together to make up our tissues and organs. But one type of cell is different. Stem cells can develop into cells with different skills. In that way, stem cells are like students who have the choice of studying to be either doctors or engineers. None of the body's other cells can become new cells like this. Blood Stem Cells. When you hear about stem cell transplants, they probably involve hematopoietic (pronounced: heh-mat-uh-poy-ET-ik) stem cells. These stem cells are produced in the bone marrow and form blood and immune system cells. Hematopoietic stem cells can become any of three different types of blood cells: red blood cells that carry oxygen; white blood cells that fight infection; platelets that help blood to clot
