what do you call the young bone-forming cells?
osteoblasts
osteoblasts are mononucleate bone-forming cells. they are located on the surface of osteon seams and make a protein mixture known as osteoid, which mineralizes to become bone. the osteoid seam is a narrow region of newly formed organic matrix, not yet mineralized, located on the surface of a bone. osteoid is primarily composed of type i collagen. osteoblasts also manufacture hormones, such as prostaglandins, to act on the bone itself. the osteoblast creates and repairs new bone by actually building around itself. first, the osteoblast puts up collagen fibers. these collagen fibers are used as a framework for the osteoblasts' work. the osteoblast then deposits calcium phosphate which is hardened by hydroxide and bicarbonate ions. the brand new bone created by the osteoblast is called osteoid. once the osteoblast is finished working it is actually trapped inside the bone once it hardens. when the osteoblast becomes trapped, it becomes known as an osteocyte. other osteoblasts remain on the top of the new bone and are used to protect the underlying bone, these become known as lining cells.

stem cell transplant is a process in which the blood-forming cells that are abnormal (like leukemia cells) or that were destroyed by chemotherapy are replaced with healthy new blood-forming cells. a stem-cell transplant can help the human body produce more healthy white blood cells, red blood cells, or platelets. it also reduces the risk of life-threatening conditions such as anemia, or hemorrhage. stem cell transplants can be done by obtaining cells from the bone-marrow, blood or umbilical-cord blood. stem cell transplants can use the cells from one's self, called an autologous stem cell transplant or they can use cells from another person, known as an allogenic stem cell transplant. the type used in childhood leukemia is typically allogenic. the donors used must be a match to the child getting the transplant by a marker called hla
