red marrow
Infants grow relatively fast and need quite a lot of red blood cells, which are only produced in red bone marrow. As the infants grow older, much of the red bone marrow is gradually replaced by yellow bone marrow containing a special kind of fat that gives it its yellowish color. If the body needs more red blood cells than the remaining red marrow is capable of producing, some of the yellow marrow changes to red marrow.
There is yellow bone marrow and red bone marrow.
Yes, that is correct. In newborn infants, the medullary cavity and all areas of spongy bone contain yellow bone marrow, which is mainly made up of fat cells. As the infant grows, red bone marrow gradually replaces the yellow bone marrow in these areas.
All bone marrow transplants require bone marrow from a donor; the purpose of the transplant is to replace the patient's bone marrow (that no longer works) with some that does work, which clearly cannot come from the patient (since they have none that works). Hence a donor must be used.
