The soft,spongy,inside portion of a bone is called bone marrow. It contains living cells and blood vessels. This is the place where blood cells of our body are made. Bones grow as we get older.
Bone marrow consists of stem cells, which are large, "primitive," undifferentiated cells supported by fibrous tissue called stroma. There are 2 main types of stem cells and, therefore, the bone marrow consists of 2 types of cellular tissue. One type of stem cell is involved in producing blood cells and the other is involved in producing stromal cells, which are responsible for the supporting stroma.
