Stem cells

Stem cells are parent cells from which all other blood cells (red blood cells, white blood cells and platelets) develop.

Bone marrow constitutes the factory that produces stem cells. It is a soft and gelatinous tissue that fills the inside of bones such as the sternum or the pelvis. Bone marrow differs from spinal marrow: spinal marrow is the part of the nervous system that descends inside the vertebral column.

Stem cells are found primarily in bone marrow. They are also found in small quantities in a person’s peripheral bloodstream.

Umbilical cord blood from newborn children is another source of stem cells.
