Umbilical Cord Blood Stem Cells

After a baby is born, the umbilical cord can be set aside and used as a source of stem cells. The umbilical cord blood is a rich source of stem cells that can be substituted for bone marrow stem cells.

Umbilical cord blood stem cells are rejected less often by the host tissue, possibly because they have not developed cell-surface molecules that can be recognized and attacked by the host’s immune system.
