Umbilical cord blood stem cells
Umbilical cord blood stem cells are harvested from umbilical cord blood after a baby is born. Harvest does not affect the care of the baby or the mother.
Umbilical cord stem cells are less likely to result in graft-versus-host disease after a transplant. In this disease, the newly transplanted cells may destroy the other cells in the host's body because the cells do not match the others well enough.
Harvesting umbilical cord blood stem cells
Umbilical cord blood is drawn from the umbilical cord and placenta after the cord has been clamped and cut. Although stem cells are concentrated in cord blood, few cells are collected because the total amount of blood is small. The stem cells are usually frozen for later use.
