The Basics of Placental and Cord Blood Stem Cells

The placenta is a temporary organ that accompanies pregnancy. It is implanted in the wall of the uterus, where it receives nutrients and oxygen from the mother's blood and eliminates waste from the fetus. The placenta also serves as a barrier that filters out some substances that could harm the fetus. The placenta is connected to the fetus via the umbilical cord which is, of course, the lifeline to the fetus. When the baby is delivered, the placenta is delivered afterward, which is why it is sometimes referred to as the afterbirth. This temporary organ contains placental stem cells which, like cord blood stem cells, can be collected only at the time of birth.

Placenta-derived stem cells are those stem cells that remain in the placenta after cord blood collection. The placenta is a particularly rich source of CD34+ hematopoietic (blood-forming) cells, similar to those found in cord blood. CD34+ cells can transform into many other cell types including red blood cells, white blood cells, and platelets. Stem cell transplants with a higher number of CD34+ cells have been associated with an improved rate of successful engraftment.
