Placenta An Important Stem Cell Source

Placenta An Important Stem Cell Source

Doctors are more often seeking to cure people who have leukemia and other blood-related disorders by giving them stem cell-rich bone marrow from donors who have closely matched tissue and blood types. The transplanted bone marrow makes healthy blood cells to replace the damaged or sickly ones. However, if the donor has a different tissue type, the recipient’s body will not recognize the new cells and will attack them, leading to what is known as graft-versus-host disease.

Placental stem cells, like umbilical cord blood, are much more tolerant with respect to matching. An advantage of placental stem cells is that they do not require an ideal match needed for those who have bone marrow transplants.

These stem cells appear to have distinct advantages in the fight against many diseases, and they may one day provide an alternative treatment for people who cannot find matching bone marrow donors, scientists said.

Researchers at the Children’s Hospital in Oakland, California obtained placentas from consenting mothers who had cesarean sections. The study of these placenta-obtained stem cells shows that research in California doesn’t focus solely on embryonic stem cells, which have the ability to transform into any cell type.
