Researchers in the U.S. say they may have found a new and better source for harvesting stem cells: the placentas that are often discarded after birth.
The research from Children’s Hospital & Research Center Oakland found there are far more stem cells in placentas than in umbilical cord blood, the traditional source for stem cells, and they can be safely extracted for transplantation.
“Yes, the stem cells are there; yes, they are viable; and yes, we can get them out,” declared Dr. Frans Kuypers, one of the scientists who led the research with fellow scientist Vladimir Serikov.
The study was
An innovative experimental treatment for boosting the effectiveness of blood stem-cell transplants with umbilical cord blood has a favorable safety profile in long-term animal studies, according to Harvard Stem Cell Institute (HSCI) scientists at Dana-Farber Cancer Institute (DFCI), Beth Israel Deaconess Medical Center (BIDMC), and Children’s Hospital Boston (CHB).
Analysis of long-term safety testing in nonhuman primates, published online by the journal Cell Stem Cell in a new section called “Clinical Progress,” revealed that a year following transplant umbilical cord blood units treated with a signaling molecule called 16,16-dimethyl PGE2 reconstituted all the normal types
