Blood vessel forming potential of stem cells from human placenta and umbilical cord blood
This study compared endothelial colony-forming cells derived from human placenta to those derived from human umbilical cord blood to find which were more proliferative and better at forming new blood vessels. Circulating ECFCs from umbilical cord blood and those from human placenta are phenotypically identical with equivalent proliferative potential. However, researchers found that ECFCs from placenta formed significantly more blood vessels than those derived from umbilical cord blood. The placenta-derived cells were also more vasculogenic.
