How can blood vessels and stem cells be used together for arthritis treatment?



Researchers at the Cornell University School of Medicine have discovered that endothelial cells, cells that line blood vessels, produce growth hormones that can grow enormous numbers of stem cells over a period of a few short weeks. Dr. Antonio Gotto, lead investigator, said that this indicates that blood vessels are not just bystanders but are active participants in the maturation of stem cells into adult organs. This vascular cell model could also be used to grow stem cells from different organs. By being able to direct stem cells to either multiply or differentiate, the researchers maintain control. They feel their endothelial cell model could serve as a reservoir for stem cell production. Of importance is that despite the length of time and multiple proliferation cycles, there was no evidence of malignant transformation.
