The use of stem cells for treatment has become a growing interest in the scientific community. Distinguishing between an ESC and its intermediate progenitor is nearly impossible, so research is now being done broadly on EPCs. One study showed that brief exposure to sevoflurane promoted growth and proliferation of EPCs. Sevoflurane is used in general anesthesia, but this finding shows the potential to induce endothelial progenitors. Using stem cells for cell replacement therapies is known as "regenerative medicine", which is a booming field that is now working on transplanting cells as opposed to bigger tissues or organs. There was another study done that also showed that after exposure to sevoflurane, the EPCs were able to adhere to endothelial cells better. When combining the results from both of the studies, results show that sevoflurane was able to improve the function of EPCs significantly in three different areas of interest.
