Q: Question: Do adipose-derived mesenchymal stem cells from ventral hernia repair patients demonstrate decreased vasculogenesis?
Answer: ASCs derived from VHR patients appear to express fewer vasculogenic markers and form fewer tubules in Matrigel than ASCs from abdominoplasty patients, suggesting decreased vasculogenic activity.
A:
yes
