The Purification Of Human Adult Progenitor Cell Types To Promote Angiogenesis, Stephen E. Sherman

Electronic Thesis and Dissertation Repository

Cellular transplantation strategies have aimed to combat critical limb ischemia (CLI) by inducing endogenous blood vessel regeneration. Transplantation of mesenchymal stromal cells (MSC) for CLI has proven safe and well-tolerated but demonstrated only modestly improved clinical outcomes explained in part by a lack of MSC survival and/or potency in ischemic tissues. This thesis focuses on the development of improved transplantation strategies for patients with CLI utilizing purified pro-angiogenic subsets of MSC and endothelial colony forming cells (ECFC) seeded within decellularized adipose tissue (DAT) bioscaffolds. First, I investigated whether purification of bone marrow-derived MSC based on a conserved stem cell function, …
