The Fate of Adipocytes after Nonvascularized Fat Grafting

Abstract

The authors show convincing evidence of very dynamic remodeling of adipose tissue after nonvascularized grafting. The authors observed three zones from the periphery to the center of the graft: the surviving area (adipocytes survived), the regenerating area (adipocytes died, adipose-derived stromal cells survived, and dead adipocytes were replaced with new ones), and the necrotic area (both adipocytes and adipose-derived stromal cells died).
