Quali-quantitative differences of adipose tissuederived stromal cells from superficial and deep subcutaneous lipoaspirates: a matter of fat (original) (raw)

2014

Abstract

Subcutaneous fat (or hypoderm) represents a valuable reservoir of adiposederived stem cells (ASCs), residing in the stromal vascular fraction (SVF), widely exploited in regenerative medicine applications, being easily harvested through lipoaspiration. The lack for standardized procedures for autologous fat grafting, guided research efforts aimed at identifying possible differences related to the harvesting site, that may affect cell isolation yield, cell growth properties and clinical outcomes. The hypoderm features a complex architecture: the superficial fascia separates the superficial adipose tissue (SAT) from the deep layer (DAT). Aim of this study was to unravel the differences between SAT and DAT, considering morphological structure, SVF composition and ASCs’ properties. SAT and DAT specimens were collected from three distinct anatomical regions (abdomen, thigh and knee) of female individuals and comparatively analyzed through histology, flow citometry, and qPCR. ASCs were iso...
