Abstract (original English)

Chronic non-healing wounds are detrimental for the quality of life of the affected individuals and represent a major burden for the health care systems. Adipose-derived stem cells (ASCs) are being investigated for the development of novel treatments of chronic wounds, as they have shown several positive effects on wound healing. While these effects appear to be mediated by the release of soluble factors, it is has also become apparent that the extracellular matrix (ECM) deposited by ASCs is essential in several phases of the wound healing process. In this work, we describe an approach to produce ECM scaffolds derived from ASCs in culture. Upon growth of ASCs into an overconfluent cell layer, a detergent-based cell extraction approach is applied to remove the cellular components. The extraction is followed by an enzymatic treatment to remove the residual DNA. The resultant cell-derived scaffolds are depleted of cellular components, display low DNA remnant, and retain the native fibrillar organization of the ECM. Analysis of the molecular composition of the ECM scaffolds revealed that they are composed of collagens type I and III, and fibronectin. The decellularized scaffolds represent a substrate that supports adhesion and proliferation of primary human fibroblasts and dermal microvascular endothelial cells, indicating their potential as platforms for wound healing studies.
