Initially, tissue homeostasis is achieved by the formation of a platelet plug, followed by the arrangement of a fibrin matrix, which corresponds to the first structure through which inflammatory cells, such as neutrophils and macrophages, will infiltrate,. The first stage of repair, inflammation, begins soon after tissue damage and involves the blood coagulation cascade, inflammatory pathways and the immune system.

After an injury, a complex cascade of events is triggered, promoting repair through healing – a process described by inflammation, proliferation and remodeling phases – that restores tissue homeostasis but often not full functionality.

The skin is highly susceptible to trauma due to constant exposure to external factors. DSCs associated with Integra induced superior overall results than the Integra alone, whereas scaffolds with ASCs showed an intermediate effect, often not significantly better than the empty biomaterial.

In conclusion, both DSCs and ASCs were able to accelerate the healing of mice skin wounds and promote repair with scars of better quality and more similar to healthy skin than the empty scaffold. Besides, DSCs and ASCs reduced inflammation by induction of macrophage polarization from a pro-inflammatory (M1) to a pro-repair (M2) phenotype. However, the DSCs showed smaller scar size,superior extracellular matrix deposition, and greater number of cutaneous appendages. Both types of MSCs stimulated angiogenesis and extracellular matrix remodeling, leading to better quality scars. We found that the association of both DSCs and ASCs with the Integra accelerated wound closure in mice compared with the biomaterial only (control).

Human DSCs and ASCs were delivered to full-thickness mouse wounds by a collagen-based scaffold (Integra Matrix). Therefore, the aim of this study was to comparatively investigate, by a mouse model in vivo assay, the potential use of dermal-derived MSCs (DSCs) and adipose tissue–derived MSCs (ASCs) in improving skin wound healing. Although sharing essential characteristics, mesenchymal stromal cells (MSCs) isolated from different tissues might have distinct properties. In this context, tissue engineering and cellular therapies are promising approaches. The process of wound healing restores skin homeostasis but not full functionality thus, novel therapeutic strategies are needed to accelerate wound closure and improve the quality of healing.
