Abstract (original English)
Mesenchymal stem cells (MSCs) can differentiate toward epithelial cells and may be used as an alternative source for generation of heterotypical artificial human skin substitutes, thus, enhancing their development and translation potential to the clinic. The present study aimed at comparing four types of heterotypical human bioengineered skin generated using MSCs as an alternative epithelial cell source. Adipose-tissue-derived stem cells (ADSCs), dental pulp stem cells (DPSCs), Wharton's jelly stem cells (WJSCs) and bone marrow stem cells (BMSCs) were used for epidermal regeneration on top of dermal skin substitutes. Heterotypic human skin substitutes were evaluated before and after implantation in immune-deficient athymic mice for 30 d. Histological and genetic studies were performed to evaluate extracellular matrix synthesis, epidermal differentiation and human leukocyte antigen (HLA) molecule expression. The four cell types differentiated into keratinocytes, as shown by the expression of cytokeratin 10 and filaggrin 30 d post-grafting; also, they induced dermal fibroblasts responsible for the synthesis of extracellular fibrillar and non-fibrillar components, in a similar way among each other. WJSCs and BMSCs showed higher expression of cytokeratin 10 and filaggrin, suggesting these cells were more prone to epidermal regeneration. The absence of HLA molecules, even when the e
