Combination therapy of placenta-derived mesenchymal stem cells and artificial dermal scaffold promotes full-thickness skin defects vascularization in rat animal model
Purpose
Recently, placenta-derived mesenchymal stem cells (PMSCs) have garnered considerable attention in tissue repair and regeneration. The present study was conducted to evaluate the effect of PMSCs on artificial dermal scaffold (ADS) angiogenesis and their combination therapy on wound closure.
Material and methods
Herein, the growth and survival of PMSCs in ADS were explored. CCK8, scratch wound, and tubule formation assays were employed to investigate the effects of ADS conditioned medium (CM) and ADS-PMSCs CM on human umbilical vein endothelial cells (HUVECs). The effect of ADS-PMSCs on full-thickness skin defects healing was evaluated based on a rat model. Wound healing progresses was meticulously investigated through hematoxylin and eosin (HE), Masson's trichrome, and immunohistochemical staining analyses.
Results
In vitro cell culture results demonstrated the proliferation of PMSCs in ADS. The ADS-PMSCs CM notably stimulated the proliferation, migration, and tube formation of HUVECs compared to the ADS CM group. In the rat full-thickness skin defect model, the ADS-PMSCs treatment significantly accelerated the vascularization area of ADS after 2 weeks. Besides, HE and Masson's trichrome staining results indicated that ADS-PMSCs treatment significantly enhanced fibroblast proliferation and collagen fiber 2 weeks after surgical procedure. Compared to the ADS group, collagen fiber arrangement was thicker in the ADS-PMSCs group. Immunohistochemical staining reinforced this finding, illustrating a substantial increase in CD31 expression within the ADS-PMSCs group.
Conclusions
The results suggest that the combination of ADS with PMSCs accelerates ADS vascularization by fostering granulation tissue development and boosting the formation of new blood vessels.
