Multipotent Adult Progenitor Cells Grown Under Xenobiotic-Free Conditions Support Vascularization During Wound Healing

The study demonstrated that xenobiotic-free human multipotent adult progenitor cells (XF-hMAPC) effectively supported vascularization and improved wound healing in mice. The XF-hMAPC cells promoted the formation of mature blood vessels and enhanced wound closure, re-epithelialization, granulation tissue formation, and dermal collagen organization in a dose-dependent manner. The study involved 59 mice for early wound healing and 47 mice for late-stage wound healing, showing the potential of XF-hMAPC cells as an off-the-shelf allogeneic product for improving wound healing. The beneficial effects were attributed to the cells' paracrine actions rather than direct differentiation into endothelial cells, suggesting their viability as a clinical-grade cell therapy for enhancing wound healing and vascularization.
