Abstract

Stem cell transplantation is a promising strategy for delayed wound healing caused by chemotherapy. However, the fate of stem cells under chemotherapy has not been fully elucidated. Herein we characterized human fetal bone marrow stromal cells (hBMSCs) during wound healing in mice treated with cyclophosphamide (CTX). The isolated hBMSCs expressed the phenotype of CD11b^low/CD14^low/CD34^low/CD45^low/CD29^high/CD44^high/CD90^high/CD105^high/CD146^high/STRO-1^low. Following in vitro exposure to CTX, hBMSCs showed decreased cell growth in a dose- and time-dependent manner, accompanied by increased expressions of collagen-I/III, and CD31. After transplantation, wounds closed as early as 8 days and were positive for α-smooth muscle actin (α-SMA), implicating the enhanced re-epithelialization and wound contraction. Moreover, proliferating cell nuclear antigen (PCNA) and CD31 showed co-localization with α-SMA, suggesting the differentiation of hBMSCs into epithelial cells and myofibroblasts/fibroblasts. Taken together, our results indicate hBMSCs can accelerate wound healing under chemotherapy through altering their phenotypes.
