Abstract
Intrauterine adhesion (IUA) caused by endometrial injury is the most common cause of female uterine infertility. Current treatments offer limited clinical benefits. In this study, we investigated the role of human umbilical cord mesenchymal stem cells (hUCMSCs) loaded collagen scaffold in the regeneration of injured human endometrium in an IUA rat model. Following the construction of the IUA rat model by mechanical injury, collagen scaffold, hUCMSCs, or hUCMSCs-loaded collagen scaffold was transplanted. The implantation of hUCMSCs-loaded collagen scaffold significantly increased the thickness of the endometrium, the number of endometrial glands and the abundance of blood vessels in IUA rats. Moreover, hUCMSCs-loaded collagen scaffold treatment significantly reduced endometrial fibrosis, increased the expression of Vegf, Integrin β3, Lif, and Igf-1, and finally improved endometrial receptivity in IUA rats. Taken together, our observations suggest that hUCMSCs-loaded collagen scaffold could be a practical therapeutic for treating IUA and restoring regeneration.
期刊介绍：
International Journal of Stem Cells (Int J Stem Cells), a peer-reviewed open access journal, principally aims to provide a forum for investigators in the field of stem cell biology to present their research findings and share their visions and opinions. Int J Stem Cells covers all aspects of stem cell biology including basic, clinical and translational research on genetics, biochemistry, and physiology of various types of stem cells including embryonic, adult and induced stem cells. Reports on epigenetics, genomics, proteomics, metabolomics of stem cells are welcome as well. Int J Stem Cells also publishes review articles, technical reports and treatise on ethical issues.
