Abstract

Androgen deficiency is a physical disorder that not only affects adults but can also jeopardize children's health. Because there are many disadvantages to using traditional androgen replacement therapy, we have herein attempted to explore the use of human umbilical cord mesenchymal stem cells for the treatment of androgen deficiency. We transplanted CM-Dil-labeled human umbilical cord mesenchymal stem cells into the testes of an ethane dimethanesulfonate (EDS)-induced male rat hypogonadism model. Twenty-one days after transplantation, we found that blood testosterone levels in the therapy group were higher than that of the control group (P = 0.037), and using immunohistochemistry and flow cytometry, we observed that some of the CM-Dil-labeled cells expressed Leydig cell markers for cytochrome P450, family 11, subfamily A, polypeptide 1, and 3-β-hydroxysteroid dehydrogenase. We then recovered these cells and observed that they were still able to proliferate in vitro. The present study shows that mesenchymal stem cells from human umbilical cord may constitute a promising therapeutic modality for the treatment of male hypogonadism patients.
