Abstract
Background: Mesenchymal stem cells (MSCs) can be used to treat premature ovarian failure (POF). Different methods have already been applied to detect MSCs in tissues. This study aimed to investigate the quantitative distribution of CM-DiI-labeled human umbilical cord vein MSCs (hUCV-MSCs) in different regions of the ovarian tissue of the cyclophosphamide ( CTX )-induced POF in mice. Methods: Adult female C57BL/6 mice (n = 40) were divided into four groups: (1) Mice receiving PBS as control (Ctrl) group; (2) mice receiving hUCV-MSCs intravenously as Ctrl + hUCV-MSCs group; (3) mice receiving CTX intraperitoneally (i.p.) as CTX group; (4) mice receiving CM-DiI-labeled hUCV-MSCs after CTX injection as CTX + hUCV-MSCs group. Histological changes and CM-DiI-labeled hUCV-MSCs distribution were analyzed in the ovarian tissues. Quantitative real-time PCR was performed to detect human mitochondrial cytochrome b (MTCYB) gene in the ovarian tissues of the mice. Results: The mean number of the fluorescent hUCV-MSCs was 20 ± 2.5 (57.1%) in the medulla, 11.3 ± 2.8 (32.2%) in the cortex, and 5.5 ± 1 (15%) in the germinal epithelium of the ovarian tissue (p < 0.05). Moreover, MTCYB gene was detected in the mice ovaries of the CTX + hUCV-MSCs group, but not in other groups. Conclusion: Our findings suggest that the distribution of the transplanted hUCV-MSCs in different regions of the ovarian tissue is not equal, and it is greater in the medulla than the cortex and germinal epithelium. This is the first report of quantitative distribution of MSCs in different regions of ovarian tissue in the POF model.
