95% of the body’s testosterone is produced by the Leydig Cells (LCs) in adult testis, and LC functional degradation can cause testosterone deficiency ultimately leading towards hypogonadism. The transplantation of LCs derived from stem cells is a very promising therapy to overcome the testosterone deficiency. The isolated umbilical cord mesenchymal stem cells (UMSCs) were identified by flow cytometry and adipogenic and osteogenic differentiation. Western blotting and reverse transcription polymerase chain reaction (RT-PCR) were used for the differentiated Leydig-like cell identification. The comparisons of the testosterone levels, gene expression levels, and cyclic adenosine monophosphate (cAMP) productions were performed through radioimmunoassay, quantitative polymerase chain reaction (qPCR), and cAMP assay kit, respectively. Here, it is stated that our isolated human UMSCs, which could positively express CD29, CD44, CD59, CD90, CD105, and CD166 but negatively express CD34 as well as could be differentiated into adipocytes and osteocytes, could be differentiated into Leydig-like cells (UMSC-LCs) using a novel differentiation method based on molecular compounds. The enrichment UMSC-LCs could secrete testosterone into the medium supernatant and produce considerable cAMP at the stimulation of luteinizing hormone (LH), and positively expressed LC lineage-typical markers LHCGR, SCARB1, SATR, CYP11A1, CYP17A1, HSD3B1, HSD17B3, and SF-1 as well as negatively expressed mesenchymal stem cell typical markers CD29, CD44, and CD105. The expression levels of NR3C4, PDGFRA, and NR3A1 in UMSC-LCs were higher than those of UMSCs and were comparable with LCs. These results illuminated that UMSCs could be differentiated into Leydig-like cells using the defined molecular compounds, which might further support MSC-derived Leydig cell transplantation therapy for testosterone insufficiency.

将人脐带间充质干细胞分化为具有特定分子化合物的 Leydig 样细胞。

人体 95% 的睾酮是由成人睾丸中的睾丸间质细胞 (LC) 产生的,而 LC 功能退化会导致睾酮缺乏,最终导致性腺功能减退。来自干细胞的 LC 移植是克服睾酮缺乏症的一种非常有前景的疗法。分离的脐带间充质干细胞 (UMSCs) 通过流式细胞术和成脂和成骨分化进行鉴定。Western印迹和逆转录聚合酶链反应(RT-PCR)用于分化的Leydig样细胞鉴定。睾酮水平、基因表达水平和环磷酸腺苷 (cAMP) 产量的比较分别通过放射免疫测定法、定量聚合酶链反应 (qPCR) 和 cAMP 测定试剂盒进行。这里,据称,我们分离的人 UMSCs 可以正表达 CD29、CD44、CD59、CD90、CD105 和 CD166,但负表达 CD34,并且可以分化为脂肪细胞和骨细胞,可以分化为 Leydig 样细胞(UMSC -LCs) 使用基于分子化合物的新型微分方法。富集的 UMSC-LCs 可在促黄体生成素 (LH) 的刺激下将睾酮分泌到培养基上清液中并产生大量 cAMP,并阳性表达 LC 谱系典型标志物 LHCGR、SCARB1、SATR、CYP11A1、CYP17A1、HSD3B1、HSD17B3 和 SF -1 以及负表达的间充质干细胞典型标志物 CD29、CD44 和 CD105。的表达水平 和 CD166 但负表达 CD34 并且可以分化为脂肪细胞和骨细胞,可以使用基于分子化合物的新型分化方法分化为 Leydig 样细胞 (UMSC-LCs)。富集的 UMSC-LCs 可在促黄体生成素 (LH) 的刺激下将睾酮分泌到培养基上清液中并产生大量 cAMP,并阳性表达 LC 谱系典型标志物 LHCGR、SCARB1、SATR、CYP11A1、CYP17A1、HSD3B1、HSD17B3 和 SF -1 以及负表达的间充质干细胞典型标志物 CD29、CD44 和 CD105。的表达水平 和 CD166 但负表达 CD34 并且可以分化为脂肪细胞和骨细胞,可以使用基于分子化合物的新型分化方法分化为 Leydig 样细胞 (UMSC-LCs)。富集的 UMSC-LCs 可在促黄体生成素 (LH) 的刺激下将睾酮分泌到培养基上清液中并产生大量 cAMP,并阳性表达 LC 谱系典型标志物 LHCGR、SCARB1、SATR、CYP11A1、CYP17A1、HSD3B1、HSD17B3 和 SF -1 以及负表达的间充质干细胞典型标志物 CD29、CD44 和 CD105。的表达水平 富集的 UMSC-LCs 可在促黄体生成素 (LH) 的刺激下将睾酮分泌到培养基上清液中并产生大量 cAMP,并阳性表达 LC 谱系典型标志物 LHCGR、SCARB1、SATR、CYP11A1、CYP17A1、HSD3B1、HSD17B3 和 SF -1 以及负表达的间充质干细胞典型标志物 CD29、CD44 和 CD105。的表达水平 富集的 UMSC-LCs 可在促黄体生成素 (LH) 的刺激下将睾酮分泌到培养基上清液中并产生大量 cAMP,并阳性表达 LC 谱系典型标志物 LHCGR、SCARB1、SATR、CYP11A1、CYP17A1、HSD3B1、HSD17B3 和 SF -1 以及负表达的间充质干细胞典型标志物 CD29、CD44 和 CD105。的表达水平UMSC -LCs中的NR3C4、PDGFRA和NR3A1高于UMSCs LCs相当这些结果表明,使用确定的分子化合物可以将 UMSCs 分化为 Leydig 样细胞,这可能进一步支持 MSC 衍生的 Leydig 细胞移植治疗睾酮不足。
