文题释义:
睾丸间质细胞:
成群分布在曲精小管之间,胞体呈圆形、椭圆形或不规则形,胞体较大,直径约20 μm,胞质呈嗜酸性,细胞核呈圆形或卵圆形,常位于中央,染色较淡,有1个或2个核仁,线粒体多,呈管嵴状,无分泌颗粒。从青春期开始,睾丸间质细胞受垂体前叶嗜碱性细胞分泌的间质细胞刺激素(黄体生成素)的作用,能合成分泌雄性激素,可促进精子的发生和男性生殖器官发育,以及维持第二性征和性功能。
3β-羟基类固醇脱氢酶(3β-hydroxysteroid dehydrogenase,3β-HSD):是一类依赖于NAD+/NADP+接受质子的氧化还原酶。在胆固醇转化为类固醇激素中起限速酶作用,在体内广泛分布。3β-羟基类固醇脱氢酶催化孕烯醇酮生成孕酮,17α-羟孕烯醇酮转化为17α-羟孕酮,雄烯二醇生成睾酮等多步化学反应。3β-羟基类固醇脱氢酶通过参与细胞内类固醇激素生成,进而在生殖系统中发挥功能。

 

摘要
背景:
近年来干细胞的发展,为治疗雄激素缺乏疾病提供了新的思路。
目的:探讨脂肪间充质干细胞是否可分化为睾丸间质细胞。
方法:取生长状态良好的第3代大鼠脂肪间充质干细胞,分2组培养:实验组加入0.1 mg/L人绒毛膜促性腺激素、10.0 μg/L血小板源性生长因子及10.0 μg/L碱性成纤维细胞生长因子,进行向睾丸间质细胞的诱导培养;对照组不加入上述细胞生长因子,常规培养。诱导培养1,7,14,21 d,进行相关指标检测。
结果与结论:①免疫荧光染色:对照组无3β-羟基类固醇脱氢酶(3β-hydroxysteroid dehydrogenase,3β-HSD)阳性细胞;实验组可见3β-HSD阳性细胞,并且随着诱导时间的延长,3β-HSD阳性细胞逐渐增多,荧光染色增强;②睾酮分泌水平:对照组无睾酮分泌;诱导培养7 d后,实验组检测到睾酮分泌,并且随着诱导时间的延长,睾酮分泌增加;③RT-PCR检测:对照组无黄体生成素受体、类固醇合成急性调节蛋白、3β-HSD阳性条带;实验组诱导培养7 d后,可见黄体生成素受体、类固醇合成急性调节蛋白、3β-HSD阳性条带,并且随着诱导培养时间的延长,阳性条带增强;④结果表明,脂肪间充质干细胞可分化为睾丸间质细胞。

Abstract:

BACKGROUND: The recent development of stem cells has provided new ideas for the treatment of androgen-deficient diseases.
OBJECTIVE: To investigate whether adipose-derived mesenchymal stem cells can differentiate into Leydig cells.
METHODS: Passage 3 rat adipose-derived mesenchymal stem cells that grew well were taken and cultured in the medium with (experimental) or without (control) 0.1 mg/L human chorionic gonadotropin, 10.0 μg/L platelet-derived growth factor and 10.0 μg/L basic fibroblast growth factor. Indicator detection was done at 1, 7, 14, 24 days of induced culture.
RESULTS AND CONCLUSION: (1) Immunofluorescence staining results showed that there were no 3β-hydroxysteroid dehydrogenase (3β-HSD) positive cells in the control group, while the number of 3β-HSD positive cells was gradually increased in the experimental group with the induction time, which presented with fluorescence enhancement. (2) There was no secretion of testosterone in the control group, while in the experimental group, testosterone secretion was detected at 7 days of induced culture, and moreover, the testosterone level was increased with the induction time. (3) RT-PCR findings showed no luteinizing hormone receptor, steroidogenic acute regulatory protein, and 3β-HSD positive bands in the control group, while these positive bands appeared in the experimental group after 1 day of induction, and strengthened with the induction time. To conclude, adipose-derived mesenchymal stem cells can be induced to differentiate into Leydig cells.
