文题释义:
精原细胞:原始的胚细胞经分化形成精原细胞,精原细胞经复制形成初级精母细胞,初级精母细胞经过第1次减数分裂后形成次级精母细胞,再经过第2次减数分裂形成精细胞。精细胞经过变形最终形成精子。精子的数量和质量直接影响着机体的生育能力。
细胞增殖标记物BrdU:BrdU为胸腺嘧啶的衍生物,可代替胸腺嘧啶在DNA合成期(S期),活体注射或细胞培养加入,而后利用免疫细胞化学,显示增殖细胞。同时结合其他细胞标记物,双重染色,可判断增殖细胞的种类,增殖速度,对研究细胞动力学有重要意义。因组织细胞内无内源性BrdU存在,所以BrdU应用较广。
 
背景:临床研究显示补肾填精中药能够促进精原干细胞的增殖和分化。
目的:验证养精胶囊提取液对精原干细胞增殖的影响。
方法:取雄性小鼠睾丸,分离精原干细胞,用无血清培养液同步化24 h后,加入10,50,100 mg/L养精胶囊提取液24 h,观察对精原干细胞活性、增殖及细胞周期变化。
结果与结论:①与对照组相比,养精胶囊提取液干预的细胞数量增加、活力增强、S期细胞比例增加,BrdU标记的精原干细胞的数量增加,其中以50 mg/L养精胶囊提取液的效果最为显著;②提示养精胶养精胶囊提取液能促进精原干细胞的增殖和促进精原干细胞活力的增加。

Abstract:

BACKGROUND: Chinese herbs for kidney nourishment can promote the proliferation and differentiation of spermatogonial stem cells.

OBJECTIVE: To verify the effect of seminiferous capsule extract on spermatogonial stem cell proliferation.
METHODS: Spermatogonial stem cells were isolated from the testis of male mice and synchronized by serum-free medium followed by an addition of 10, 50, 100 mg/L seminiferous capsule extracts. After 24 hours of culture, viability, proliferation and cell cycle of spermatogonial stem cells were observed.
RESULTS AND CONCLUSION: Compared with the control group, seminiferous capsule extracts promoted the cell number, viability and proportion at S stage. The number of BrdU-labeled spermatogonial stem cells was increased significantly after intervention with seminiferous capsule extracts, especially at the concentration of 50 mg/L. These findings indicate that seminiferous capsule extracts can promote the proliferation and viability of spermatogonial stem cells.
