Qilin Pills promote testicular spermatogenesis in azoospermia mice
OBJECTIVE: To investigate the effect of Qilin Pills (QP) in facilitating the recovery of spermatogenic function in azoospermia (AS) mice and to explore its mechanism of regulating testicular spermatogenesis.
METHODS: Fifteen 4-week-old male mice were equally randomized into an AS model control, a low-dose QP and a high-dose QP group. The AS model was established in the mice by intraperitoneal injection of busulfan at 35 mg/kg. After modeling, the animals in the low- and high-dose QP groups were treated with Qilin Pills intragastrically at 2 000 and 8 000 mg/kg/d respectively while those in the model control group fed on a normal diet, all for 28 days. Then, all the mice were sacrificed for examination of the ultrastructures of the epididymis and testis by HE staining, detection of the specific markers of spermatogenic, Sertoli and Leydig cells by Western blot, and determination of the expressions of these markers in the testis tissue by immunofluorescence assay.
RESULTS: The number of spermatogenic cells in the testis tissue was significantly decreased in the AS model controls, with no spermatozoa in most of the seminiferous tubules in the epididymis (Johnsen's score: 5.2 ± 0.5). In the high-dose QP group, spermatogenic cells were tightly arranged with distinct layers in the seminiferous tubules, with a large number of spermatozoa but no non-sperm cells in the lumens of the epididymis (Johnsen's score: 9.4 ± 0.6). The number of spermatogenic cells in the testis was increased in the low-dose QP group with some spermatozoa in the seminiferous tubules as compared with that in the model control, but lower than in the high-dose group (Johnsen's score: 7.6 ± 0.6). The Johnsen's score was significantly lower in the model control than in the high- and low-dose QP groups (P < 0.01), and higher in the high-dose than in the low-dose QP group (P < 0.05). The expressions of the specific markers of Sertoli cells SCF, BMP4, SYCP3, DMC1 and Ki67 were also remarkably lower in the model control than in the high- and low-dose QP groups (P < 0.01), and higher in the high-dose than in the low-dose QP group (P < 0.05 or P < 0.01). No statistically significant differences were observed among the three groups of mice in the markers of spermatogonial stem cells (SSC) and undifferentiated SSCs UCHL1, STRA8, NGN3 and PLZF3 (P > 0.05). The expressions of the spermatocyte markers DMC1 and SYCP3 were markedly lower in the model control than in the high- and low-dose QP groups (P < 0.05 or P < 0.01), and higher in the high-dose than in the low-dose QP group (P < 0.05 or P < 0.01). The Ki67 fluorescence signals were distributed in the spermatogonia, with a higher intensity in the model control than in the high- and low-dose QP groups. The acrosome marker PNA was found mainly in the seminiferous tubules, with abundant fluorescence signals in the high- and low-dose QP groups but no obvious dot signals in the model controls.
CONCLUSIONS: Qilin Pills may contribute to the meiosis of spermatogonia and promote spermatogenesis by improving the function of Sertoli cells in the testis.
