Riding the spermatogenic wave: Profiling gene expression within neonatal germ and Sertoli cells during a synchronized initial wave of spermatogenesis

ABSTRACT: WIN 18,446/RA treatment of neonatal mice was used to synchronize the initial wave of spermatogenesis and identify novel messages expressed within either germ or Sertoli cells as spermatogonia enter meiosis.

Effects of deletion of Arhgef15 gene in mouse sertoli cells on spermatogenesis

Project description:Sertoli cells, which are the only somatic cells in the seminiferous tubules, facilitate the maintenance of testicular immune privilege through the formation of the blood-testis barrier (BTB) and the expression of immunoregulatory factors. Rho guanosine exchange factor 15 (ARHGEF15) is a member of guanosine exchange factors, which are involved in cell migration, cell polarity, and cell cycle progression via activation of Rho GTPases. This study investigated the functions of ARHGEF15 in Sertoli cells during spermatogenesis using Sertoli cell–specific Arhgef15 knockout mice. The results showed that Arhgef15 deficiency in Sertoli cells affected the localization of Sertoli cell nuclei, disrupted BTB integrity, and led to premature shedding of germ cells. In Arhgef15flox/flox/Amh-Cre+ mice, the ultrastructure of the round spermatids was impaired, accompanied by acrosome degeneration, acrosomal vesicle shedding, and atrophic nuclei. Consequently, the percentage of abnormal sperm in the Arhgef15flox/flox/Amh-Cre+ epididymis was markedly elevated. RNA-sequencing analysis revealed that most of the differentially expressed genes in Sertoli cells of Arhgef15flox/flox/Amh-Cre+ mice were related to immunity. Further study revealed that the sera of Arhgef15flox/flox/Amh-Cre+ mice showed immunoreactivity against testicular lysate of wild-type mice, indicating the production of antibodies against testicular autoantigens in Arhgef15flox/flox/Amh-Cre+ mice. In conclusion, the specific deletion of Arhgef15 in Sertoli cells leads to sperm abnormality, probably by disrupting the testicular immune homeostasis, in mice.

Specific deletion of protein phosphatase 6 catalytic subunit in Sertoli cells leads to disruption of spermatogenesis

Project description:Protein phosphatase 6 (PP6) is a member of the PP2A-like subfamily, which plays significant roles in numerous fundamental biological activities. We found that PPP6C plays important roles in male germ cells recently. Spermatogenesis is supported by the Sertoli cells in seminiferous epithelium. In this study, we crossed Ppp6cF/F mice with AMH-Cre mice to gain mutant mice with specific depletion of the Ppp6c gene in the Sertoli cells. We discovered that the PPP6C cKO male mice were absolutely infertile and germ cells were largely lost during spermatogenesis. By combing phosphoproteome with bioinformatics analysis, we showed that the phosphorylation status of β-catenin at S552 (a marker of adherens junctions) was significantly upregulated in mutant mice. Abnormal β-catenin accumulation resulted in impaired testicular junction integrity, thus led to abnormal structure and functions of BTB. Taken together, our study reveals a novel function for PPP6C in male germ cell survival and differentiation by regulating the cell-cell communication through dephosphorylating β-catenin at S552.

Sertoli cells are the unique source of stem cell factor for spermatogenesis

Project description:To systematically investigate the expression patterns of all potential niche factors in testis, we performed single-cell RNA sequencing (scRNA-seq) of all testicular somatic cell types. To enrich somatic cells, we depleted Tomato+ cells from the testes of 2-month-old Ddx4-creER; R26tdTomato mice at 4 weeks after tamoxifen treatment. Then the cells were further captured with 10x Genomics platform. After analysis of the integrated data, we mapped the expression patterns of all known niche factors in testicular somatic cells. We also performed scRNA-seq of testicular cells from 6-week-old control and Amh-cre;Scf fl/fl mice to study the effect of Scf conditional knockout from Sertoli cells on spermatogenesis. By scRNA-seq data analysis, we found that conditional knockout of Scf from Sertoli cells blocks spermatogenesis by depleting differentiating spermatogonia

Mouse sertoli cells Palmitoylated protein MS

Project description:Elevated palmitic acid, a most abundant saturated fatty acid, is a risk factor for obesity complications. Here, we report that palmitic acid impairs spermatogenesis by inducing abnormal palmitoylation in Sertoli cells. Firstly, we proposed a correlation between palmitic acid and spermatogenesis by reporting a significant elevation of serum palmitic acid levels in patients with dyszoospermia. In palmitic acid -treated mice, the blood-testis barrier was found to be disrupted, and decreased tight junction protein expression was observed in palmitic acid-treated Sertoli cells. Palmitic acid entered the endoplasmic reticulum and induced endoplasmic reticulum stress, resulting in damage to Sertoli cell barriers.
