Single-cell atlas of rhesus monkey testis reveals aging- and season-dependent regulation of spermatogenesis and microenvironment homeostasis [RNA-Seq]

Listed in NCBI GEO

Spermatogenesis is a highly orchestrated process that depends on precise coordination between germ cells and the testicular microenvironment.

Description

However, how aging and seasonal shifts jointly regulate this process in nonhuman primates remains largely unexplored. Here, we generated a comprehensive single-cell transcriptomic atlas of the rhesus monkey testis across different ages and reproductive seasons.

Our analyses reveal that Sertoli cells actively regulate the blood–testis barrier (BTB) by dynamically remodeling tight and adherens junctions, thereby mediating seasonal fluctuations in meiotic germ cells. We further identified a previously uncharacterized SSC subpopulation (U3) enriched in the non-breeding season, defined by PDGF pathway activation. By integrating this pathway into a three-dimensional collagen–PDGF scaffold, we successfully established an in vitro rhesus SSC culture system with enhanced clonogenicity and long-term propagation.

In parallel, testicular immunosenescence emerged as a key determinant of age-related reproductive decline. We provide the first evidence that double-negative T cells (DNTs) markedly accumulate in aged testes, while pro-inflammatory macrophages (Mφ_SPAG16, M1-like) aberrantly expand during the non-breeding season, together disrupting immune homeostasis and niche support. Collectively, this study delineates the age- and season-dependent regulation of spermatogenesis in rhesus monkeys by integrating Sertoli–BTB dynamics, SSC niche signaling, and immune remodeling, thereby providing new mechanistic insights into testicular aging and reproductive homeostasis. experimental design:Following the manufacturer's protocol, cells were isolated from rhesus monkey testicular tissue for single-cell RNA sequencing, with results validated via immunocytochemistry and qPCR.
