非人灵长类动物是我们的近亲,因此为人类进化研究和生物医学研究提供了有价值的比较模型。因此,日本猕猴(Macaca fuscata)在野外和实验室环境中为灵长类动物学的进步做出了贡献。具体而言,日本猕猴作为一个很好的模型,调查出生后的发展和季节性繁殖的灵长类动物,因为他们的相对较长的少年期和独特的季节性繁殖活动在成年。开创性的组织学研究已经通过形态学观察研究了它们的生殖状态和精子发生之间的发育关联。然而,日本猕猴精子发生的分子组织学图谱仅处于起步阶段,限制了我们对与其生殖变化相关的精子发生个体发育的理解。在这里,我们进行了日本猕猴睾丸精子发生的免疫荧光分析,以确定一个子集的标记蛋白的表达。目前的分子组织学分析很容易将主要的精原细胞亚型指定为SALL 4 +A精原细胞和Ki 67 +/C-KIT+B精原细胞。DAZL、SCP 1、γ H2 AX、VASA和calmegin的表达进一步显示了在精子发生过程中以分化阶段特异性方式的蛋白表达谱和染色体结构的顺序变化。因此,亚成体和成体之间的比较分析确定了亚成体睾丸的分化和同步化的生精缺陷。我们的研究结果提供了一个新的诊断平台,解剖生精状态和生殖的日本猕猴。
Non-human primates are our closest relatives and therefore offer valuable comparative models for human evolutionary studies and biomedical research. As such, Japanese macaques (Macaca fuscata) have contributed to the advancement of primatology in both field and laboratory settings. Specifically, Japanese macaques serve as an excellent model for investigating postnatal development and seasonal breeding in primates because of their relatively prolonged juvenile period and distinct seasonal breeding activity in adulthood. Pioneering histological studies have examined the developmental associations between their reproductive states and spermatogenesis by morphological observation. However, a molecular histological atlas of Japanese macaque spermatogenesis is only in its infancy, limiting our understanding of spermatogenesis ontogeny related to their reproductive changes. Here, we performed immunofluorescence analyses of spermatogenesis in Japanese macaque testes to determine the expression of a subset of marker proteins. The present molecular histological analyses readily specified major spermatogonial subtypes as SALL4+A spermatogonia and Ki67+/C-KIT+B spermatogonia. The expression of DAZL, SCP1, γH2AX, VASA, and calmegin further showed sequential changes regarding the protein expression profile and chromosomal structures during spermatogenesis in a differentiation stage-specific manner. Accordingly, comparative analyses between subadults and adults identified spermatogenic deficits in differentiation and synchronization in subadult testes. Our findings provide a new diagnostic platform for dissecting spermatogenic status and reproduction in the Japanese macaques.
