A dynamic transcriptional cell atlas of testes development after birth in Hu sheep.

ABSTRACT:

Background

Testes development is a fundamental process in sexual development and reproduction. The testes undergo dramatic structural changes during development, including the proliferation and differentiation of somatic cells such as Sertoli cells, Leydig cells, and myoid cells, as well as the maturation of spermatogonia. However, little is known about the onset of spermatogenesis and cell proliferation and maturation in the spermatogonial niche in large animals.

Results

We used single-cell RNA sequencing (scRNA-seq) to profile nearly 100,000 cells from Hu sheep testes across seven developmental stages (birth, prepuberty, puberty, and adulthood). We constructed single-cell transcriptomic atlases and identified distinct spermatogonial subtypes, revealing dynamic gene express
