The Transcriptional Cell Atlas of Testis Development in Sheep at Pre-Sexual Maturity

open access: yesCurrent Issues in Molecular Biology, 2022
Sheep testes undergo a dramatic rate of development with structural changes during pre-sexual maturity, including the proliferation and maturation of somatic niche cells and the initiation of spermatogenesis.

Histological characterisation of gonadal sex differentiation in Malabar red snapper (Lutjanus malabaricus) for aquaculture advancement

open access: yesJournal of Fish Biology, EarlyView.
Abstract The Malabar red snapper (Lutjanus malabaricus) is a high‐value tropical marine species receiving growing attention for aquaculture development in Singapore and Southeast Asia. At present, seed production relies primarily on uncontrolled mass spawning in sea cages, a practice that lacks consistency, biosecurity and control of genetic ...

Sex‐Specific Gene Expression Ontogeny During Gonadal Development in Post‐Metamorphic Xenopus tropicalis

open access: yesMolecular Reproduction and Development, Volume 93, Issue 4, April 2026.
Post‐metamorphic gonadal development in Xenopus tropicalis was analyzed through integrated morphometric, histological, and transcriptional approaches. Males showed upregulation of cyp17, amh, and amhr2, whereas females exhibited an increased aldh1a2 and ddx4.

Single-cell transcriptome analyses reveal critical regulators of spermatogonial stem cell fate transitions

open access: yesBMC Genomics
Background Spermatogonial stem cells (SSCs) are the foundation cells for continual spermatogenesis and germline regeneration in mammals. SSC activities reside in the undifferentiated spermatogonial population, and currently, the molecular identities of ...

Single-cell transcriptome analysis and in vitro differentiation of testicular cells reveal novel insights into male sterility of the interspecific hybrid cattle-yak

open access: yesBMC Genomics, 2023
Background Interspecific hybridization plays vital roles in enriching animal diversity, while male hybrid sterility (MHS) of the offspring commonly suffered from spermatogenic arrest constitutes the postzygotic reproductive isolation.

IL1R2 Marks and Sorts a Spermatogonial Stem Cell Population Critical for Restoring Spermatogenesis Upon Interruption in Mammals

open access: yesAdvanced Science, Volume 13, Issue 13, 3 March 2026.
Spermatogonial stem cells (SSCs) provide critical support to spermatogenesis. Here, the author established Il1r2 as a sorting marker for SSCs, with which further insights into the SSC heterogeneity and dynamic features can be obtained. They also confirmed findings in both mouse and human, thus validating IL1R2 as the surface marker for isolating and ...

Spermatogonial stem cell quest: nanos2, marker of a sub-population of undifferentiated A spermatogonia in trout testis

open access: yes, 2014
Supplementary DataContinuous or cyclic production of spermatozoa throughout life in adult male vertebrate depends on a sub-population of undifferentiated germ cells acting as spermatogonial stem cells (SSCs).

Comparative Single‐Cell Transcriptomic Atlas Reveals the Genetic Regulation of Reproductive Traits

open access: yesAdvanced Science, Volume 13, Issue 17, 23 March 2026.
A cross‐species single‐cell transcriptomic atlas of reproductive and central nervous system tissues from sheep and humans reveals conserved cellular programs and regulatory networks that regulated fertility. Integration with GWAS for sheep lifetime average litter size identifies UNC5–SLIT–BMP signaling as a core pathway coordinating neuroendocrine ...

Isolation of THY1+ Undifferentiated Spermatogonia from Mouse Postnatal Testes Using Magnetic-activated Cell Sorting (MACS)

open access: yesBio-Protocol, 2016
In mammals, homeostasis of many tissues rely on a subpopulation of cells, referred to as stem cells, to sustain an appropriate number of undifferentiated and differentiated cells.
