Androgen action via testicular arteriole smooth muscle cells is important for leydig cell function, vasomotion and testicular fluid dynamics [PDF]

, 2010
Regulation of blood flow through the testicular microvasculature by vasomotion is thought to be important for normal testis function as it regulates interstitial fluid (IF) dynamics which is an important intra-testicular transport medium.

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Immunophenotypic assessment of pure embryonal carcinoma and yolk sac tumour suggests that reprogramming to non‐seminoma occurs outside the spermatogonial niche

Histopathology, Volume 89, Issue 2, Page 303-311, August 2026.
Immunohistochemical analysis of transcription factors in GCNIS associated with pure EC and YST suggests that reprogramming to non‐seminoma occurs outside the spermatogonial niche. In these tumors, reprogramming may occur immediately upon invasion of the stroma or within seminiferous tubules but outside the spermatogonial niche (i.e., in intratubular ...

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, Volume 13, Issue 37, 3 July 2026.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Spermatogonial stem cells and in vitro spermatogenesis [PDF]

Reproductive Medicine and Biology, 2011
AbstractSpermatogonial stem cells (SSCs) provide the basis for the life‐long production of enormous numbers of sperm. The nature of these mysterious cells is being clarified. Although they were regarded to be mostly dormant, dividing rarely and remaining static in a niche, their rather dynamic behavior in the seminiferous tubules has been disclosed ...

Expression profiling of stemness markers in testicular germline stem cells from neonatal and adult Swiss albino mice during their transdifferentiation in vitro

Stem Cell Research & Therapy
Background Spermatogonial stem cells (SSCs) were considered to be stem cells with limited potencies due to their existence in adult organisms. However, the production of spermatogonial stem cell colonies with broader differentiation capabilities in ...

De Novo Genome Assemblies of Four Rainbow Trout Genetic Lines Reveal Structural Variants in Pursuit of a Pangenome Reference

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Rainbow trout (Oncorhynchus mykiss) exhibit extensive genomic diversity shaped by domestication, life history and geographic origin. To advance the development of a comprehensive pangenome reference, we present new de novo genome assemblies of two genetically and ecologically distinct lines: Whale Rock (WR; wild, landlocked, Central California)

Spermatogonial stem cells as a source for regenerative medicine

Middle East Fertility Society Journal, 2012
Several researchers have reported the derivation of multipotent cells from both mouse and human spermatogonial stem cells. These spermatogonia-derived stem cells show similarities with embryonic stem cells both for phenotype and functionality, indicating

The nature and dynamics of spermatogonial stem cells [PDF]

Development, 2017
Spermatogonial stem cells (SSCs) are crucial for maintaining spermatogenesis throughout life, and understanding how these cells function has important implications for understanding male infertility. Recently, various populations of cells harbouring stem cell-like properties have been identified in rodent seminiferous tubules, but deciphering how these
