SETDB1 Regulates Porcine Spermatogonial Adhesion and Proliferation through Modulating MMP3/10 Transcription

open access: yesCells, 2022
The transition from gonocytes into spermatogonia takes place during the homing process. A subpopulation of undifferentiated spermatogonia in niche then shifts to spermatogonial stem cells (SSCs), accompanied by the self-renewal ability to maintain life ...

Primate Primordial Germ Cells Acquire Transplantation Potential by Carnegie Stage 23. [PDF]

open access: yes, 2017
Primordial germ cells (PGCs) are the earliest embryonic progenitors in the germline. Correct formation of PGCs is critical to reproductive health as an adult.

MAFB is dispensable for the fetal testis morphogenesis and the maintenance of spermatogenesis in adult mice [PDF]

open access: yes, 2018
The transcription factor MAFB is an important regulator of the development and differentiation of various organs and tissues. Previous studies have shown that MAFB is expressed in embryonic and adult mouse testes and is expected to act as the downstream ...

Undifferentiated primate spermatogonia and their endocrine control [PDF]

open access: yesTrends in Endocrinology & Metabolism, 2010
The biology of spermatogonial stem cells is currently an area of intensive research and contemporary studies in primates are emerging. Quantitative regulation of sperm output by the primate testis seems to be exerted primarily on the transition from undifferentiated to differentiating spermatogonia.

Conservation of spermatogonial stem cell marker expression in undifferentiated felid spermatogonia [PDF]

open access: yesTheriogenology, 2016
Spermatogonial stem cells (SSCs) are distinct in their ability to self-renew, transmit genetic information, and persist throughout the life of an individual. These characteristics make SSCs a useful tool for addressing diverse challenges such as efficient transgenic production in nonrodent, biomedical animal models, or preservation of the male genome ...

Inhibin reduces spermatogonial numbers in testes of adult mice and chinese hamsters [PDF]

open access: yes, 1989
Bovine follicular fluid (bFF) injected ip in mice during 2 days (65,000 U inhibin/day, 1 U inhibin the activity in 1 /μg bFF protein) caused a significant decrease in the numbers of A4, intermediate (In), and B spermatogonia to 91%,74%, and 67% of the ...

A scRNA-seq Approach to Identifying Changes in Spermatogonial Stem Cell Gene Expression Following in vitro Culture

open access: yesFrontiers in Cell and Developmental Biology, 2022
Spermatogonial stem cell (SSC) function is essential for male fertility, and these cells hold potential therapeutic value spanning from human infertility treatments to wildlife conservation.

Spermatogonial kinetics in humans [PDF]

open access: yes, 2017
The human spermatogonial compartment is essential for daily production of millions of sperm. Despite this crucial role, the molecular signature, kinetic behavior and regulation of human spermatogonia are poorly understood.

Identification of a Crosstalk among TGR5, GLIS2, and TP53 Signaling Pathways in the Control of Undifferentiated Germ Cell Homeostasis and Chemoresistance

open access: yesAdvanced Science, 2022
Spermatogonial stem cells regenerate and maintain spermatogenesis throughout life, making testis a good model for studying stem cell biology. The effects of chemotherapy on fertility have been well‐documented previously.

Spermatogonial Gene Networks Selectively Couple to Glutathione and Pentose Phosphate Metabolism but Not Cysteine Biosynthesis

open access: yesiScience, 2021
Summary: In adult males, spermatogonia maintain lifelong spermatozoa production for oocyte fertilization. To understand spermatogonial metabolism we compared gene profiles in rat spermatogonia to publicly available mouse, monkey, and human spermatogonial
