Cryopreservation and transplantation of common carp spermatogonia - Fig 1

, 2019
Optimization of the freezing (A-D) and vitrification (E, F) protocols for common carp spermatogonia. (A) Viability of spermatogonia after freezing with dimethyl sulfoxide (Me2SO), ethylene glycol (EG), glycerol (Gly), Me2SO and propylene glycol at ratio ...

Effect of FSH on testicular morphology and spermatogenesis in gonadotrophin-deficient hypogonadal mice lacking androgen receptors [PDF]

, 2010
Follicle stimulating hormone (FSH) and androgen act to stimulate and maintain spermatogenesis. FSH acts directly on the Sertoli cells to stimulate germ cell number and acts indirectly to increase androgen production by the Leydig cells.

Renewal of Spermatogonia in the Monkey (Macaca Fascilularis) [PDF]

Biology of Reproduction, 1986
Populations of different types of spermatogonia and their mitotic activity were analyzed in the monkey Macaca fascicularis: 3 adults aged 5-6 yr and 3 young aged 2-3 mo. Two young and two adult monkeys received injections of 3H-thymidine for radioautographic study of the relationships between Type A spermatogonia: dark Type A (Ad), pale Type A (Ap) and

Use of Clotrimazole in Finfish Aquaculture: Mechanistic Insights, Limitations, and Future Directions for Antifungal Therapy

Animal Research and One Health, EarlyView.
This review critically evaluates clotrimazole as a potential antifungal for finfish aquaculture, highlighting strong mechanistic and in vitro efficacy against aquatic mycoses alongside major gaps in in vivo evidence, toxicokinetics, residue safety, and environmental risk, outlining priorities for responsible therapeutic development and regulatory ...

Distribution of GFRA1-expressing spermatogonia in adult mouse testis

, 2012
In mice and other mammals, spermatogenesis is maintained by spermatogonial stem cells (SSCs), a cell population belonging to undifferentiated type A spermatogonia.

Loss of TSLC1 causes male infertility due to a defect at the spermatid stage of spermatogenesis. [PDF]

, 2006
Tumor suppressor of lung cancer 1 (TSLC1), also known as SgIGSF, IGSF4, and SynCAM, is strongly expressed in spermatogenic cells undergoing the early and late phases of spermatogenesis (spermatogonia to zygotene spermatocytes and elongating spermatids to

Heat stress in spermatogenesis: a redox‐dependent decision network linking ROS, autophagy, and regulated cell death

Biological Reviews, EarlyView.
ABSTRACT Heat stress (HS) is an increasing threat to male reproductive health, disrupting spermatogenesis through complex and interdependent cellular responses within the seminiferous epithelium. Although excessive reactive oxygen species (ROS) production is a hallmark of HS, ROS also act as central regulators of cell fate decisions beyond their role ...

Stem Cell Defects in ATM-Deficient Undifferentiated Spermatogonia through DNA Damage-Induced Cell-Cycle Arrest [PDF]

, 2008
SummaryMammalian spermatogenesis is maintained by stem cell capacity within undifferentiated spermatogonial subpopulation. Here, using a combination of surface markers, we describe a purification method for undifferentiated spermatogonia. Flow cytometric

Potential Neuroendocrine Disruption by Benzodiazepines and Its Impact on Male Fertility

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neuroactive substances have emerged as potent endocrine disruptors affecting male reproductive health through central and peripheral mechanisms. Among these, benzodiazepines, which are widely used for the management of anxiety, insomnia, epilepsy, and neuromuscular disorders, are known as GABA A (gamma‐aminobutyric acid type A) receptor ...

Transcriptome analysis of differentiating spermatogonia stimulated with kit ligand [PDF]

, 2008
Kit ligand (KL) is a survival factor and a mitogenic stimulus for differentiating spermatogonia. However, it is not known whether KL also plays a role in the differentiative events that lead to meiotic entry of these cells.
