Distinct roles of two myosins in C. elegans spermatid differentiation

open access: yesPLoS Biology, 2019
During spermatogenesis, interconnected haploid spermatids segregate undesired cellular contents into residual bodies (RBs) before detaching from RBs. It is unclear how this differentiation process is controlled to produce individual spermatids or motile ...

Establishment of a Coilia nasus Spermatogonial Stem Cell Line Capable of Spermatogenesis In Vitro

open access: yesBiology, 2023
The process by which spermatogonial stem cells (SSCs) continuously go through mitosis, meiosis, and differentiation to produce gametes that transmit genetic information is known as spermatogenesis.

Zbtb40 Deficiency Leads to Morphological and Phenotypic Abnormalities of Spermatocytes and Spermatozoa and Causes Male Infertility

open access: yesCells, 2023
Studies on the gene regulation of spermatogenesis are of unusual significance for maintaining male reproduction and treating male infertility. Here, we have demonstrated, for the first time, that a loss of ZBTB40 function leads to abnormalities in the ...

Establishment of a Coilia nasus Gonadal Somatic Cell Line Capable of Sperm Induction In Vitro

open access: yesBiology, 2022
Coilia nasus is an important economic anadromous migratory fish of the Yangtze River in China. In recent years, overfishing and the deterioration of the ecological environment almost led to the extinction of the wild resources of C.nasus.

Recent Advances in Elongated and Round Spermatid Injection

open access: yesJournal of Urological Surgery, 2021
Azoospermia is commonly identified in patients with infertility. Non-obstructive azoospermia (NOA) includes primary or secondary and incomplete testicular failure. Before testicular sperm extraction (TESE), donor insemination is the only option available

The Spin1 interactor, Spindoc, is dispensable for meiotic division, but essential for haploid spermatid development in mice

open access: yesReproductive Biology and Endocrinology, 2021
In mammals, germline development undergoes dramatic morphological and molecular changes and is epigenetically subject to intricate yet exquisite regulation.

Immunohistochemical localization of glucose transporter 1 and 3 in the scrotal and abdominal testes of a dog

open access: yesLaboratory Animal Research, 2017
Glucose is essential for testicular function; the uptake of carbohydrate-derived glucose by cells is mediated by glucose transporters (GLUTs). In the present study, we investigated the activity of GLUT1 and GLUT3, the two main isoforms of GLUTs found in ...

Differentiation-related changes in lipid classes with long-chain and very long-chain polyenoic fatty acids in rat spermatogenic cells[S]

open access: yesJournal of Lipid Research, 2010
In rat seminiferous tubules (ST), cells that contain polar and neutral lipids with long-chain polyenoic fatty acids (PUFA) and sphingomyelins (SM) and ceramides (Cer) with very long chain (VLC) PUFA of the n-6 series coexist.

Reprogramming of round spermatids by the germinal vesicle cytoplasm in mice. [PDF]

open access: yesPLoS ONE, 2013
The birthrate following round spermatid injection (ROSI) remains low in current and evidence suggests that factors in the germinal vesicle (GV) cytoplasm and certain substances in the GV such as the nucleolus might be responsible for genomic ...

Ultrastructural investigation and in vitro recapitulation of spermatid differentiation in a potential bio-indicator species - The marine invertebrate Galeolaria gemineoa (Polychaeta: Serpulidae). [PDF]

open access: yesPLoS ONE, 2017
Galeolaria gemineoa is a sessile broadcast-spawning marine invertebrate, whose spermatozoa have been regarded as a sensitive indicator for water quality monitoring.
