MICROTUBULES IN THE SPERMATIDS OF THE DOMESTIC FOWL [PDF]

Journal of Cell Biology, 1967
Spermiogenesis in chicken has been examined in order to see whether the radical changes observed in cell shape can be related to the presence of cytoplasmic microtubules. A highly ordered array of tubules has been found which surrounds the nucleus as it elongates from a sphere to a slender cylinder.

ATAD2 deficiency leads to subfertility by impairing spermatogenesis in mice [PDF]

The Journal of Reproduction and Development
During spermatogenesis, chromatin remodeling regulated by histone modification is essential for spermatogenic cell development, and multiple epigenetic regulators are involved in this process.

Deciphering the role of Hat1 in spermatogenesis: Chromatin organization and beyond [PDF]

PeerJ
Spermatogenesis, a core process for male fertility, relies heavily on chromatin organization regulated by histone acetyltransferases (HATs). However, the spatiotemporal expression pattern of histone acetyltransferase 1 (Hat1) in mouse testes and its ...

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

Biology, 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

Cells, 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

Biology, 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

Journal 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

Reproductive 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

Laboratory 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]

Journal 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.
