Tubulin-based microtubule is a core component of flagella axoneme and essential for sperm motility and male fertility. Structural components of the axoneme have been well explored. However, how tubulin folding is regulated in sperm flagella formation is still largely unknown. Here, we report a g...
A significant anabolic response to loading was observed in static and dynamic microCT parameters as well as histomophometric measures of bone formation (Figs2–5). Subanalyses of each genotype showed that at the beginning of the experiment (day 0), there were no difference in static microCT p...
Study Uncovers Genetic Hierarchy In Plant Sperm Formation, May Meet The Demands Of Food Shortage And Food Price InflationDavid Twell
The surface distribution of flagella in peritrichous bacterial cells has been traditionally assumed to be random. Recently, the presence of a regular grid-
(with either sperm or egg) can result in infertility43,44. A three-dimensional (3D) cellular microenvironment has been shown to be crucial for the development of epithelial cells, as ciliated cells rapidly transform into flattened cells without cilia in a two-dimensional (2D) culture system45,...
Fertility in birds is dependent on their ability to store adequate populations of viable sperm for extended durations in sperm storage tubules (SSTs). The exact mechanisms by which sperm enter, reside, and egress from the SSTs are still controversial. Sh
limits inflammation and aids organogenesis9,10,29,30,31. Furthermore, the release of EVs containing healthy mitochondria from spermatid is also a critical process for normal sperm development32. Thus, the formation and removal of large EVs carrying organelles is an important mechanism that facilitates...
CATSPERS3, 4, CATSPERβ and CATSPERγ are expressed in testis, despite their absence in the principal piece of sperm cells in Cat- Sper1-null mice12, 13. In testis, they are present in the endoplasmic reticulum (ER) and the Golgi apparatus, as is typical for proteins during assembly....
The procedure of video selection is shown in Fig.1a. A total of 26,113 embryos from 2594 IVF and intracytoplasmic sperm injection (ICSI) cycles were cultured in TLM incubators from February 2014 to December 2017, and the women’s age at the retrieval cycles ranged from 20 to 50 years old...
Keywords: 8-oxoguanine (8-oxoG); acrosome; sperm; infertility; bull 1. Introduction In beef production in Korea, more than 90% of the beef is bred by artificial insemination (AI); therefore, the ability to predict the fertility of bulls before AI has been a long-term objective of the ...
