Apoptosis occurs at any time in the ontogeny of the testis, especially during the first wave of
spermatogenesis. However, the exact mechanisms by which homeostasis of apoptosis and …

In the mammalian testis, spermatogenesis is a highly coordinated process of germ cell
development, which ends with the release of 'mature'spermatozoa. The fine regulation of …

Background The availability of a unique unselected Holstein line since 1964 provided a
direct comparison between selected and unselected Holstein genomes whereas large …

BACKGROUND: Several important functions for a successful spermatogenesis are
dependent on Sertoli cells (SCs). Besides their unique characteristics as support cells, they …

Estrogens, through their receptors, play an important role in regulation of spermatogenesis.
However, the precise role of the estrogen receptors (ESR1 and ESR2) has been difficult to …

Objective To study the effect of estrogens regulating the testicular expression of stem cell
factor (SCF) and c-kit. Design Experimental study. Setting University research center. Animal …

Apoptosis is an important regulatory event in testicular homeostasis and optimization of
sperm production. Sertoli cells (SCs) form the blood–testis barrier creating a special …

Regucalcin (RGN) is a calcium (Ca2+)-binding protein which plays an important role in the
regulation of Ca2+ homeostasis and has been shown to catalyse an important step in l …

The process of reproductive in domestic livestock is one of the most important challenges of
animal husbandry. Fertility is an important trait that contributes to herd profitability, and it can …

The role of estrogens in male reproductive physiology has been intensively studied over the
last few years. Yet, the involvement of their specific receptors has long been a matter of …
