The natural cervical relaxation which occurs at estrus in the ewe may be initiated by binding
of hyaluronan (HA) to its receptor CD44. Indeed, we have previously shown that HA content …

The complex anatomy of the ovine cervix limits the success of trans-cervical artificial
insemination in sheep. However, there is a degree of natural relaxation of cervix at oestrus …

Hyaluronan (HA) has been related to fertilization and embryo development in the pig.
Furthermore, HA is present in pig oviduct fluid and the lining epithelium, particularly of the …

In preparation for birth, the uterine cervix undergoes a remarkable transformation from a
closed, rigid structure to a distensible, remodeled configuration that stretches to allow …

In this study, we investigated steroid regulation of the hyaluronan (HA) system in ovine
endometrium including HA synthases (HAS), hyaluronidases, and HA receptor-CD44 using …

Artificial insemination (AI) using frozen semen is a key method to enable rapid genetic
improvement but its use in the sheep industry is currently limited by poor fertility …

We examined the expression pattern of hyaluronan synthase (HAS) mRNAs in the uterine
cervix of pregnant mice. The expression levels of HAS-1 and-2 mRNAs peaked at delivery …

In response to the gonadotropin surge, the compact cumulus-oocyte complex (COC)
undergoes expansion by synthesis of the mucopolysaccharide hyaluronan (HA) …

In contrast to other species, the preovulatory rise in gonadotropins in mares causes a
remarkable expansion of the entire granulosa cell layer in vivo, suggesting that hyaluronan …

OBJECTIVE: To quantify and study the immunoexpression of hyaluronic acid (HA) in the
uterine horns of the mouse throughout the estrous cycle phases. DESIGN: Experimental …
