Cigarette smoke inhibits hamster oocyte pickup by increasing adhesion between the oocyte cumulus complex and oviductal cilia.
Previous research has shown that oocyte cumulus complex (OCC) pickup rate is inhibited in hamsters when oviducts and OCCs are simultaneously exposed to cigarette smoke solutions, independent of any effect on ciliary beat frequency. The purpose of this research was to determine whether smoke solutions caused a change in adhesion between the OCC and infundibulum of the oviduct and to determine wh...
متن کاملIn vitro analysis of oocyte cumulus complex pickup rate in the hamster Mesocricetus auratus.
In mammals, the oocyte and its surrounding cumulus cells constitute on oocyte cumulus complex (OCC). During ovulation, OCCs are extruded into the peritoneal or bursal cavity, depending on the species, and are then rapidly picked up by the fimbria on the outer surface of the oviductal infundibulum and transported to the ampulla, where fertilization occurs. We developed a method to measure OCC pi...
متن کاملAssay and importance of adhesive interaction between hamster (Mesocricetus auratus) oocyte-cumulus complexes and the oviductal epithelium.
Adhesion between the oocyte-cumulus complex and infundibulum plays an important, but poorly understood, role in oocyte pick-up. The purposes of this study were to determine which components of the oocyte-cumulus complex and oviductal epithelium function in adhesion, to measure adhesion under physiological conditions, and to examine the effect of modulation of adhesion on oocyte-cumulus complex ...
متن کاملExploring cumulus-oocyte-complex-oviductal cell interactions: gene profiling in the bovine oviduct.
Prostaglandin E(2) (PGE(2)) is present in the bovine oviduct and may play an important role in muscle contraction or as survival factor providing the optimal environment for fertilization and the early embryo. The aim of the present study was to investigate the estrous cycle-dependent changes and local distributions of PGE(2) receptors (EP) and members of the trefoil factor (TFF)-family in the ...
متن کاملP-110: Effect of Increasing Amount of Oocyte Secreted Factors on Cumulus Expansion of Bovine Cumulus-Oocyte Complexes
Background: In vitro maturation is a good method to decrease cancer risk of superovulation by gonadotropin hormones. A paracrine effect of oocyte secretions on oocyte developmental competence is under investigation. Apart from oocyte maturation, ovulation in vivo requires a precise control of extracellular matrix modification. Cumulus cells secrete hyaluronan to form a muco-elastic extracellula...
