The maturation of cortisone-treated embryonic duodenum in vitro. I. The villus.
M I T O T I C expansion of the mucosa coupled with contraction of intrinsic longitudinal and circular muscle fibers produces previllous ridges on the luminal surface of the embryonic chick duodenum by the thirteenth day of incubation. Subsequently, remodelling by periodic indentation of the mucosal surface yields primitive villi which expand and elongate to form the tall, finger-like projection...
متن کاملP-109: Using SMAD2/3 Inhibitor to Investigate the Importance of GDF9 Signaling on Ovine Cumulus Expansion and Subsequent Embryonic Development
Background: Oocyte in vitro maturation success rate is still low in compareision to oocyte in vivo maturation. Thus prediction and improvement of oocyte competency are two critical issues in assisted reproductive technology. New insights into oocyte-cumulus cell regulatory loop may assist our optimization of in vitro maturation technique. Maturation and developmental competency of cumulus oocyt...
متن کاملEffects of Crocin Supplementation during In Vitro Maturation of Mouse Oocytes on Glutathione Synthesis and Cytoplasmic Maturation
Objective Crocin is an active ingredient of saffron (Crocus sativus L.) and its antioxidant properties have been previously investigated. This carotenoid scavenges free radicals and stimulates glutathione (GSH) synthesis; consequently, it may protect cells against oxidative stress. The aim of this research is to protect oocytes from oxidative stress by the addition of a natural source antioxida...
متن کاملEffect of Ethanol on Maturation and Development of Immatur Mouse Oocytes
Purpose: To study the effect of ethanol on resumption of meiosis, maturation and development of immature mouse oocytes in vitro. Materials and Methods: Immature oocytes were dissected from ovary of NMRI strain mouse (6-8 weeks old) and divided into control and experimental groups. The absolute ethanol was imposed to oocytes at doses of 0 (Control), 0.05, 0.1, 0.2 and 0.4% (v/v) in maturation c...
متن کاملP-28: The Effect of Hydrostatic Pressure on the In vitro Maturation of Preantral Follicles Derived from Polycystic Ovaries in Mouse Model
Background: Polycystic ovary syndrome (PCOS) is a multifactorial, heterogeneous, complex genetic endocrine and metabolic disorder, diagnostically characterized by chronic anovulation, polycystic ovaries and biochemical and clinical manifestations of hyperandrogenism. In patients with PCOS lower apoptotic rates found in granulosa cells compared to women with regular ovulatory cycles and this lea...
