過熟卵泡 的英文怎麼說
中文拼音 [guòshúluǎnpāo]
過熟卵泡
英文
postmature follicle-
Protein kinase a is camp - dependent kinase, one of the most important signal transduction pathways, plays a pivotal role in growth, differentiation, tumor occur, cell cycle control, etc. pka activators such as camp, 8 - br - camp or phosphodiesterase ( pde ) inhibitor isomethyl butyl xanthine ( imbx ) or purified pka catalytic subunit all can inhibit germinal vesicle breakdown ( gvbd ) and meiotic maturation in mouse oocytes, also in xenopus oocytes
蛋白激酶a （ proteinkinasea ， pka ）是依賴于camp的絲蘇氨酸蛋白激酶，是重要的信號傳導途徑之一，廣泛參與許多生命過程，包括生長、分化、腫瘤發生、細胞凋亡、細胞周期調控等。以小鼠卵母細胞為實驗對象，給予pka激動劑camp 、 8 - br - camp或磷酸二酯酶抑制劑imbx （ isomethylbutylxanthine ）均可抑制小鼠卵母細胞的胚泡破裂及減數分裂成熟。Techniques in embryo technology ( such as in vitro production of embryos and animal cloning ) need large quantities of high quality oocytes. but the quality of in vitro matured oocytes from slaughtered animals is generally lower than that of the in vivo matured oocytes. it is usually thought that the reason for this poor quality in in vitro matured oocytes is the lack of capacitation during the dominancy of follicular development in vivo
目前胚胎工程技術研究和開發（如體外生產胚胎和體細胞克隆等）需要大量高質量的成熟卵母細胞，但利用屠宰動物卵巢卵母細胞經過體外成熟培養而獲取的卵母細胞質量還遠不如體內成熟卵母細胞，其原因一般認為是由於缺乏體內主卵泡階段的獲能作用。However, the oocytes will arrest the first meiosis at prophase in their follicles. after a long development and acquiring the meiotic resumption competence, oocytes in preovulatory follicles will resume meiosis to mature under the stimulation of preovulatory gonadotropins surge
卵母細胞減數分裂隨之停滯于第一次減數分裂的前期，在卵泡中通過漫長的生長發育過程后，在一定的刺激條件下才恢復減數分裂而成熟。The improvement of culture condition of ivm is essential to achieve better outcome of ivm. during the development of follicles, granulosa cells proliferate and differentiate under fsh control. granulosa cells mediate fsh control on oocyte maturation and secrete several factors to maintain an appropriate rnicroenvironment for oocytes to mature
卵泡是一個結構和功能單位，其中顆粒細胞是卵泡內主要的體細胞成分，它介導促性腺激素對卵母細胞的調節，同時通過自分泌或旁分泌作用，維持有利於卵母細胞成熟的微環境。分享友人
