研究了超排处理注射 h CG后不同时间猪卵丘卵母细胞复合体 (COC)的回收率和形态、卵母细胞减数分裂进程以及 COC形态与生发泡 (GV)染色质构型之间的关系。
2.
Even though COCs were strictly selected before in vitro culture, the chromatin configuration of dictyate stage oocytes was different.
实验结果表明： 1 采用活体荧光染料Hoechst 33342对山羊生发泡进行观察，根据染色质构型及核仁大小将其分为8种形态：GV0、GV1、GV2(GV2-1、GV2-2)、GV3(GV3-1、GV3-2)GV4和GVBD。
3.
There are more evidence show that variouse stage of antral follicular oocyte before maturation culture in vitro, first reflected on the chromatin configuration of the nucleus , may account for the observed flaw of in vitro maturation system.
目前越来越多的证据表明，体外成熟培养前卵泡卵母细胞发育阶段的差异可能是卵母细胞体外成熟系统不完善的原因之一，这首先反映在未成熟卵母细胞核染色质构型就存在差别。
2) chromatin organization

X染色质
生理名。亦 称Barr小体、X小体及巴氏小体。可见于人、哺乳类、鸟类、爬行类、两栖类及昆虫的雌体 细 胞核内。其在间期细胞核中，呈异固缩状态，染色深而密集。在显微镜下为一1～15μm之 浓染 小体。位置贴近核膜内面。具脱氧核糖核酸性质，对弗兰根反应阳性。用H·E染色、硫磺染 色均呈浓紫蓝色。用甲基绿-派朗宁混合剂可染成绿色。Guard的猩红快绿染色法染为红 色(常染色体呈绿色)。可作为人类性别鉴定及诊断性染色体异常的指标。
