在试管婴儿的治疗过程中,胚胎发育是一个动态的过程,经历了受精、卵裂、囊胚形成三个阶段,需要6 ~ 7天,受精的标志是雌雄原核的出现,称为合子,当雌雄原核融合在一起时,标志着受精过程的完成,但是很多人不太明白什么是胚胎原核,所以下面这篇文章就详细介绍一下什么是胚胎原核。
体外胚胎的临床评价从原核观察开始,主要观察内容包括原核和核仁的特征,主要观察原核的数量、大小和相互位置,以及核仁的数量、排列和对称性,原核的形态、核仁的大小和排列、细胞质的出现等形态特征与胚胎发育、着床率和妊娠率有关,原核观察期为精卵共孵育后16 ~ 18小时,双原核的出现提示受精正常,原核的发育速度和对称性与胚胎的发育潜能有关。
什么是胚胎原核
胚胎原核也指原核细胞的核质体,是精子进入卵子后的配子,排卵后,卵子进入输卵管壶腹部,当获能精子与卵子的透明带结合时,受精就开始了,受精在输卵管壶腹部需要24小时左右,此时的受精卵称为原核胚胎。
当精子进入卵母细胞时,精子形成雄性原核,卵子形成雌性原核,两个原核携带来自双亲的遗传物质,逐渐靠拢形成两个原核的合子,也叫受精卵,这个阶段的受精卵自然会在输卵管内逐渐融合,然后进行有丝分裂和增殖,形成卵裂期和囊胚。
Tips:原核胚是指体外受精后16 ~ 18小时观察到受精卵有两个原核胚,对于一些重复胚胎评分低,没有胚胎可移植的患者,可以尝试原核胚胎移植,但需要注意的是,原核胚胎移植并不是一种通用策略,并不适用于每一位患者,而是针对反复无胚胎可移植的患者的一种试验策略。
