Developmental Potential Studies on the Second Polar Body of Mouse

小鼠第二极体发育潜力研究

Near the area through which the first polar body was extruded , the microvillus of oocyte disappeared , where the second polar body might possibly be extruded .

排出极体处的细胞膜微绒毛消失，其下方是中期纺锤体，此区域可能为第二极体的释放部位。

By 55 min after the insemination , the second polar body was released .

第二极体排出的时间约在授精后55分钟。

Effects of Two-step First and Second Polar Body Biopsy on Fertilization of Oocyte and Embryo Viability in a Mouse Model

两步极体活检对小鼠卵母细胞体外受精和胚胎发育的影响

After fertilization membrane was lifted , the secondary egg emitted the second polar body into the perivitelline space .

受精膜举起后，由次级卵母细胞排放出第二极体。

Triploidy of Crassostrea gigas induced with 6-DMAP : by blocking the second polar body of the

6-DMAP诱导太平洋牡蛎三倍体&抑制受精卵第二极体释放

The release time of first polar body , second polar body and the start time of first cleavage about Haliotis diversicolor aquatilis 's oosperm are related to the water temperature .

九孔鲍受精卵的第一极体、第二极体以及第一次卵裂的出现时间与水温有关。

This study was made to optimize hydrostatic pressure shock conditions for producing triploid transparent colored crucian carp ( Carassius auratus transparent colored variety ) by inducing second polar body retention .

采用静水压休克方法研究了促使第二极体保留诱发三倍体水晶彩鲫的最佳条件。

By the 25-30th minute postinsemination , the first polar body was ejected . By 55 min after the insemination , the second polar body was released .

25～30min排出第一极体；第二极体排出的时间约在授精后55分钟。

After artificial fertilization , the first and second polar body was released from the egg . The blastula was formed by spiral cleavage . The gastrula , which was formed by invagination , was hatched at 24h pf ( post-fertilization ) .

单环刺螠虫受精后卵子先后排放第一、二极体，经螺旋型卵裂后生成腔囊胚，囊胚经内陷形成原肠胚，胚体于受精后24h孵化，形成担轮幼虫。

When the oocytes were fertilized in vitro , the microvilli on their surface became erect , the second polar body had a nucleus , and in the cytoplasm of the oocytes there were abundant organelles which were mainly distributed in the centre of the c ells .

受精后卵母细胞表面的微绒毛由倒伏而竖起，第二极体有核，细胞质中细胞器丰富，主要分布于细胞中心。
