polar bodies

同根派生

The oocytes undergoing meiotic division sequentially extrude the first and the second small polar bodies from the large oocytes.
卵母細(xì)胞在減數(shù)分裂過程中相繼排出第一和第二極體。
Objective:To establish the method of preimplantation genetic diagnosis(PGD) by use of first polar bodies.
目的:建立采用第一極體植入前染色體非整倍體診斷的方法。
The studies indicated that Inhibiting formation of the first and the second polar bodies in normal diploid zygotes could produce living tetraploid pearl oysters .
比較研究表明，直接抑制二倍體馬氏珠母貝受精卵的極體形成可以獲得成活的四倍體馬氏珠母貝，此方法值得進一步研究。
Results:The successful biopsy and FISH rate were 94.7% and 86.7% respectively. 61.5% of the first polar bodies was found to be normal, 38.5% was aneuploidy.Conc...
結(jié)果:活檢成功率為94.;7%25;FISH成功率為86
The chromosomes within these polar bodies have the same genetic and reproductive poten cials as those left in the oocytes and can be used for production of fertile off spring.
這些極體內(nèi)的染色體和留在卵母細(xì)胞內(nèi)的染色體同樣具有遺傳和生殖潛力，可用作生產(chǎn)有生殖能力的后代。
