中文摘要
项目总结:
体细胞核移植取代单倍体减数分裂中期染色体(MII)--受阻
来自体细胞的具有二倍体间期染色质的卵母细胞。这种SCNT卵母细胞是二倍体的,不适合
因三倍体而受精。然而,我们的初步研究表明,SCNT卵母细胞能够
形成由成对的单染色单体染色体组成的减数分裂早期纺锤体
激活或受精可以诱导体细胞染色体分离成假极体。我们的研究
将确定DNA能否诱导小鼠SCNT卵母细胞的体细胞同源配对和重组
双链断裂和开发未来治疗不孕不育的方法。
英文摘要
Project Summary:
Somatic cell nuclear transfer (SCNT) replaces haploid meiotic chromosomes in metaphase (MII)-arrested
oocytes with diploid interphase chromatin from somatic cells. Such SCNT oocytes are diploid and are not suitable
for fertilization due to triploidy. However, our preliminary studies indicate that SCNT oocytes are capable of
forming premature meiotic spindles consisting of paired single-chromatid chromosomes and subsequent
activation or fertilization can induce segregation of somatic chromosomes into a pseudo polar body. Our research
will determine if somatic homolog pairing and recombination in mouse SCNT oocytes can be induced by DNA
double strand breaks and develop future therapeutic approaches for infertility treatments.
