概括

女人的生育能力依赖于许多基因,但这项研究发现13种特定的卵巢丰富基因对小鼠的繁殖不必. 克里斯普尔/卡斯9基因编辑证实这些基因单独不会影响生育结果.

科学领域:

生殖生物学生殖生物学
遗传学是一个遗传学.
发展生物学发展生物学

背景情况:

在全球范围内,不孕症影响了六分之一的夫妇,女性因素导致了50%的病例.
超过150个基因在卵巢中高度表达,但它们在生育中的作用尚未完全理解.

研究的目的:

调查13个卵巢和/或卵细胞丰富基因在女性生育能力中的功能.
为了确定这些基因的个体淘汰是否会影响小鼠的生殖能力.

主要方法:

使用CRISPR/Cas9基因组编辑,为特定基因创建了13个单独的淘汰赛小鼠线.
进行了交配试验,以评估后代的生产.
卵巢组织学和体外受精是在选定的突变基因线上进行的.

主要成果:

所有13个突变小鼠系都成功地产生了后代.
在测试线条中,在卵巢发育或受精能力方面没有观察到任何显著的异常.
研究的13个基因在小鼠中对雌性生育不至关重要.

结论:

这项研究表明,13个特定的卵巢丰富基因对小鼠的雌性生育不至关重要.
这些发现有助于了解女性生殖和不孕不育的遗传基础.

Oogenesis

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
