背景情况:

精子宏相关3蛋白 (SAMP3) 对于受精至关重要.
卵巢表达SAMP3可能会影响女性的生殖能力.
卵巢SAMP3表达的与年龄相关的变化尚未得到充分理解.

研究的目的:

量化SAMP3蛋白表达在年轻和成年女王的卵巢.
为了比较不同年龄组之间的不同卵巢卵泡阶段和细胞组件之间的SAMP3表达.

主要方法:

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...
