這些結果表明，外源鈣流入導致的胞質ca ~ （ 2 + ）濃度的升高，有促進卵細胞細胞壁快速形成的作用；而且，卵細胞對ca ~ （ 2 + ）信號的反應與發育狀態有關，可能僅成熟的未受精的卵細胞處於一種特殊的「感受態」 ，能對ca ~ （ 2 + ）信號發生反應而快速形成細胞壁。In a similar experiment, however, we succeeded in prompting human eggs ? on their own, with no sperm to fertilize them ? to develop parthenogenetically into blastocysts
但在另一個類似的實驗，我們卻能讓卵子在未經受精作用下，成功以孤雌生殖的方式發育到囊胚期。Researchers have identified a protein in women that destroys unfertilized eggs with genetic damage, an important step in discovering how to treat infertility, according to a study in the journal nature
