From the research we've done, the main risk is that doing this produces chromosomal damage in at least half, if not 70 per cent, of eggs.
从我们的研究了解到，主要的风险来自对卵细胞染色体的破坏，就算没有70%至少也有一半多。
Several factors, such as defects in chromosome segregation and DNA damage response, failure of cell cycle checkpoint, telomere dysfunction, may cause chromosomal instability.
多种细胞机制功能障碍将导致染色体不稳定性，包括染色体分离、DNA损伤反应、细胞周期检查点、端粒功能等。
