Aneuploidy is relatively common in mammalian preimplantation embryos, due to chromosome segregation errors in mitosis. A new paper in Development investigates whether the mitotic timer mechanism, a checkpoint that detects prolonged M phase, which may indicate an unhealthy cell division, is active in preimplantation mouse embryos. We caught up with first author Adélaïde Allais and corresponding author Greg FitzHarris (Professor at the Université de Montréal) to find out more about their research.
非整倍体在哺乳动物的胚胎中比较常见,这是由于有丝分裂中染色体分离错误造成的。《发育》杂志上的一篇新论文研究了有丝分裂定时器机制(一种检测 M 期延长的检查点,这可能表明细胞分裂不健康)是否在着床前的小鼠胚胎中活跃。我们采访了第一作者阿黛拉伊德·阿莱(Adélaïde Allais)和通讯作者格雷格·菲茨哈里斯(Greg FitzHarris,蒙特利尔大学教授),以了解更多关于他们的研究。
