Hum Reprod Update:化学和物理因素对IVF的影响远甚于培养基配方

2015-12-20 candy 译 MedSci原创

背景:虽然实验室程序与培养基配方在过去的二十几年里已经有了改善,但是人类IVF仍然需要在体外进行(字面上为“在试管里”)。方法:检索PubMed数据库,使用化学和物理因素的列表作为关键词,无时间限制。如关键词包括:氧气、铵、挥发性有机物、温度、PH、油覆盖和潜伏期的体积/胚胎密度。将围绕物理和化学因素的可用的临床和科学证据进行评估,并呈现与此。结果和结论:体外胚胎的不断发展意味它将不仅仅暴露在存在

背景:虽然实验室程序与培养基配方在过去的二十几年里已经有了改善,但是人类IVF仍然需要在体外进行(字面上为“在试管里”)。

方法:检索PubMed数据库,使用化学和物理因素的列表作为关键词,无时间限制。如关键词包括:氧气、铵、挥发性有机物、温度、PH、油覆盖和潜伏期的体积/胚胎密度。将围绕物理和化学因素的可用的临床和科学证据进行评估,并呈现与此。

结果和结论:体外胚胎的不断发展意味它将不仅仅暴露在存在于体内环境的因子。人胚胎来源包括已经认可的影响因子如PH、温度、环境中氧气的暴露(20%)和由于自然培养的静态积聚在媒介中的毒素。然而,还有其他影响来源没有被考虑到,比如移液行为本身,或从胚胎培养的特殊组织培养器中释放的有机物。未来,当更多的影响因子出现在实验室中,就可作为最终在负协同效应的证据,因其最终将会对胚胎培养造成重大的损伤。这是胚胎对其微环境中的化学和物理信号敏感的证据,而且这些因子在影响胚胎发育和移植过程中扮演了十分重要的角色。


从辅助人类生殖的角度看,对化学和物理因子的主要关注点在于他们对胚胎存活率的副作用,以及对胎儿的长期影响,甚至是相对短暂曝光后的结局。此次综述旨在化学和物理影子对于哺乳动物胚胎的副作用和对此识别的重要性,从而最大程度减少这些影响因子在人类IVF中的影响。因此,优化体外环境的成分远远比提高培养基配方更重要。
