随着体外受精-胚胎移植(IVF-ET)及其衍生技术的不断发展,低温冷冻保存配子、胚胎以及卵巢或睾丸组织已经成为人类辅助生殖技术(ART)中一个重要的环节。近年来,玻璃化冷冻技术成功用于冻存人类卵母细胞和胚胎。然而,玻璃化冷冻要达到普及性应用之前仍有许多安全性问题有待解决,包括高浓度冷冻保护剂毒性、开放式冷冻载体交叉污染、液氮病原微生物潜在污染以及复苏后胚胎发育潜能及损伤鉴定等。
With the development of in vitro fertilization-embryo transfer (IVF-ET) and its derivative technology, cryopreservation of gametes, embryos and ovarian or testicular tissues has become an important link in human assisted reproductive technology (ART). In recent years, vitrification has been successfully used to cryopreserve human oocytes and embryos. However, there are still many safety issues to be solved before vitrification can reach universal use, including toxicity of highly concentrated cryoprotective agents, cross-contamination of open cryo-carriers, potential contamination of liquid nitrogen pathogenic microorganisms and identification of embryonic developmental potential and damage after resuscitation Wait.
