项目摘要
To enable improved success rate of IVF, we developed the technology to optimize embryo selection, having the highest implantation potential while ensuring no damage to embryos using zona elasticity as selection criteria. First, "zona hardening" was demonstrated mechanically following fertilization at the PN stage, Young's modulus decreased gradually as the embryo developed. Evaluation of the quality of expanded blastocysts(EPB) shows that the quality of EPBs could also be evaluated from elasticity parameters. Furthermore observations indicated that ZPs of embryos generated in vivo were significantly harder than those of embryos generated in vitro at each stage. We examined the correlations between subsequent ZP elasticity changes after IVF treatment and quality of embryos and the results showed that the pregnancy rate after MTS-eSET was almost the same with that after double-embryo transfer. It was also examined that both theoretically and experimentally the MTS test does not cause any damage to embryos. Furthermore, we developed a cryo-nano-hole vitrification container with a low concentration of CPA solution with no serum and mouse and human blastocysts can be cryopreserved successfully.
为了提高体外受精的成功率,我们开发了优化胚胎选择的技术,以透明带弹性作为选择标准,在确保胚胎不受损的同时,具有最高的植入潜力。首先,在PN阶段受精后机械地证明了“透明带硬化”,杨氏模量随着胚胎发育而逐渐下降。对膨胀囊胚(EPB)质量的评价表明,EPB的质量也可以从弹性参数来评价。进一步观察表明,体内产生的胚胎的ZP在每个阶段都明显比体外产生的胚胎更硬。我们检查了IVF治疗后ZP弹性变化与胚胎质量之间的相关性,结果显示MTS-eSET后的妊娠率与双胚胎移植后的妊娠率几乎相同。还检查了理论上和实验上MTS测试不会对胚胎造成任何损害。此外,我们还开发了一种低浓度CPA溶液、无血清的冷冻纳米孔玻璃化容器,可以成功冷冻保存小鼠和人类囊胚。
