On December 24, reporters learned from the Institute of Zoology, Chinese Academy of Sciences that researchers Yu Leqian and Wang Hongmei from the institute, in collaboration with domestic and international research teams, have successfully developed a 3D embryo implantation model based on microfluidic chips, known as the 3D uterus simulation chip. This model has, for the first time, fully replicated the human embryo implantation process in a laboratory environment. The related research findings were published in the international academic journal Cell on December 23. The study points out that among patients receiving assisted reproductive technology treatments in China, approximately 10% still fail to achieve clinical pregnancy after undergoing three or more embryo transfers, falling into the dilemma of repeated implantation failure. This represents a major challenge in the field of assisted reproduction. The development of this technology aids in identifying the core causes of repeated implantation failure, screening personalized effective drugs, and simplifying the testing process.
