Scientists capture first footage of human embryo implanting in a uterus | Science

A human embryo implanted in a uterus was depicted by a scientist team for the first time in real -time and 3D images.

It shows the images of a synthetic uterus implanted embryo and shows how the process naturally occurs.

The groundbreaking images were published by researchers at the Catalonia Institute (IBEC) in cooperation with the Dexeus University Hospital in Barcelona, which donates embryos.

Samuel Ojosnegros, İBEC’s chief researcher Bioengineering for the reproductive health group And the chief author of the study said that the study was important because the application process revealed how detailed.

“We have observed that human embryos have entered the uterus and apply a significant force throughout the process, Oj said Ojosnegros. “These forces are necessary, because the embryos should be able to invade the uterine tissue and become completely integrated. This is a surprisingly invasive process. Although many women experienced abdominal pain and slight bleeding during implantation, the process itself has not been observed before.”

Embryo implantation occurs when a fertilized egg is connected to the lining of the uterus about six to 12 days after ovulation.

It was developed by a platform researchers who allow embryos to implanate outside the uterus under controlled conditions. This platform, which is partially based with collagen and uterine tissue, then provided analysis of real -time fluorescent imaging and interactions with the environment of the embryo.

After that, the researchers conducted experiments with human and mouse embryos to compare two implantation processes. As a mouse sticks to the surface of the embryo, they discovered that a human embryo completely penetrated into the uterine tissue before growing from the inside.

The study also showed that during the implantation process, the human embryo released the enzymes that disrupt the surrounding tissue and that this embryer applied traction around it.

The failure of the implantation process is one of the main causes of infertility, which constitutes approximately 60% of miscarriages. According to the researchers, this study, which helps to understand the implantation process, may have a significant impact on fertility rates.

Amélie Godeau, the first author and the first author of the study, said, “We observe that the embryo has pulled, moves and rearranged the uterus matrix. He also reacts to external force clues. in vivo It may affect embryo implantation. “
