Scientists Just Caught Human Embryo Implantation on Camera

The simulation made it possible to praise how a human fetus not only adhered to the uterus lining, but actively insert itself. “We noticed that the embryo was drawn to the uterus matrix, it was running and reconstructing,” the research assistant Amelie Gadau explained, which was published The progress of scienceThe

These movements may explain the pain of reporting some women a few days after the fertilization. “Although it is known that many women experience abdominal pain and light bleeding during planting, the process itself has never been seen before,” Ozosegros said.

Different species, different techniques

Researchers also compared human embryos and mouse fetal transplants. They found that the mouse fetuses plant themselves on the surface of the womb, where human embryos can embed themselves in any direction, including the uterus lining. The comparison implies that each species developed its own techniques to acquire planting.

Furthermore, researchers observed that they both responded to it, but in different ways. Human embryos appointed Mayocin, a protein that contributes to the control of muscle contraction and reinstates some of their protrusions, while the mouse fetus adjusts the orientation of their body to the source of the ball. These searches prove that the fetus is not a passive receptor, but also actively realize the external mechanical signals during the planting and react.

The mechanical forces involved in planting provide new opportunities for research: A specific Avenue is to perfect the selection and treatment of the fetus in the support-reconciliation programs. Another obvious next step is to explore mechanical causes of infertility, besides people already known as genetic.

The human fetus used in this study provided Dexiece Muzar Barcelona, ​​a female health clinic that specialized in processes, gynecology and reproductive medicine. “Our job is to provide technical advice and to the human fetus strictly selected for research, confirming that they have met the ideal conditions of this project,” said Mikel Soli, director of the Dexius Mazer Creopageration Laboratory.
