Scientists have just sowed the human fetus on the camera

Simulation made it possible to estimate how the human fetus not only adheres to the lining of the uterus, but it is actively included in itself. “We note that the fetus is withdrawn on the uterine matrix, and moves and reorganized it,” explained by Amili Godot, composed of research, which was published in Science progress.

These movements can explain pain some women reports after days of fertilization. “Although it is known that many women suffer from abdominal pain and mild bleeding during the transplant, the process itself has not been noticed before,” said Augusngerus.

Different types, different tactics

The researchers also compared to transplantation of human embryos and mouse embryos. They found that mouse embryos are planting themselves by extending the surface of the uterus, while human embryos can firmly include themselves in any direction, including lower endometrium. The comparison confirms that each type has developed its own tactics to achieve transplantation.

Moreover, when applying external mechanical stimuli to fetuses, the researchers noticed that they responded to these, but in different ways. Human embryos have recruited myosin, a protein that contributes to regulating muscle contraction, and re -directed some of their protrusions, while mouse embryos have adjusted the direction of the body axis towards the source of strength. These results show that the embryos are not negative receptors, but rather imagine an activity responded to the external mechanical signals received during the transplant.

Understanding mechanical forces involved in the transplant provides new search opportunities: it can master a certain method for choosing embryos and treating them in auxiliary production programs. The next clear step is to explore the mechanical causes of infertility, as well as those already known as genetic.

The human embryos used in this research were provided by Dexeus Mujer Barcelona, which is the Women’s Health Specialized Clinic, gynecology, and reproductive medicine. “Our work has consisted of providing technical advice and choosing the human embryos that have been donated to research, ensuring the ideal conditions of the project,” said Mikel Souli, Director of Dexeus Mujer Cryopreservation Laboratory.
