Species like bears conceive early, so their cubs are born in the spring, when there are more opportunities to find food.stop buttonThey serve a function as “. This hibernation-like state, known to be used by more than 130 mammals, allows animals to delay the development of their offspring until a more appropriate time to adapt to their environment.
Now scientists have discovered a similar pause function. in human embryos They also announced what they discovered. The research results have been published in the journal Cell.
The molecule that helps delay pregnancies also works in humans
The team in Germany discovered that this feature, which we can describe as a pregnancy pause button, in human cells They discovered that it could work too. Molecular geneticist Nicolas Rivron used the following statements in his statement:
“Although we have naturally lost our hibernation-like abilities, these experiments show that we actually retain this ability within us and can eventually unleash it. “Inducing drowsiness during procedures such as in vitro fertilization may give the embryo more time to assess its health and better implant in the uterus.”
In this study, researchers discovered through laboratory experiments that the same molecule that allows other mammals to delay their pregnancy It also works on human stem cells and human embryos. They observed. “mToriThis molecule, called “, was discovered in mice in a study conducted in 2016.
The team exposed a blastoid, a stem cell model representing a five- to seven-day-old embryo, to mTori. The results showed that this blastoid was found in the laboratory. enters a hibernation-like phase that can last up to 8 days was seen coming in. When reactivated, the blastoids ‘awakened’ and develop normally continued. However, it has also been observed that more cells in human stem cells may die during the process than in mice. However, it is truly impressive that there was a developmental delay in the blastoid.
Of course, it is not entirely possible at this point to interrupt or delay human pregnancy at will. It’s just science fiction. However, experts believe their work could help understand this process, which occurs in most mammals, and help people with fertility problems in the years to come.
