There is a two-way connection between the pregnant woman and her unborn child. The fetus gets its nourishment through the placenta, receiving nutrients and oxygen. However, the latest research conducted by the American scientists showed that the cells of an unborn baby moved in the opposite direction, passing through the mother’s body to her brain. In addition, the DNA of a male baby can remain in the body of the mother for a few decades after the birth.
The scientists have discovered a gene in the body of women that is present only in the Y chromosome of the stronger sex. A group of experts at the Fred Hutchinson Cancer Research Center, led by William Chan, reported the presence of the cells of a male fetus in the mother’s body in 63% of the surveyed women. Moreover, the researchers were able to conclude about the benefits of male cells that were present not only in the brain, but also in the blood, lungs, heart, liver and other organs of the women.
This phenomenon is called microchimerism. It is considered that the DNA of a son can boost women’s immunity to fight against breast cancer. The benefits of the influence of a “fresh” cell on the mother’s body include its efficiency in treating rheumatoid arthritis and acceleration of damaged tissues repair. Also, the scientists believe that the male DNA is able to prevent the development of Alzheimer’s disease. However, there is an opposite tendency. Microchimerism may cause an autoimmune disease, and it is associated with the high risk of intestinal infections and skin cancer.
