"During pregnancy, some baby cells migrate into the mother's bloodstream and then return to the child. It's called "mother-fetal microchimerism."
For 41 weeks, the cells mix and circulate back and forth, and, after the baby is born, many of these cells remain in the mother’s body, leaving a permanent imprint in the tissues, bones, brain and skin of the baby to mother, and they often remain there for decades.
Every other child a mother has will leave a similar imprint on her body.
Even if a pregnancy doesn’t end, or if you have an abortion, these cells still migrate into the bloodstream.
Research has shown that if a mother’s heart is injured, fetal cells will rush to the injury site, and transform into different types of cells that specialize in repairing the heart.
The child helps the mother repair, while the mother builds the child.
This is often the reason why some diseases fade away during pregnancy.
It's amazing how the mother's body protects the baby at all costs, and the baby protects and rebuilds the mother in return, so they can safely develop and survive.
The study also showed the presence of fetal cells in a mother's brain 18 years after birth.
How wonderful is this?"
