Journey from fetus to Mother
Posted on 29th June 2018

It's not surprising that cells can be easily exchanged between mother and fetus, said Amy Boddy, a biologist at the University of California, Santa Barbara. That's because humans have one of the most invasive placenta types among mammals — one that rearranges arteries so that there is direct blood flow between the mother and the fetus.
This cell exchange starts about six weeks into a pregnancy and continues for the duration, Boddy told Live Science.
Studies have found that these fetal cells can essentially travel to anywhere in the body. In a 2015 study, researchers found cells that contained Y chromosomes in the brains, hearts, kidneys, lungs, spleens and livers of 26 women who died within one month after pregnancy (all were carrying male babies).
The fact that they can be found in so many different tissue types indicates that they're probably stem cells, or cells that can differentiate into any type of cell, she said. (Indeed, the fetal cells also carry markers on their surfaces that are typical stem cells, she added.)
The mother's body kills off most of these circulating fetal cells shortly after pregnancy. But some evade the immune system and can stay for long periods of time in the mother's body — in some cases, even a lifetime, she said.
"If [the cells were] integrated into tissue … they can be around for a lifetime," Boddy said. For example, a 2012 study found  Y chromosomes in 63 percent of the brains of 59 women— the oldest of whom was 94. That means these weren't women who just gave birth.

My advise
1...  It is memorable journey of every mother
2..   In pregnancy a bond developed between the fetus to mother will be for ever
3...  Give healthy food to your fetus
