During pregnancy, cells can move between a mother and her baby — and some can remain in the body for decades. This process is called microchimerism. Research has found that fetal cells can cross into the mother’s bloodstream during pregnancy and may persist in different tissues long after birth. Scientists are still studying what these cells do. Some research suggests they may be involved in tissue repair and immune responses, while other studies are exploring possible links to certain health conditions. The shocking truth? Pregnancy can leave behind a biological connection between mother and child that lasts far beyond birth. #ScienceFacts #HumanBiology #PregnancyScience #Genetics
