Science has uncovered a breathtaking truth: a baby in the womb can act as its mother’s healer. During a heart attack, fetal stem cells are able to cross the placenta and migrate to the mother’s heart, where they help repair damaged tissue. This process, known as fetal microchimerism, shows how deeply connected the two lives really are.
Researchers have even found that some of these fetal cells stay in the mother’s body for decades, integrating into her organs and tissues. While the long-term effects are still being studied, this discovery highlights pregnancy not only as a miracle of life, but also as a powerful biological partnership that can protect both mother and child.
