In December 1997, a fire broke out in Luz Cuevas's home in Philadelphia. Her daughter Delimar was just 10 days old. When the smoke cleared, officials told Cuevas her baby had passed in the blaze.

But something never sat right with her. No remains were ever found. The crib was empty, and the bedroom window had been left open on a freezing winter night. The fire officials had an explanation for everything, but Cuevas, a young mother who spoke little English, could not shake the feeling that her daughter was still alive somewhere.

For six years, no one believed her. The strain of the loss ended her relationship with Delimar's father. The world had closed the case. She had not.

Then, in early 2004, Cuevas was invited to a birthday party. Across the room she noticed a 6-year-old girl with dark hair and deep dimples, and her heart stopped. She was certain she was looking at her daughter.

She needed proof. So she walked over, told the little girl she had gum stuck in her hair, and quietly pulled five strands from her head. She folded them into a napkin and slipped them into a plastic bag. As she later put it, she had learned from television that hair was what you needed for DNA.

The test confirmed what her instinct had screamed for six years. The girl was Delimar.

She had been taken the night of the fire by a woman named Carolyn Correa, a distant relative by marriage, who had staged the blaze to cover the kidnapping and raised the child as her own, just 15 miles away. Correa was arrested, and Delimar was finally returned to her real mother.

🧬❤️ We've always been told about the emotional bond that exists between a mom and her baby, but it turns out biology takes this to a deeper level.

There's a process called fetal microchimerism, and I'll tell you what it's all about.

During pregnancy, the baby's stem cells cross the placenta and decide to stay and live in the mom's organs forever. In studies, scientists have found DNA from children (even children's Y chromosome) in the brains, lungs and hearts of women up to 70 years old.

And here's the part that surprises me even more, and it's what these cells do in moms bodies.

According to the article, they're not there for adornment. When a woman suffers a serious injury, such as damage to the heart, the child's cells automatically travel to the wound site and transform into new tissue to help heal it.

I can say that, years after giving birth, the mother has her children's living cells operating and repairing their bodies from the inside, which makes the emotional connection even deeper.

The whole process of microchimerism is documented in clinical research from the National Institutes of Health of the United States (NIH).

This is such a fascinating discovery! Does this change how you think about the maternal bond?
