You have stem cells from each of your babies in your brain

The physical and emotional link between a mother and her child is about as close as a relationship can be. New research now shows the physical connection is even deeper than anyone previously thought.

Stem cells from the fetus have now been found in many areas of the mother’s brain, heart and other organs. These stem cells are ‘pluripotent’ that is, they can potentially be induced to form many different cells lines such as brain or cardiac tissue and help in regeneration.

Another study illustrated their potential. The heart of pregnant animals were damaged by blockage of a coronary artery, simulating a severe heart attack, though this was not lethal. Later after the animals delivered, the heart was examined. Stem cells from their fetus had migrated to the damaged mother’s heart and helped it repair itself.

These cells from each and every one of your children are there, in your brain and heart…. for life. And they will all still be there when you die.

    Thank you for this article! I was adopted 62 years ago to a wonderful family~ but there is something in this article that even increases my respect for my birth mother. I have spent my professional career as an RN, giving stem cells and bone marrow infusions MURBMT to many a kid-0 and this makes it all even have greater significance in my heart and mind! Full circle of LOVE! Thank You, thank you –

    This is very interesting! I read something the other day – I wonder if there is a connection (link has references)

    “Pregnancy after onset of MS is associated with a longer duration until wheelchair dependence develops compared to never pregnant women or those who had children only before onset of the disease, and less risk of conversion to secondary progressive MS…An Australian study found that the risk of women developing MS halves with each child born, and is not affected by time since last birth, suggesting that the protective effect is due to pregnancy and is lifelong.”

    This is fascinating. As a mother of a child with a disability due to a genetic chromosomal abnormality, I wonder about any potential health implications this may have for me?

    Isn’t in Ephesians where Paul ? says if women continue in childbearing they will be saved?? I always wonder what in the world that could mean….could this be what it means??

    Beth that was my first thought as well. My daughter is missing a piece of her 22nd chromosome. I would LOVE to spend time researching this topic. Fascinating.

    Thanks Ivana….I’m trying not to over think it til we know more what’s going on with Connor!This article was very informative.

    this does not surprise me So happy to know the science behind the feeling.

    What a beautiful finding! It is no wonder that we mom’s have the unbreakable bonds with our babies that we do. There is scientific proof behind it!!

    I wonder if our children carry or stem cells and it we carry our kids stem cells do they pass on to subsequent siblings too?

      A mother donates her stem cells to her babies through her breastmilk!

    As a mother of loss to adoption, separated for 40 yrs, reading this article gives me leverage to explain the mother and baby separated physically due to adoption, I believe IS ALWAYS CONNECTED, I believe the umbilical link is what kept me going in the darkest of times, I also had felt my baby visit my conscience, there I would soul talk to my baby, and feel we had connected through conscience.The umbilical link never severs, the Mother of Loss to Adoption will have a measure of comfort and validation as MOTHER, and not birth-mother.

    There’s all sorts of amazing research on how fetal cells persist in the mother’s body, even cells from babies who were miscarried before the mother knew she was pregnant. For decades after a pregnancy, fetal cells rush to the site of injury or illness in the mother’s body to help heal her. The studies on this have extraordinary implications. Here’s more on that research:

      I was wondering at what point the stem cells transferred as I had a miscarriage with my first pregnancy and its somehow comforting to know I carry a piece of that little one with me. Thanks for sharing this article!!!

        Probably quite early in the pregnancy – though we have no definite evidence for that

    Kind of sentimental to me. My son passed away last year and it’s kinda nice to know that I could still be physically carrying part of him with me.

    Maybe why multiples (twins for example) ate also so connected. I wonder if they share each others stem cells as well?
