I learned a long time ago that a little bit of every baby one carries in pregnancy stays in the mother as some of that baby’s cells. Was reminded of that recently by a Medium notifications of an essay by an adoptee, Mindy Stern LINK>My Dead Mother and Me, (which I couldn’t actually read much of because I am no longer a Medium member) and went looking for more. I found this – LINK>Fetal Maternal Microchimerism. This phenomenon gets its name from the chimera, a creature you might have heard of in Greek mythology that was part goat, lion, and dragon, hence the image I selected for today. Fetal Maternal Microchimerism explains situations where a mother’s body contains stem cells from her child in her body for years after childbirth.
Stem cells are the building blocks of life. They’re found in our body’s tissues, blood, organs, and immune systems. Once in the body, they use chemical cues from neighboring cells to grow into the same material as their surroundings. What makes them so unique is their ability to help repair or replace damaged or diseased cells within the body. Because of this innate ability, they can treat various medical conditions such as blood disorders, cancers, and immunodeficiencies. You may surrender your baby to strangers to raise in what is referred to as adoption but bits of that baby will be with you always.
When a woman is pregnant, she experiences placental immune suppression, which keeps the body from viewing the baby as an “intruder.” Scientists believe this occurrence allows for microchimerism because it will allow the fetus’ cells to sneak past the mother’s immune defenses without being marked as foreign. Since this immune suppression can remain for several months after delivery, there is ample time for the fetal cells to establish themselves and become a part of the mother’s body. Women do not produce Y chromosomes, yet research findings suggest that the Y chromosomes come from the cells of their sons being transmitted during pregnancy (blogger’s note – which interests me as I have given birth to 2 sons). Scientists have found fetal cells in scar tissues, specifically scars left by C-sections. It is theorized that these cells from the baby help the mom recover after birth by repairing wounds (blogger’s note – both of my sons were delivered C-section).
Both child and mother benefit from this exchange of fetal cells. The mutual desire to survive requires cooperation from both mother and baby. The baby’s innate desire to survive is prominent long before birth. Looking out for their mother’s health ensures the baby can develop safely. Science is proving that there is a very deep fetal-maternal bond. With my sons, I know I influenced their taste in food and, beyond my heartbeat and voice, my emotional energy enveloped them in utero. A newborn is not a blank slate, where it can be assumed the gestating mother can be easily replaced. The relationship between a mother and her child goes far beyond the nine months of pregnancy. Maybe someday, we will no longer separate the two of them, as is currently encouraged by governmental pro-adoption policies.
