From Church Life Journal:
Microchimeric cells have been found in various maternal tissues and organs, such as the breast, bone marrow, skin, liver and brain. Early and late effects of these cells have been hypothesized. Some of these cells appear to target sites of injury and may help mother heal after delivery by integrating into the Cesarean section wound and helping to produce collagen. Fetal cells may be involved in the process of lactation by signaling the mother’s body to make milk. Others have been thought to help protect a mother against breast cancer later in life. This process likely involves negotiation and cooperation between mom and baby at the cellular level. Researchers are in the early stages of attempting to understand the full function of these cells, but some models suggest that some of these cells continue to aid the mother years after her baby is born and may even influence spacing of future siblings. There is increasing evidence that fetomaternal microchimerism persists lifelong in many childbearing women and may have important implications for the immune status of women. Some studies suggest that fetal cells protect women against autoimmune disorders. The full significance of fetomaternal microchimerism remains unclear and in some studies the cells have been linked to higher rates of diseases. The reality of this process challenges our long standing ideas about human beings existing as singular autonomous individuals.Share
Human beings carry remnants of other humans in their bodies. This process is bidirectional, as you would expect in a relationship. Male cells may occur in the blood of as many as 8-10% of healthy women without sons and no history of abortion or pregnancy loss. This may be the result of a phenomenon called “the vanishing male twin” or could be the cells that entered her mother’s circulation from a previously carried male child, and then entered her own circulation. Identical twins exchange these cells through their shared placenta. The end result of these processes is that many of us are interconnected at the cellular level. What is truly amazing is that these cells are not inert. It would be one thing to have the cells from another person in your body and for them to do nothing. But it is another thing entirely that these cells become integrated into maternal tissue and are active and working in ways that we are just beginning to understand. This is radical mutuality at the cellular level. Think about mothers who have lost both prenatal and postnatal children, and how they have longed for their children still to be with them in some way, and now we see that they are in fact. What we can deduce from this mother-child cellular interconnectedness? We can say that Mary not only carried the Son of God in her body when he was in her womb, but that she likely carried his cells in her body throughout her life in a way that further magnifies her position as the glorious Theotokos.
