“The thing about microchimerism…”

I’ll assume that some of you have never heard of microchimerism.  I had not till just a few years ago and I’m what many might call somewhat chronologically mature.  

So what exactly is it?

In pregnancy, women are shape-shifters, their bellies waxing like the moon. After delivery, they hold RaulHernandezGonzalezanother kind of magic: microchimerism, a condition in which women harbor cells that originated in their children even decades after birth.
The name, born from Greek myth, refers to the chimera, a fire-breathing lioness with the head of a goat rising up from her body and the tail of a serpent. In ancient mythology, the chimera was an omen of storms and natural disasters. Just what microchimerism foretells still isn’t clear, but a recent study in the International Journal of Epidemiology suggests that these cells may substantially improve the health of the women who house them.

These fetal cells migrate all over a mother’s body, becoming part of the heart, the brain, and blood—and fascinating scientist and artists alike.

Do read the rest because not only is it fascinating, it forms a scientific basis for a particular dogma of the Catholic Church, one celebrated tomorrow.

That basis explained by Elizabeth Scalia:

As marvelous as it was to learn about how “wonderfully and fearfully” we are made — what with blood cells forming and fading, and bones and tissue becoming oxygenated and cleansed via blood and breath — nothing presented in the class coaxed an audible reaction from me until we studied the process of microchimerism. As soon as the professor introduced the process, my Catholic bell was rung: “But that completely explains the Assumption!” I said aloud in the midst of my startled classmates. The professor stared at me for a moment with a puzzled expression and said, “Oka-a-ay, anyway, the thing about microchimerism…” The thing about microchimerism is that it so profoundly explains and justifies our dogma that it should be included in our Mariological catechesis, where people can both appreciate a demonstration of how science and religion can complement and complete each other, and marvel in awestruck wonder that our Church had reasoned out this reality long ago and without the aid of microscopes. In the simplest of terms, microchimerism is the process by which a smattering of cells live within a host body but are completely distinct from it. In human fetomaternal microchimerism (or “fetal cell microchimerism”), every child leaves within his mother a microscopic bit of himself — every pregnancy, brought to delivery or not, leaves a small amount of its own cells within the body of the mother — and those cells remain within her forever.
As the only practicing Catholic in the classroom mentioned above, can you blame me for my gratified outburst? Microchimerism explained for me the very whys and wherefores of a dogma that had previously seemed like little more than piety on a sentimental rampage, leaving me too cowed to care. Suddenly, it all made sense: A small amount of Christ Jesus’ cells remained within Mary, for the whole of her life. Where we Catholics have a limited experience of Christ’s flesh commingling within our own upon reception of the holy Eucharist, Mary was a true tabernacle within which the Divinity did continually reside.
In the Book of Psalms we read about how the Holy One will not undergo corruption (see 16:10). Christ’s divine body did not undergo corruption. It follows that His mother’s body, containing cellular traces of the Divinity (and a particle of God is God, entire) could not be permitted to decay, either. The science makes the theology accessible, because, suddenly, there is no need for guessing: at her Dormition, Our Lady’s body, holding Christ within it, could not remain on earth; of course, it would have to join itself to Christ in the heavenly dimension.
One could argue that microchimerism also assists in our understanding of the Immaculate Conception — once again, it gives the patina of science to a long-held, and very beautiful, dogma. The God who is All Good is also Purely God; the vessel through which He incarnated, then, must necessarily be pure. When we argue that Mary, as the Ark of the New Covenant, would have been spared the stain of original sin, the knowledge that Christ not only availed himself of her flesh, but would continually reside therein, only further supports that well-reasoned belief. Every August, since learning about the awesome scientific validation of a perhaps underappreciated dogma, I have at some point in the feast day found myself singing a line from Paul Simon: “I would not give you false hope / On this strange and mournful day / When the mother and child reunion / Is only a motion away.”
I love it when faith and reason can be woven together into such a beautiful whole.

A beautiful whole indeed.

It may not convince you to think differently about Mary the Mother of God and our beloved Mother but it will educate you as to why we who are Catholic do.

Carry on.

    Excellent articles – I recommend reading it all.

    In a more profane vein from Rick and Elizabeth Scalia, this jumped out from the Atlantic article:

    A 2004 study found the presence of male genes in 21 percent of women overall—even among those who had only given birth to daughters, had a miscarriage, underwent an abortion, or had never been pregnant. Researchers speculate the unknown DNA could have come from a miscarriage these women never recognized, or from an older brother who transferred cells to their mother, who in turn passed the genes onto subsequent children. Or—here’s where the science starts to feel like sci-fi—women could have picked it up through sexual intercourse, traces of past lovers never lost.,

    So if you fuck a girl, she might have your DNA in her for the rest of her life, maybe giving her strength?

    The other thing that came to mind is the research on toxoplasmosis, through which cats take advange of proxy controlling of the minds of mice that lose their fear of cats and thus get eaten, and people that become cat slaves.
