@thecurioustales @grok is there peer reviewed research on the above claims?

[Grok @grok]

Yes anchetov, extensive peer-reviewed research confirms fetal microchimerism. Fetal cells persist in maternal tissues (heart, brain, thyroid) for decades—e.g., Bianchi et al. (1996 PNAS) detected them up to 27+ years postpartum, with studies finding them in women in their 90s from pregnancies 60+ years prior. They migrate to injury sites and aid repair (heart models in mice/humans). Pregnancy triggers lasting gray matter reorganization (Pritschet et al. 2024 Nature Neurosci), tied to social/empathy adaptations. Cells transfer even after miscarriage/abortion. Key reviews: O'Donoghue (2008), Fjeldstad (2020) in PMC.

[Grok @grok]

Yes, the science on fetal microchimerism is well-supported. Fetal cells cross the placenta, persist for decades (even 60+ years) in maternal organs like heart, brain, and thyroid, and can migrate to injury sites to aid repair. Pregnancy loss transfers them too. Brain studies (e.g., Nature Neuroscience) show lasting gray matter reorganization in social/empathy areas, aiding maternal adaptation. The "forever bond" has a real cellular basis.

[Saint John Lateran @StJohnLateran]

@thecurioustales Microchimerism has theological implications: Mary is New Ark of the Covenant *even after the Birth of Christ* – for the living cells of the God-Man remain within her. And when her heart is pierced by the sword (Luke 2:35) during the Passion of Christ, their sufferings are linked.

[The Curious Tales @thecurioustales]

The science of fetal microchimerism should have broken the internet by now.

It hasn’t.

When I read about a research I was so curious to know what’s actually happening.

Fetal cells — carrying the child’s own DNA — cross into the mother’s bloodstream during pregnancy and never fully leave. They embed into her organs. Her heart muscle. Her brain tissue.

Researchers have found a child’s living cells inside mothers in their 90s, from pregnancies six decades old. The child left the womb. The cells didn’t.

And they don’t just sit there. They migrate toward damage. Women with heart injuries show fetal cells concentrated at the wound site. Women with thyroid disease show their children’s cells inside the affected tissue.

The body that built the child gets tended to, in return, by the child’s own cells. Nobody designed this consciously. Evolution quietly built a repair system out of the mother-child bond itself.

The brain side of this is equally staggering. Pregnancy triggers gray matter reorganization — a structural rewiring that sharpens threat detection, deepens empathy, fundamentally alters how a mother processes the world. These changes persist for years after birth.

Possibly permanently. A mother’s nervous system doesn’t return to its factory settings. It was updated by the experience of carrying another person, and that update sticks.

The part worth sitting with longest — women who experienced pregnancy loss carry fetal cells too. The cellular merging doesn’t require a birth. It doesn’t require years of raising someone. Those cells remain regardless of what happened after. A mother grieving a child she never brought home is grieving someone biologically still present inside her. The world consistently underestimates that grief. The science says we have no business doing that.

Mothers always knew the connection didn’t end at birth.

Turns out it doesn’t end at the cellular level either.

@jamie_raskin Happy Birthday!

@GovofCO Remember when comments were decent and often beneficial? I used to follow the comments from the advanced science minds who often discussed climate change. I’m not a hard science person, so it was interesting, and I was learning from them.

[LynnTweets🌻 @LDRTweets2021]

@chefjoseandres @KayeSteinsapir @WCKitchen I hope you, too, are well cared for Chef Andres. May God bless you abundantly.

@GovPressOffice It’s interesting to read the responses. What stands out is the concrete thinking of Trump supporters as opposed to abstract thinkers supporting GN. If I were a betting person, I’d wager these thinking style differences are consistent nationally.

Social Security became law 90 years ago today. Here's what we need to do to keep the vital program strong for another 90 years (and beyond).

@RpsAgainstTrump @mccaffreyr3 I sure hope that this era instills a profound, multigenerational demand for honor and integrity in gvt . It’s all so disgusting. How did we get to a place where this behavior is just ignored/dismissed?
