"Maternal cells may remain in the brain for life" — New Scientist · Science & Medicine
This refers to maternal , a phenomenon where cells from a mother cross the during pregnancy and integrate into the developing fetus's tissues, including the brain. A new study reported by New Scientist suggests that these maternal cells can persist in the brain for a person's entire lifetime, potentially taking on specialized roles like neurons or immune cells. The finding adds to growing evidence that mother-child cellular exchange is more extensive and long-lasting than previously understood.
The claim is based on a peer-reviewed study (likely published in a scientific journal) and reported by New Scientist, a reputable secondary source. The reporting appears to closely follow the primary research, and multiple other outlets (e.g., Live Science) have covered similar findings from July 2026, lending consistency to the claim.
The New Scientist article was published on October 13, 2026, making it genuinely new reporting on this specific study, though the underlying phenomenon of maternal microchimerism has been studied for decades.
