Pregnancy can leave a cellular souvenir.
Fetal cells can persist in the mother's body for decades.
Here's the strange part.
Pregnancy can leave more than memories. Fetal cells can enter the mother's body and persist for decades, a phenomenon explored in studies of microchimerism. One reported observation involved bone marrow 51 years after a pregnancy. That does not establish persistence in every mother, and tracing a cell's origin can be complicated. Biology is less tidy than a family tree. (Cell Adhesion & Migration (PMC))
Persistence is not established for every mother or forever. The 51-year observation in this review concerned bone marrow, not brain tissue.
