The oldest woman to have fetal cells in her brain was 94 years old, suggesting that these cells can sometimes stay in the body for a lifetime.Abbate, Cheryl. They found that 63 percent of these women had traces of male DNA from fetal cells in their brains. In a 2012 study, researchers analyzed the brains of 59 women ages 32 to 101, after the women had died. In some cases, fetal cells may stay in a woman's body for years. The researchers knew that the cells were from the fetus, and not from the mother, because the cells contained a Y chromosome (found only in males) and all of the women had been carrying sons. The study found that the women had fetal cells in all of these tissues. The researchers tested tissue samples from the kidneys, livers, spleens, lungs, hearts and brains of 26 women who died while pregnant or within one month of giving birth. This can happen when a woman becomes pregnant and a small number of cells from the fetus migrate into her blood and travel to different organs.Ī 2015 study suggested that this happens in almost all pregnant women, at least temporarily. More commonly, people may exhibit so-called microchimerism - when a small fraction of their cells are from someone else. A blood transfusion will also temporarily give a person cells from someone else, but in a bone marrow transplant, the new blood cells are permanent, according to the Tech Museum of Innovation in San Jose, California. But in other cases, recipients may have a mix of both their own blood cells and donor ones, according to a 2004 review paper (opens in new tab) in the journal Bone Marrow Transplantation. In some cases, all of the blood cells in a person who received a bone marrow transplant will match the DNA of the donor.
