A 2015 study suggested that this happens in almost all pregnant women, at least temporarily. Human microchimeras are produced when fetal stem cells or maternal cells cross the placenta (fetal-maternal microchimerism) or following blood transfusion (transfusion-associated microchimerism) or organ transplantation.
