Chimerism is the presence of more than one genetically distinct population of cells in a single organism that originated from more than one zygote and microchimerism occurs when the non-host cells represent only yug<5% of the cells of an individual and can be a consequence of pregnancy, organ transplantation, and transfusion. Most of the microchimerism was observed during pregnancy. Microchimerism can be divided into two types: the cells that are transferred from the fetus to the mother, called fetal microchimerism cells (FMC), and the cells that are transferred from the mother to the fetus, called maternal microchimerism cells. Both cells can remain in the blood and tissues for decades or even their whole life. In humans, FMC is the most common form of microchimerism. In this mini-review, we are going to discuss in detail microchimerism and pregnancy.
