Background. The presence of microchimerism in transplanted tissues is well defined; however, the timeframe of appearance and disappearance of engraftment in liver allograft is unknown. The aims of this study were to analyze for the presence of "recipient-derived cells" in sex-mismatched individuals after liver transplantation, comparing the frequency of "recipient-derived cell repopulation" in early versus late transplant biopsies and to evaluate the relationship between "recipient-derived cell repopulation" and the severity of graft injury.
