AIM: It is reasonable to assume that microchimerism could also be involved in the induction of primary biliary cirrhosis (PBC). However, previous reports investigated only fetus-microchimerism in women patients. Maternal microchimerism has not been investigated until now.The current study aimed to clear either maternal microchimerism was involved in the pathogenesis of PBC or not.METHODS: We used fluorescence in situ hybridization on paraffin-embedded tissue (We called "Tissue-FISH".) to determine whether maternal cells infiltrated in male patients who were diagnosed as having PBC. Tissue-FISH was performed by using both X and Y specific probes on the biopsy liver sample of 3 male PBC patients.RESULTS: Infiltrating lymphocytes demonstrated both X and Y signals in all 3 male patients.CONCLUSION: Maternal microchimerism dose not play a significant role in PBC. PBC may not relate to fetus and maternal microchimerism.
