Résumé
Objective To preliminarily screen the neoplastic stem cell (NSC) related surface markers combination and to under-stand the NSC distribution in hepatoblastoma(HB) .Methods The children cases of HB undergone the surgical therapy in the Jian-gxi Provincial Children′s Hospital were selected .The immunohistochemical method was adopted for observing the expression and distribution of NSC-related markers CD34 ,Thy-1 ,c-kit ,CD56 and stem cell factor(SCF) in the HB tissue and the normal hepatic tissue away from the edge of tumor tissue 3cm outside .Results Thy-1 and c-kit were sporadically distributed in the HB tissue and mainly focued on the portal area ,but did not exressed in the normal liver tissue ;the expression of CD34 and SCF in HB was signifi-cantly higher than that in the normal liver tissue(P0 .05) .Conclusion The different NSC related surface markers are distributed in the HB tissue and focus on the specific areas .The positive cells of Thy-1/c-kit expression may play a role in the HB occurrence .
