Other therapeutic options are limited by the characteristics of ameloblastoma, such as high recurrence rates and resistance to radiation and chemotherapy, which implies possible existence of cancer stem cells (CSCs) in ameloblastoma. Here, we identified a putative CSC population in immortalized and primary human ameloblastoma cells and examined possible therapeutic reagents to reduce the CSC population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We investigated subpopulations of AM<jats:bold>\u2010<\/jats:bold>1 cell line and human ameloblastoma cells using immunocytochemistry and flow cytometry and the effects of Wnt signalling activators on the 2<jats:bold>\u2010<\/jats:bold> and 3<jats:bold>\u2010<\/jats:bold>dimensional cultured ameloblastoma cells using molecular biological analyses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Result<\/jats:title><jats:p>Among heterogenous ameloblastoma cells, small<jats:bold>\u2010<\/jats:bold>sized and round<jats:bold>\u2010<\/jats:bold>shaped cells were found to be proliferative and expressed a marker of dental epithelial stem cells, SRY<jats:bold>\u2010<\/jats:bold>box 2 (Sox2). Exogenous activation of Wnt signalling using glycogen synthase kinase 3\u03b2 inhibitors, lithium chloride (LiCl) and valproic acid (VPA), increased the cell size and decreased proliferation of cells and expression of Sox2 in 2 dimensionally cultured AM<jats:bold>\u2010<\/jats:bold>1 and human primary ameloblastoma cells. Furthermore, the growth of 3 dimensionally cultured AM<jats:bold>\u2010<\/jats:bold>1 cells as suspended or embedded in gel was suppressed by treatment with Wnt signalling activators, VPA and
