| Research Abstract |
We investigated the role of the adipose tissue-derived stem cells(ADSC) in replacing growth of hepatoccellar carcinoma(HCC). HCC cell line(HuH7) and ADSC were co-cultured with or without cell-cell contact to clarify whether mediator affected HCC cell growth. And we concluded cell contact was important process in cell growth during co-culture HCC cells with ADSC. In addition, immunohistochemical staining of stemness marker(CD44 and CD133) and junction protein(Connexin 32) was performed in eleven well differentiated HCC patients with replacing growth. No positive cells were recognized in the invasive front area, however, junction protein(Cx32) was expressed at peripheral area in cytoplasm.
