There is indication that tumor growth is sustained by subpopulation of cells with stem-like features but little is known on their genomic characterization and their genetic stability. We report a detailed molecular cytogenetic characterization using Spectral Karyotyping and fluorescent in situ hybridization of parental serum-cultured adherent cells and their sphere-growing stem-like counterpart before and after differentiation from six cell lines established from solid tumors. Our findings indicate increased cytogenetic complexity in sphere-growing stem-like and their differentiated adherent cells compared to parental adherent component suggesting the existence within cell lines of heterogeneous and genetically unstable subpopulations of cells endowed with stem-like features.
