Conclusions: Cell lines derived from tumors are comprised of a mixture of cells, which have different phenotypes. Hence, in cell population-based assays, small sub-population impact or behavior against treatment can be undetected. In this study, S. Kamlund with colleagues has used HoloMonitor M4 in combination with fluorescence microscopy to study JIMT-1 breast cancer cells for an extended time and study Salinomycin effects on individual cells via longitudinal single-cell tracking. Authors have shown that Salinomycin specifically targets a CD24- cell subpopulation by inhibiting its proliferation and the surviving CD24+ cell subpopulation was more epithelial-like.
