Fig. 1From: Morphological and molecular characteristics of spheroid formation in HT-29 and Caco-2 colorectal cancer cell linesMorphology of HT-29 and Caco-2 parental adherent monolayer cells and their derived spheroids. Representative phase contrast images from cell lines and their derived spheroids. a Parental HT-29 cells grew as an adherent monolayer, b, c HT-29 derived spheroids cultured at nonadherent and serum free condition showed well-round shape and compact morphology. d Caco-2 parental cells as monolayer and, e, f Caco-2 derived spheroids displayed small and round shape morphologyBack to article page
