ERBB2 and neoplasm: The neu-positive viable dormant tumor cells contained a predominant Ki67− quiescent fraction in the lungs (Fig. 3b, Ctrl and FAC) or in the liver (Fig. 3f, all groups), except for the FAC/AIT group showing equal proportions of Ki67− quiescent and Ki67+ indolent fractions only in the lungs (Fig. 3b).
