EPCAM and keratosis pilaris: Subsequently, we isolated EpCAM+CD45- tumor cells (KP tumor cells) using fluorescence-activated cell sorting (FACS) from the lung of conditional genetic NSCLC KP mice (KP tumor cells) (Figure S11C-D) and transduced them with a plasmid expressing mCherry and luciferase to obtain mCherry and luciferase-expressing KP tumor cells (KP-mCherry-Luc tumor cells) (Figure S13).
