Figure 1. Images of growing CRCs and CRCs seeded into pseudo-ALI culture.

Left, image of nasopharyngeal CRCs grown on a collagen-coated tissue culture plate co-cultured with irradiated 3T3-J2 feeder fibroblasts (captured with a phase-contrast microscope). Right, images of pseudo-ALI cultures with CRCs seeded into the apical side of a 24 well plate-sized transwell.
