Human Lung Organoids Grown in Cultrex UltiMatrix RGF Basement Membrane Extract. Adult stem cells isolated from human lung biopsy tissue were embedded in Cultrex UltiMatrix RGF Basement Membrane Extract (R&D Systems, Catalog # BME001-05) and cultured in media for 20-60 days. Lung organoids were able to differentiate and exhibit markers for various cell types of the lung. A) Lung organoids were stained with anti-Cytokeratin 5 (KRT5) (green; Novus Biologicals, Catalog # NB110-56916) and with anti-p63/TP73L (red; R&D Systems, Catalog # AF1916) to visualize basal cells. B) Lung organoids were stained with anti-Podoplanin (PDPN) (green; Novus Biologicals, Catalog # NB600-1015) to visualize alveolar type I cells. C, D) Lung organoids were stained with anti-Muc5ac (green; Novus Biologicals, Catalog # NBP2-15196) to visualize Goblet cells and with anti-Sox2 (red; R&D Systems, Catalog # MAB2018). All samples were counterstained with the nuclear stain DAPI (blue; Tocris, catalog # 5748).

Human Descending Colon Organoids. Adult stem cells isolated from human descending colon were embedded in Cultrex UltiMatrix RGF Basement Membrane Extract (R&D Systems, Catalog # BME001-05) and cultured in growth medium for 30 days prior to imaging. A, B) Descending colon organoids were stained with Chromogranin A (green; R&D Systems, Catalog # MAB90981) to visualize intestinal enteroendocrine cells, and counterstained for E-Cadherin (red; R&D Systems, Catalog # AF748) and DAPI (blue; R&D Systems, Catalog # 5748).
