Figure Lengend Snippet: a) Brightfield images of colon tumor organoids in hydrogel droplets on day 3, 6, 8 and 12 (scale bar 250 µm). b) Size development analysis of colon tumor organoids over several days, with average size highlighted above (n organoids < 110). c) Brightfield images (scale bar 250 µm) and H&E staining (scale bar 100 µm) of organoids grown in domes (1:6 dilution) or droplets. d) mIF staining of organoids in hydrogel droplets and domes (1:6 dilution) on day 12 (ECAD white, Ki67 red, SOX9 turquoise, CEACAM5 pink, scale bars 100 µm). e) Drug treatment of bioreactor grown tumor organoids. Dose-response curves to compounds FOLFOX (5-Fluorouracil,: Leucovorin:Oxaliplatin = 25:5:1, the concentration specified in the graph is based on 5-Fluorouracil), SN-38, Bortezomib, Capecitabine, quantified by fluorescence analysis of cell viability by live/dead staining (n samples = 3). Schematic was created with BioRender.com.
Article Snippet: The highest drug concentrations were chosen as follows: 1 μM Bortezomib (Tocris), 200 μM SN-38 (Tocris), 50 μM Capecitabine (Selleckchem) and the combinatorial FOLFOX with 50 μM 5-Fluorouracil (Tocris), 2 μM Oxaliplatin (Tocris), 10 μM Leucovorin (Selleckchem).
