Supernatant of organoids on the growth, morphology, and gene expression of CAFs. (A and B) Growth of mouse CAFs in the presence or absence of organoid conditioned medium (n = 9). (C and D) Growth of human CAFs in the presence or absence of organoid conditioned medium (n = 9). (E) Expression profile of mouse CAFs markers in the presence or absence of organoid conditioned medium (n = 8). (F) Expression profile of human CAF markers in the presence or absence of organoid conditioned medium (n = 8). (B and D–F) Data are presented as means ± SD. Mann–Whitney U tests. ∗P < .05, ∗∗P < .01, ∗∗∗P < .001. CTR, control; CON, conditioned; FSP1, fibroblast-specific protein 1; hCAF, human cancer associated fibroblast; hOR, human organoid; mCAF, mouse cancer associated fibroblast; mOR, mouse organoid.
