RNAseq of colorectal cancer cell lines (LS1034/HCT116) cultured with iPSC-derived intestinal stroma, separated by EpCAM expression (MACS). Monocultures of each cell line and co-cultures with LS1034 or HCT116 with stroma.

Colorectal cancer (CRC) cell lines (LS1034 and HCT116, representing different genetic backgrounds of CRC) were co-cultured with iPSC-derived intestinal stroma (described in other protocols). Control conditions were each cell line cultured separately. A dose response for HCT116 on stroma was tested using a varying seeding density. After culture, cells were separated using MACS based on EpCAM expression (EpCAM+: CRC cell line / EpCAM-: stroma) and then measured for reciprocal changes in gene expression by RNAseq (i.e. CRC effect on stromal expression and vice verse on cell lines).
