RNA-seq of LGR5(+) and LGR5(-) cells isolated from human colon adenoma organoids

Human colon adenoma organoids (n=3 patients) were dissociated into single cells. Cells were incubated with a magnetic bead bound to an LGR5 antibody and run through a magnetic column. Magnet bound cells and flow through negative (FTN) cells were obtained. Magnet bound and FTN cells were incubated with an APC-check reagent (which binds to the magnetic bead on the LGR5 antibody) and DAPI, before being sorted by flow cytometry. 3 populations of live (DAPI-) cells were collected: FTN: Flow through negative. LGR5 negative by magnet and by flow cytometry SortedNeg: Magnet bound cells that were negative for LGR5 by flow cytometry SortedPos: Magnet bound cells that were positive for LGR5 by flow cytometry
