Fig. 1From: An organoid model of colorectal circulating tumor cells with stem cell features, hybrid EMT state and distinctive therapy response profileEstablishment of organoid cultures generated from CRC patients (PDOs), subcutaneous xenografts (XDOs) or CTCs (CTCDOs). PDOs were directly generated from a colon adenocarcinoma surgically removed from a CRC patient. To obtain CTCDOs, PDOs were expanded, transduced with a luciferase-(LUC) encoding vector and orthotopically injected in the colon of immunocompromised mice. CTCs were then isolated from mouse peripheral blood collected by cardiac puncture and used to produce CTCDOs. XDOs were generated from subcutaneous xenografts and used a control for comparative in vitro and in vivo analysesBack to article page
