Establishment of a living biobank of CMT organoids. (a) Sampling and generation of organoids from different primary canine epithelial mammary tissues from the same dog: malignant (carcinomas), benign (adenomas), or non-neoplastic mammary tissues. (b) Success rates for establishing 3D in vitro organoids from the indicated mammary tumors and normal mammary epithelium. Values indicate the number of donor tumors from which models were successfully derived versus the total number of donor tumors for a total of 16 dogs. (c) Brightfield images of 3D organoids of mammary tumor (ORG-63-C) and of normal mammary epithelium (ORG-63-N) grown in Basement Membrane Extract 1 day, 7 days (passage 3), and 180 days (passage 13) following isolation. Both organoid lines are derived from dog 63. Scale bar, 50 μm.
