16 Neutral drift towards crypt monoclonality
17 Neutral competition vs. Asymmetrical Stem Cell Division
18 Lgr5 marks cycling stem cell populations in the small intestine, colon and stomach. Lgr5 intestinal stem cells can generate self-organizing intestinal organoids in-vitro. Paneth cells are niche cells for intestinal stem cells. Lgr5 intestinal stem cells divide symmetrically. Lgr5 stem cells compete for restricted niche space

20 Loss of APC in Non-Stem Cell Populations Fails to Initiate Adenoma Formation
21 Transformation of Stem Cells Rapidly Initiates Intestinal Adenoma Formation Lgr5
22 Restricted Expression of LGR5 Stem Cell Marker in Adenomas Lgr5 Lgr5
23 Lgr5 marks cycling stem cell populations in the small intestine, colon and stomach. Lgr5 intestinal stem cells can generate self-organizing intestinal organoids in-vitro in the absence of a non-epithelial niche. Paneth cells constitute the intestinal niche. Lgr5 intestinal stem cells divide symmetrically. Lgr5 stem cells compete for restricted niche space Lgr5 stem cells are the cell-of-origin of intestinal cancer.

25 Deleting floxed APC in stem cells by Lgr5-CreER. Confetti reporter crossed in (ArnoutSchepers).
26 A single Lgr5 cell in a red adenoma is turned blue: Does it behave like a stem cell?
27 Lgr5 cells in adenomas behave like stem cells
28 Lgr5 marks cycling stem cell populations in the small intestine, colon and stomach. Lgr5 intestinal stem cells can generate self-organizing intestinal organoids in-vitro in the absence of a non-epithelial niche. Paneth cells constitute the intestinal niche. Lgr5 intestinal stem cells divide symmetrically. Lgr5 stem cells compete for restricted niche space Dll1 + early secretory precursors can revert to stem cells upon tissue damage Intestinal label retaining cells are Lgr5+ Lgr5 marks adenoma stem cells

47 Pospective derivation of a Living Organoid Biobank of colorectal cancer patients - The succes rate of organoid derivation > 90% - Organoids closely resemble the original tumor - The spectrum of mutations within the living biobank agrees well with large-scale mutational analysis of CRC - Gene expression analysis indicates that the major CRC subtypes are represented - Tumor organoids are amenable to robotized high-troughput drug screens
