BACKGROUND A large fraction of murine tumors induced by transgenic expression of SV40 large T antigen (SV40 TAg) exhibits a neuroendocrine phenotype. It is unclear whether SV40 TAg induces the neuroendocrine phenotype by preferential transformation of progenitor cells committed to the neuroendocrine lineage or by transcriptional activation of neuroendocrine(More)
In intestinal and pyloric epithelia, leucine-rich repeat-containing G protein-coupled receptor 5 (Lgr5)-expressing cells represent long-lived adult stem cells that give rise to all epithelial cell types, including endocrine cells. Ablation of the Apc gene in Lgr5-expressing cells leads to intestinal and pyloric adenomas. To assess whether all epithelial(More)
