Promotion of Cholangiocarcinoma Growth by Diverse Cancer-associated Fibroblast Subpopulations

ABSTRACT: Here we analyzed mouse and human samples to characterize origin, subtypes, functions and cell-cell interactions of cancer-associated fibroblasts in cholangiocarcinoma, a highly desmoplastic tumor of the liver. Hepatic stellate cell-derived cancer-associated fibroblasts were isolated from two different models of murine intrahepatic cholangiocarcinoma, induced by overexpression of YAP+AKT or KRASG12D in combination with sg-p19, and compared by bulk RNA-sequencing to hepatic stellate cells from two models of liver fibrosis, induced by bile duct ligation or DDC diet. CAF-enriched fractions of from YAP+AKT or KRAS/sg-p19-induced intrahepatic cholangiocarcinoma, were analyzed by single-cell RNA sequencing. A cell suspension from human cholangiocarcinoma, containing all cell populations, was analyzed by single cell RNA-sequencing.
