Prostate Stroma Increases the Viability and Maintains the Branching Phenotype of Human Prostate Organoids

？ Co-culture with human primary prostate stroma improves epithelial organoid viability ？ Stromal cell contact in co-culture directs epithelial organoid branching ？ Prostate stromal cells express morphogenic factors unique from non-prostate fibroblasts ？ Co-culture with stroma maintains AMACR and increases survival of cancer derived-organoid
