Abstract
Rodent models and immortalized or genetically modified cell lines are frequently used—but have limited utility—for studying human prostate development and maturation. Using rodent mesenchyme to establish reciprocal mesenchymal-epithelial cell interactions with human embryonic stem cells (hESCs), we generated human prostate tissue expressing prostate-specific antigen (PSA) within 8–12 weeks. This human prostate model shows species-conserved signalling mechanisms that could extend to integumental, gastrointestinal and genital tissues.
