Multi-stromal organoid co-culture modelling reveals epithelial-fibroblast heterogeneity in pancreatic cancer and pancreatitis.

Distinct epithelial and fibroblast features in pancreatitis and PDAC are revealed through multi-stromal organoid co-cultures, highlighting disease-specific heterogeneity.

• Why it matters: Understanding fibroblast diversity and epithelial-stromal interactions is crucial because these cell types influence disease progression and treatment response in pancreatic diseases, yet their differences in inflammation versus cancer are poorly understood.
• What they did: The study compared fibroblast populations and cell interactions in human samples, mouse models, and organoid co-cultures, incorporating pancreatic stellate cells, fibroblasts, and mesothelial cells to model disease states.
• The result: Findings demonstrate unique cellular features in pancreatitis and PDAC, providing new models to identify disease-specific markers and potential therapeutic targets, advancing personalized treatment strategies.
