Spatial Analysis of Intraductal Papillary Mucinous Neoplasms Defines a Paradoxical Keratin 17-positive, Low-grade Epithelial Population Harboring Malignant Features

Our study demonstrates that Keratin 17 marks a distinct transcriptional signature in a subpopulation of epithelial cells within histologically low-grade IPMN. This population of cells likely represents a transitional state of histologically low-grade epithelial cells undergoing progression to a higher grade of dysplasia and thus may represent a higher risk of progression to carcinoma.
