Assessment of markers of lineage-specific differentiation in PTENWT and PTENLox/Lox/villinCre mice. A: alkaline phosphatase staining (absorptive cell lineage). B: alcian blue staining (goblet cell lineage, back arrowheads). C: hematoxylin and eosin (H&E) staining showing Paneth cells with the characteristic eosinophilic granules at the crypt base (white arrows) in duodenum (top) and jejunum (bottom). D: lysozyme staining (Paneth cell lineage). E: chromogranin A staining (enteroendocrine cell lineage).
