LDHA and pancreatic intraductal papillary-mucinous neoplasm: Figure 6 demonstrates a significantly higher percentage of Aldh+ cells in PanIN than in IPMN (~40% vs. 10%; Figure 6Aa–d) at a cell density of 5 × 105 cells/ml and incubation time of 45 min. Similar results were obtained with a cell density of 2 × 105 cells/ml (Figure 6Be–h).
