PTPRC and neoplasm: Tumours from gp130F/F stomachs were dissected, disaggregated and sorted by flow cytometry into three populations: gastric epithelial cells (E-cadherin+/CD45−), macrophage (Mφ) enriched immune cells (CD45+/CD11b+/SSClow/CX3CR1+/CD64+/MHCII+) and Mφ depleted immune cells (CD45+/Mφ depleted) (Figure 4D).
