In breast/pancreatic tumors and normal breast/pancreatic tissues, Cd74high cells expressed fibroblast marker Fsp1/S100a4 (Figure 3F, Figure 4D and Figure 5J) whereas Pdgfra expression appeared to be restricted to tumor tissue only (Figure S2C, Figure 4B and Figure 5G). The gene discussed is PDGFRA; the disease is neoplasm.
