Additionally, flow cytometric analysis of murine tongue squamous cell carcinoma showed that the positive CD74+PDGFRB+ apCAFs was 1.37% in the murine tongue squamous cell carcinoma while we could not find any positive CD74+PDGFRB+ apCAFs in the normal control tissue (Fig. 2G). The gene discussed is PDGFRB; the disease is tongue squamous cell carcinoma.
