Single cell flow cytometry of ccRCC tissue suspensions confirmed on protein level that the majority of CD14+CD209+ cells co-expressed CD64A (M1-marker) with MerTK and MSR1/CD204 (both M2-markers) (Figure 2C) indicating that ercDCs are mosaic cells on the single cell level. Here, MERTK is linked to nonpapillary renal cell carcinoma.
