Figure 2B showed that these cells were uniformly distributed in the ccRCC samples and that the gene expression levels were positively associated with the amount of gene expression (0.88). This indicated that the screened cells are suitable for further analysis. Figure 2C showed the ten most variable genes in selected cells, including JCHAIN, RGS5, ENPP2 and MZB1. The gene discussed is RGS5; the disease is nonpapillary renal cell carcinoma.
