Figure 4. Spatial location information and signature gene characteristics of functionally heterogeneous cancer cells in ccRCC. (A) Spatial location information of functionally heterogeneous cancer cells revealed by stRNA-seq, illustrating the distribution of cancer cells in tumor lesions. (B) Signature gene characteristics of functionally heterogeneous cancer cells in scRNA-seq data, showing the expression levels of signature genes of different meta programs. (C) Spatial expression patterns for signature gene characteristics of functionally heterogeneous cancer cells in stRNA-seq data. (D) Signature gene characteristics of functionally heterogeneous cancer cells validated by clinical samples of ccRCC using immunofluorescence.
