To investigate the expression patterns of 8 genes (RAMP3, GPLD1, FABP5, CD68, CSPG4, SORT1, CSPG5, CSF3R) in various immune cell subpopulations of hepatocellular carcinoma, we utilized the single-cell database TISCH (http://tisch.comp-genomics.org/search-gene/) to analyze GSE140228, which consisted of 62,530 cells. The gene discussed is SORT1; the disease is hepatocellular carcinoma.
