Seven types of cells were mainly identified, including cancer cells (CDH1, EPCAM, CDKN2A), endothelial cells (EGGL7, EMCN, PECAM1), endometrial stromal cells (SUSD2), fibroblasts (COL1A2, APOD), lymphocytes (CD28A, CD27, PRF1), macrophages (CD163, FCG2A), and smooth muscle cells (ACTG2) (Fig. 4H‒N). The gene discussed is CD163; the disease is cancer.
