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 PRF1; the disease is cancer.
