To implement a more accurate classification, EPCAM, MDK, and SOX4; FOLR1, SFTPD, and AGR3; and CD3D, TRAC, and TRBC2 were used as specific markers for tumor cells, epithelial cells, and T cells, respectively, which have been verified and reported in many studies 32-37. The gene discussed is EPCAM; the disease is neoplasm.
