The LUAD primary cell cultures isolated exhibited a marked positivity for EpCAM and CK7/8 markers, assuring that they were constituted by cancer cells of epithelial origin with the same phenotypic features of the original tumor, as well as negligible expression of CD90 and CD45 markers, thus excluding the presence of fibroblasts and tumor-infiltrating immune cells (Table 1). Here, PTPRC is linked to neoplasm.
