Epidermal growth factor receptor (EGFR) overexpression has been associated frequently with squamous cell carcinomas (SCC) and SCC cell lines. In most cases the level of EGFR on the tumours from which the cell lines were derived has not been determined, nor have EGFR levels been determined for xenograft tumours from the cell lines. In this study we(More)
Cell to cell variation of epidermal growth factor (EGF) receptor mRNA levels in heterogeneous tissues has been demonstrated with an in situ assay that couples reverse transcriptase with the polymerase chain reaction (in situ RT-PCR). EGF receptor mRNA is consistently more highly expressed in regions where cell division occurs; EGF receptor mRNA is markedly(More)
Monoclonal antibodies which bind to breast cancer have been used to evaluate the detection of metastatic disease in axillary lymph nodes. Three monoclonal antibodies (H59, H71, and H72) were reacted with tissue sections of primary tumors and axillary nodes from 24 mastectomy specimens and four specimens from glandular mastectomies for benign disease.
