Slides of the individual TMA reflecting the tumor center (TMA TC, n = 73), the invasion front (TMA IF, n = 69), and corresponding lymph node metastases (TMA LM, n = 22) and adjacent normal tissue (TMA NO, n = 24) were stained for CD147 expression using IHC, and IRSs were determined (Figure 3A). This evidence concerns the gene BSG and neoplasm.
