TNC and neoplasm: Therefore, β4 expression was significantly associated with laminin-5 expression within tumors (p < 0.001) (Table 1 and Figure 3B), but not in the invasive front portions of tumors, while β6 expression was significantly associated with tenascin-C expression in the tumor cells, or both tumor cells and the stroma (p = 0.016) (Table 1 and Figure 3A), but not in the stroma within tumor tissues alone.
