MMP-1 immunoreactivity of stromal cells of various breast cancer subtypes. Immunohistochemically detected expression of MMP-1 in stromal cells with significant differences in breast cancer subtypes. P-values for overall difference p = 0.0129, luminal A vs. luminal B p = 0.0258, luminal A vs. Her2 p = 0.8334, luminal A vs. triple-negative p = 1.00, luminal B vs. Her2 p = 0.3792, luminal B vs. triple-negative p = 0.0336.
