Lack of Association between Membrane-Type 1 Matrix Metalloproteinase Expression and Clinically Relevant Molecular or Morphologic Tumor Characteristics at the Leading Edge of Invasive Colorectal Carcinoma

Figure 1

(a and b) Absence of MT1-MMP expression at the leading edge of invasive CRC. Note strong MT1-MMP immunostaining of tumor-associated dendritic cells which serves as internal positive control (arrowheads). (c) Weak and (d) strong positivity for MT1-MMP at the leading edge of invasive CRC. Scale bar (a)–(d): 100 μm.
