Distribution of collagen type IV α1–6 chains in human normal colorectum and colorectal cancer demonstrated by immunofluorescence staining using chain‐specific epitope‐defined monoclonal antibodies

Background and Aim: Loss of basement membrane (BM) components, such as type IV collagen, has been demonstrated in colorectal cancer, but the fine diversity of the assembly of α (IV) chains, the composition of type IV collagen, and alterations in the collagen have not been fully analyzed. Here, we defined immunohistochemically the expression of α1–6 (IV) chains in colorectal cancer tissues and adjacent normal mucosa by the use of chain‐specific monoclonal antibodies.
