Figure 4

Albumin extravasation and tumor endothelial cell matrix alterations. Upper panel shows MSB staining for connective tissue and fibrin with a clear disarrangement of collagen fibres seen in tumours submitted to Hi-based ILP. Lower panel depicts most representative slides of Immunohistochemistry staining with antialbumin where albumin appears in brown, surrounding the vessels in the Hi-treated tumor tissues. More striking effects were clearly observed after Hi+DXR ILP. Original magnification × 16.
