The most notable difference is the physical mechanism the cells use to exit. During angiopellosis, the endothelial cells are the most active in the process, while in diapedesis it is the white blood cell that are the most physically active during the process. During angiopellosis the extravasating cell remains round in morphology and only slightly changes shape as a result of the vasculature remodeling around it. However, during diapedesis the white blood cells significantly change shape as they migrate through the blood vessel.

While Perlecan suppression causes substantial inhibition of tumor growth and neovascularization in null mice, in contrast, when perlecan-null cells are injected into nude mice enhanced tumor growth is observed when compared to controls. Cancer progression and pathogenesis is intimately linked to extracellular matrix composition and the role of perlecan and other ECM molecules in cancer is being studied by a large number of laboratories. Since the basement membrane is the first obstacle in the way of extravasating carcinoma cells, the functions of perlecan in this process are multiple. One model system used to study perlecan expression in carcinoma cell lines is that of the MeWo/70W melanoma metastatic progression cell lines.

On the contrary, the initial lesion shows increased capillary permeability with "very large numbers" of neutrophils migrating from the dilated gingival plexus into the junctional epithlieum and underlying connective tissue (yet remaining within the confines of the region of the sulcus) and macrophages and lymphocytes may also appear. Loss of perivascular collagen occurs; it is thought that this is due to the degradative enzymes released by extravasating leukocytes, such that the collagen and other connective tissue fibers surrounding blood vessels in the area dissolve. When this occurs the gums will appear bright red and either bulbous or rounded, from all the excess fluid building up in the infected area. The initial lesion appears within two to four days of gingival tissue being subjected to plaque accumulation.
