Since decorin has been shown to promote tube formation from endothelial cells and inflammation-induced angiogenesis (Fiedler & Eble, 2009; Nelimarkka et al, 2001; Schonherr et al, 2001; Schonherr et al, 1999; Schonherr et al, 2004), we next asked whether decorin plays a role in angiogenesis in our tumour model. This evidence concerns the gene DCN and neoplasm.
