Objective: Target of this study was to test the capacity of chondroitin sulfate (CS) and glucosamine sulfate (GS) to induce in vivo angiogenesis. Methods: The proangiogenic activity of these compounds was analyzed through the assays in chorioallantoic membrane (CAM) of chick embryo and dorsal skin vascularization in mice, but before was realized a cell viability assay with human umbilical veins endothelial cells (HUVEC). Results: In the viability assay, concentrations tested between 30 and 3000 μg/ml showed a reduction of viable HUVEC number. In the CAM assay, CS and GS in an amount 2.0 mg/implant increased the vessels number as compared to control (phosphate buffered saline-PBS). In the assay of the dorsal skin vascularization of adult Swiss mice, the groups treated with CS (2 mg/implant; Gelfoam plug) exhibited an increase in the vessels number into plugs (0.52 ± 0.08 g/dl..
