Abstract

The endothelial progenitor cells (EPC) were first described by Asahara in 1997. These cells were able to migrate to the site of endothelial lesion and differentiate into mature endothelial cells promoting new vessel formation and helping in endothelium recovery. Thrombosis, oxidative stress and inflammatory process can be initiated by an arterial lesion and affect proliferation of local endothelial and smooth muscle cells, also influencing EPC migration to the site of injury. Dermatan sulfate (DS) and fucosylated chondroitin sulfate (FuCS) are glycosaminoglycan (GAGs) with well known antithrombotic and anticoagulant activities, their anti-inflammatory function was recently described. This project proposes to analyze DS and FuCS activity in the inflammatory process and EPC, used as cellular therapy, migration, proliferation and differentiation, after an arterial lesion. To analyze GAGs influence in inflammation, EPC migration and neointima development we will study the expression of P-selectin, ICAM-1, SDF-1, VEGF, eNOS, NF-k² and TGF-². The expression of these proteins is directly correlated with cell migration proliferation and inflammatory reaction. The determination of these factors can help understanding the mechanisms involved in endothelium recovery after lesions and also developing new therapies for cardiovascular disease treatments, using the EPC together with anti-inflammatory and anticoagulant drugs.
