Accumulating evidence indicates that circulating endothelial progenitor cells (EPCs) derived from bone marrow contribute to reendothelialization of injuried vessels as well as neo-vascularization of ischemic lesions in either a direct or an indirect way. Moreover, the number and/or the functional activity of EPCs are inversely correlated with risk factors for cardiovascular disease. Among the different risk factors, cigarette smoking is a major cause of reducing the numbers and function of circulating EPCs. This review is a revision of recent literature on EPC alteration associated with smoking. In particular, we show the recent observation on the effects of active and second hand smoke (SHS) exposure on EPC number and functional activity. This review also considers the effects of nicotine and other smoke compounds on EPC number and activity, in in vitro and in vivo models.

Abstract
Accumulating evidence indicates that circulating endothelial progenitor cells (EPCs) derived from bone marrow contribute to reendothelialization of injuried vessels as well as neo-vascularization of ischemic lesions in either a direct or an indirect way. Moreover, the number and/or the functional activity of EPCs are inversely correlated with risk factors for cardiovascular disease. Among the different risk factors, cigarette smoking is a major cause of reducing the numbers and function of circulating EPCs. This review is a revision of recent literature on EPC alteration associated with smoking. In particular, we show the recent observation on the effects of active and second hand smoke (SHS) exposure on EPC number and functional activity. This review also considers the effects of nicotine and other smoke compounds on EPC number and activity, in in vitro and in vivo models.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
