Angiogenesis is the process of generating new capillary blood vessels. It occurs under tight regulation in the female reproductive system, during wound healing and during embryogenesis. Angiogenesis also plays an important role in the pregnancy-associated changes in the reproductive tract. Cigarette smoke inhibits processes that may hinder normal process of angiogenesis resulting in abnormal blood supply to tissues, decreased repair and remodeling. This report summarizes the evidences of the causal association between tobacco smoking and disruption of angiogenesis. Application of small amount of nicotine on day 5 old chorioallantoic membranes (CAMs) did not disrupt the process of angiogenesis, while application of mainstream smokes (MSS) solutions to CAMs caused varying levels of disruption on normal process of angiogenesis and adversely affect capillary plexus formation, diameters of secondary and tertiary vessels. We have also observed that at equivalent doses, sidestream smoke (SSS) can significantly be more potent than MSS and can alter the normal process of angiogenesis more drastically than MSS. It suggests that SSS either contains a toxicant(s) not present in MSS or that the toxicant(s) that produces these effects is present in higher concentration in SSS than in MSS. Therefore, it is undisputed that smoking can interfere the normal process of angiogenesis, which is a vital process to maintain pregnancy and development of fetus. Smoking during pregnancy is harmful to fetal development and is associated with an increased risk of miscarriage, perinatal death and sudden infant death syndrome. Smoking-cessation programs remain a crucial strategy for preventing poor birth outcomes and decreasing the social and financial costs of smoking during pregnancy.
