The cause of the long-term cardiac vulnerability, in subjects born of low birth weight, are not well understood. Using well-established rodent models of maternal protein restriction (which mimics maternal malnutrition during pregnancy) and bilateral uterine vessel ligation (which leads to uteroplacental insufficiency) we have stereologically examined the effect of intrauterine growth restriction on the number of cardiomyocytes formed within the heart of the offspring. Our findings demonstrate that intrauterine growth restriction can adversely impact on the complement of cardiomyocytes in the heart in early life. Since the proliferative capacity of cardiomyocytes is markedly attenuated postnatally, our findings provide a plausible explanation as to how intrauterine growth restriction leads to long-term vulnerability to cardiac disease. Keywords: intrauterine growth restriction, cardiomyocytes, stereology, developmental origins of disease. Introduction Convincing evidence from epidemiological and experimental studies demonstrate that growth in utero can program for long-term health and disease; with low birth weight associated with adverse long-term effects in the adult heart [1-3]. The cause of the long-term programming of cardiac disease in individuals who were born of low birth weight is the subject of intense research world-wide. Development of the heart The heart is the first organ to form in the embryo and this is a consequence of the increased oxygen and nutrient demands of growing tissues as the embryo develops. The human heart commences development in week 3 of gestation and is in a relatively mature form by 10 weeks of gestation [11, 12]. The formation of the multi- chambered heart is a complex process that involves formation of the linear heart tube, heart looping, formation of the cardiac chambers, and septation [13]. It involves an interplay of cellular proliferation and programmed cell death; processes that are tightly regulated by extracellular and intracellular factors [14]. The primitive heart tube is formed by 3 weeks in gestation and the heart undergoes rhythmic contractions by the end of the fourth of week of gestation. Early in gestation the developing heart undergoes a process of looping whereby the primitive chambers are brought into the spatial alignment of the mature heart. The heart then undergoes septal formation to initially divide the atria from the ventricles and then further division of the atria and ventricles. During this time there is also a spiralling division of the outflow tract of the heart to bring the aorta in alignment with the left ventricle and the pulmonary trunk in alignment with the right Medimond. All these processes take place by 10 weeks of gestation with the fetal heart in a relatively mature form by this gestational time point. In the last trimester of human pregnancy the cardiomyocytes undergo a process of maturation, whereby the cardiomyocytes exit the cell cycle and becoming terminally differentiated [15], in preparation for the hemodynamic transition at birth, when there is a marked increase both in heart rate and blood pressure. During this process, there is cytoplasmic myofibril assembly into sarcomeres and enhanced contractile activity within the cardiomyocytes [16]. Cell division is a rare event when cardiomyocytes have become differentiated [15]. In the human heart, most cardiomyocytes have become differentiated by birth or soon after birth; growth of the myocardium after this time is predominantly due to cardiomyocyte hypertrophy and extracellular matrix deposition [16]. Proliferation of cardiomyocytes is not precluded in the postnatal heart, although it is a relatively rare event with postnatal regenerative capacity markedly reduced [17, 18]. In the case of rodents the cardiomyocytes are still proliferating at the time of birth and they generally undergo the process of maturation in the first two weeks postnatally; in the first week of life they continue to proliferate and in the second week of life they undergo a process of maturation whereby they become binucleated [19, 20]. Hence, in the rodent heart, mature cardiomyocytes are easily identified as they are binucleated; this is not the case in the human heart where the majority of the cardiomyocytes remain mononucleated. Intrauterine growth restriction th Intrauterine growth restriction is defined as growth below the 10 percentile for gestational age. During pregnancy, the placenta is the key interface between the maternal and fetal circulation, with placental function directly influencing fetal growth. Placental insufficiency is largely due to an inadequate vascular adaptation at the uteroplacental interface, which leads to restricted delivery of oxygen and nutrients to the fetus and ultimately growth restriction as a result of hypoxia and hypoglycaemia. In general, placental insufficiency develops late in pregnancy, during the third trimester. Within our laboratories we have well-established models of early life growth restriction in rats, whereby growth restriction of the fetus is induced as a result of maternal protein restriction [10, 21-23] or bilateral uterine vessel ligation [9, 24-26]. The model of maternal protein restriction mimics malnutrition in pregnancy (where there is reduced protein and elevated starch content in the maternal diet) throughout pregnancy, whereas the bilateral uterine vessel ligation model is a model of late gestational placental insufficiency. The diets are semi-purified diets where all components of the low protein diet and the control diet are the same except for the casein and starch content; the starch content is elevated in the low protein diet and as a result the low protein diet and normal protein diets are close to isocaloric. The offspring exposed to maternal protein restriction exhibit symmetric growth restriction with an approximate 12 to 18% reduction in birth weight compared with control offspring exposed to a maternal normal protein diet. Bilateral uterine vessel ligation leads to asymmetric growth restriction of the offspring, with approximately 10 to 15% reduction in fetal body weight and litter size compared with controls. In the maternal protein restriction model we have stereologically counted the number of cardiomyocytes in the hearts of offspring at birth and at 4 weeks of age (in the left ventricle which is the dominant ventricle postnatally). In our placental insufficiency model we have counted the number of cardiomyocytes in the hearts at 7 days of age. Hence, as cardiomyocytes continue to proliferate in the rat heart in the first week of life, it appeared that there was catch-up hyperplasia of the cardiomyocytes in the early postnatal period.
