11 fold) and COX2 (1. 3 Figure below shows the pressure changes in the left atrium, left ventricle and aorta throughout two cardiac cycles. Manipulating the activity of pathways that are active during cardiac development, such as the ErbB signaling pathway and the Hippo pathway, are currently among the most promising that may be harnessed for this purpose. In contrast, the small remaining population of diploid, mononucleated cardiomyocytes still has the capacity to proliferate. Oxygenated blood from the lungs is transferred to the left atrium and then to the left ventricle. The non-chamber regions, the atrioventricular canal, outflow tract, and sinus venosus, however, express TBX2, TBX3, MSX2, and/or ID2, all of which function to suppress proliferation and chamber differentiation.
