WebCatecholamine clearance rate was estimated by the changes in catecholamine concentration and alveolar fluid volume over 1 h. Results: The norepinephrine clearance rate was faster than the epinephrine clearance rate in the rat and human lungs. WebResults: Treatment with EPI, robustly enhanced miPSC cardiac differentiation, as indicated by increased expression levels of cardiac-specific markers, GATA4, Nkx2.5 and Tnnt2. Although β-AR signalling is the foremost signalling pathway in cardiomyocytes, EPI-enhanced cardiac differentiation depended more on α-AR signalling than β-AR signalling.
