Fig. 2From: Adult human cardiac stem cell supplementation effectively increases contractile function and maturation in human engineered cardiac tissuesOrganization and microstructure of hECTs. Representative microscopy images of hECTs obtained along the horizontal axis of the hECT. a Single slice image obtained on a two-photon microscope, showing alpha-actinin (red) and collagen fibers (white), scale bar = 100 μm. b Confocal max projection showing Cardiac Troponin T (red), and nuclei stained with anti-histone H2B (green), scale bar = 100 μm. c Confocal max projection showing myofibril organization, with cardiac Troponin T (red), and nuclei stained with DAPI (blue,) scale bar = 5 μmBack to article page
