Isolation and identification of rat myocardial cells. A – The morphology of the extracted myocardial cells was observed under a microscope on days 1, 2, and 3. Magnification, 100×, scale bars, 50 µm. B – Localization and expression of cTnT was evaluated with immunofluorescence assay in the extracted myocardial cells. cTnT is stained green and nuclei are stained blue (DAPI). Magnification, 400×, scale bars, 10 µm (down)
