Figure 1 (IMAGE) Shinshu University Caption The researchers observed several electric parameters such as the beating rate. The nodal-like cells beat a little faster than the working-type cells. The dV/dt acts like the starting software. The APD is the breadth. The SHOX2+ Cells are the nodal-like cell markers. Troponin T (cTNT) is the marker for such cardiomyocytes. Their abundance is one (nodal-like) to nine (working-type). The MLC2V is the mature working-type cell. MLC2A can be found in nodal-like and immature working-type cells. MLC2A is found mostly in vitro, immature working-type and nodal-like cells.
