Desmin Correlated with Cx43 May Facilitate Intercellular Electrical Coupling during Chronic Heart Failure

Figure 5

Multielectrode array recording of cocultures of primary skeletal myoblasts with cardiac myocytes. Electrograms show the last stimulatory pulse in a series of 10 and the first resulting FAP in cocultures of cardiac myocytes with nontransduced skeletal myoblasts (WT) or desmin-overexpressing skeletal myoblasts (desmin OV). Ten stimulatory current pulses were applied with a frequency of 1 Hz.
