Characterization of Multiple Ion Channels in Cultured Human Cardiac Fibroblasts (original) (raw)
Figure 1
Families of membrane currents in human cardiac fibroblasts.
A. Noisy current was activated at positive potential. Currents were elicited with the protocol shown in the inset (0.2 Hz). B. A transient outward current was activated in a human cardiac fibroblast by the same protocol as in A. C. A current with inward rectification activated by hyperpolarized potentials (inset) was co-present with the noisy current. D. Voltage-dependent current with outward rectification was recorded with the same protocol as in C. E. An inward current with fast inactivation activated by depolarization voltage steps (inset) was co-present with the noisy current. F. An inward current with slow inactivation (arrow) activated by the same protocol as in E was co-present with the noisy current.
