1. Using the whole-cell recording mode of the patch-clamp technique, we investigated the calcium currents in isolated cells from rat portal vein in short-term primary culture. 2. From a holding potential of -70 mV the cells presented two types of calcium currents with 5 mM-extracellular calcium: one type was activated by small depolarizations and inactivated quickly (fast calcium current), whereas the other required stronger depolarizations for activation and inactivated more slowly (slow… CONTINUE READING
