Fig. 7From: Membrane potential modulation of ionomycin-stimulated Ca2+ entry via Ca2+/H+ exchange and SOC in rat submandibular acinar cellsMembrane potential changes induced by 4 μM TG and 5 μM IM. Membrane potentials before stimulation (a), 12 min after the addition of TG or IM at 4.5 mM [K+]o (b) and at 151 mM [K+]o (c) were shown in this figure. IM (5 μM) significantly depolarized the membrane potential. Asterisks indicate significantly different (p < 0.05)Back to article page
