Correlations between the expression of Kv3.4, Kv4.3, myosin and TH, and the sensitivity to low P_{O 2} of dispersed CB cells

All panels show the time course of changes in [Ca²⁺]_i elicited by the sequential application of 35 mm K⁺ and hypoxia in representative cells exhibiting the immunolabelling pattern depicted in the corresponding pictures. Stimuli application is marked by the horizontal open rectangles. P_O2 was measured in all cases throughout the experiment, but is shown only for data presented in F. Cells were double-labelled with antibodies anti-TH and either anti-Kv4.3 (A, D), anti-Kv3.4 (B, E, F) or anti-myosin.
