The steady-state membrane potentials of the nurse cells of Drosophila melanogaster incubated in a Ringer's solution containing 2.5 mM K+ averaged 5.2 mV more negative than those of oocytes to which they were attached by intercellular bridges (n = 159; P < 0.001, paired t-test). In sodium azide, the resting potentials of the two cells diminished from a range of -50 to -70 mV to an average of -10 mV, and the transbridge difference disappeared. Therefore, the transbridge difference is dependent… CONTINUE READING
