Bioelectrical and cytoskeletal patterns correlate with altered axial polarity in the follicular epithelium of the Drosophila mutant gurken

Table 2 In the S10B FE of grk, distinct transversal V_mem- and pH_i-gradients are missing

^§Transversal gradients (fluorescence intensity ratios FE₂/FE₁; larger value vs. smaller value), and ^#a-p gradients (fluorescence intensity ratios pFE/aFE) in the S10B FE of wt and grk were quantified as shown in Fig. 1e (for variability see Additional file: Tables S1 and S2). The higher the fluorescence intensity ratio is, the steeper is the gradient (n = 7; see als Fig. 3b and c). Since, in grk, the cFC and mFC (refering to aFE) are often both more hyperpolarised and more acidic than the aberrant pFC, a-p gradients in grk seem to be somewhat steeper than in wt (cf. Additional file: Fig. S1 and Table S2), but this difference was not significant (cf. Fig. 3c)
