From Crocini et al. 2014 (2) Figure 3: Delay of Ca 2+ release in AP-failing TT of acute detubulated cells.
(A) TPF image of a stained rat ventricular myocyte after formamide-induced osmotic shock; membrane potential optical recording in magenta and [Ca2+]i in green. (Scale bar, 5 μm.)
(B) Average of 10 subsequent fluorescence traces (ΔF/F0) of voltage (magenta) and [Ca2+]i (green) recorded at the three different sites indicated in A: SS and two TTi. APs are elicited at 200 ms (black arrowheads).
(C) Superposition of the Ca2+ traces nearby SS and TT1 (Top) and of SS and TT2 (Middle). (Bottom) A close-up of TT2 and SS superposition (interval indicated by dashed line in the middle trace).
