Figure Lengend Snippet: a , Cumulative time spent not responding to the tape (no-response time, seconds). b,c , Averaged time courses ± SEM of tape-directed bouts (b) and AUC (c) of CT (n = 8 M/7 F) and PS (n = 9 M/6 F) offspring. d , Ex vivo DRG neuron stimulation and calcium imaging. Percentage (%) of responsive neurons. e-g , Traces of the calcium-induced changes of fluorescence exclusively in responding neurons after addition of capsaicine (e, n = 35 [CT], 21 [PS]), b-alanine (f, n = 97 [CT], 57 [PS]) and MRS2365 (g, n = 87 [CT], 131 [PS]), and amplitude of the neuronal response measured as AUC of the highlighted duration (for 20 s after the addition of the stimulus), normalized per cell (upper panel) or per experiment (lower panel). Each triangle is a responding neuron, and each dot represents an experiment including 2 mice per group (d-g). h-j , Representative confocal microscopy images of neurofilament H (NFH, h) and GDNF Family Receptor Alpha 2 (Gfrα2, i) in glabrous skin sections and filament length (µm, j) per mm 2 in steady state W8 CT (n = 6) and PS (n = 7) offspring. Scale bars, 30 µm (cropped to 7 µm). k,l , Representative confocal microscopy images of Tubβ3, TH, IB4 and Substance P staining (k) and associated percentages (l) among all Tdt + neurons, in DRG from Nav1.8-Cre + ;Tdt CT (n = 6) and PS (n = 6 [TH + ], 7 [IB4 + , SP + ]) at steady state. Scale bars, 200 µm (cropped to 30 µm). Data are from at least two or three independent experiments. Bars represent mean values, and each dot or square corresponds to a single mouse (a,j,l). Mean + SEM; *P < 0.05, **P < 0.01, ***P < 0.001, ns: not significant; Unpaired t-test (a, c), Mann-Whitney test (d-g, j, l), two-sided.
