Analysis of epidermal thickness and ultrastructure (A) Graph depicting the epidermis thickness evaluated in the body region close to the injection site. (B) Graph depicting epidermis thickness evaluated in the body region far from injection site. Each bar is the mean ± s.d. of five independent samples in which epidermis thickness was evaluated in 5 different sections. In each section 6 measurement were taken. Values were normalized versus the corresponding control, to which an arbitrary value of 100% was attributed. **p < 0,001. (C) Dorsal epidermis of a water injected control from a body region close to the injection site. (D) Dorsal epidermis of a RNAi animal from a body region close to the injection site (E) Ventral epidermis of a water injected control from a body region close to the injection site. (F) Ventral epidermis of a RNAi animal from a body region close to the injection site. Scale bars correspond to 2 µm. Ultrastructural observations were performed in three independent experiments in which we analyzed several ultrathin sections of two animals per experimental class.
