Dorsal-anterior (DA, upper panel), dorsal-posterior (DP, upper panel), ventral-anterior (VA, upper panel), ventral-posterior (VP, upper panel), lateral-anterior (LA, lower panel) and lateral-posterior (LP, lower panel) hypodermis are surrounded by dashed line and have been identified using
lin-26p::
vab-10(ABD)::MCHERRY hypodermal markers. B) Distributions ofthe dorsal-posterior/dorsal-anterior (DP/DA), lateral-posterior/lateral-anterior (LP/LA), ventral-posterior/ventral-anterior (VP/VA), dorsal-posterior/ventral (DP/V); dorsal-anterior/ventral (DA/V), dorsal-anterior/lateral (DA/L) rates of fluorescence intensity measured in
