Experimental design of a time-course analysis of regeneration in Nematostella vectensis. a. A schematic depiction of the experimental procedure. Aboral “tail or physa” regeneration appears in the top row and oral “head” regeneration appears in the bottom row. The dissection planes are denoted by dashed red lines and the wound proximal parts were used for RNA extraction and the RNA-Seq screen. b. Photographs of regeneration process corresponding to the time course of the experiment. Left panels show a polyp before and after bisection at a plane marked by the yellow dashed line. The right panel shows pictures of the oral and physal-regenerating parts of the bisected fragments along the time course
