Fig. 4 The role of edar in expression of developmental patterning genes during early scale development.
Expression of edar (A, B) and eda (C, D) in early forming scales; arrowheads indicate site of expression of initial forming scales. A) edar expression above site of scale formation in 8 mm long (approximately 30 dpf juvenile fish) and in larger juveniles (9 mm; 30 dpf). C) eda expression during early scale development on the flank (8 mm) and in forming scales of older juvenile fish (10 mm, D). Expression of developmental genes bmp2b and shh in early scale development in wildtype (E, G) and flste370f (F, H) juveniles (9 mm).
