Fig. 2From: Novel developmental bases for the evolution of hypobranchial muscles in vertebratesExpression of Lbx1 and Lbx2 in S. torazame. Expression of Lbx1 (a–d) and Lbx2 (e–g) detected by whole-mount in situ hybridization. Arrowhead and arrows indicate the patch of Lbx1 expression in CMD and paired fin muscle primordia, respectively.
