||Fig. 3. RARgamma isoforms display differential distribution at tailbud stages. (A,B), RARgammal expression in head and tail respectively'. Note weak
expression in the branchial arches (A) and the absence of expression in the tailbud (B). (C.D), RARgamma2 expression in head and tail respectively.
Expression can be seen in branchial arches as well as in the tailbud region. The distribution of RARgamma2 in the tail is indistinguishable from that
obtained using the full length RARgamma common probe. Bar, 200 um
