Figure 5.

Some but not all of the programs of tail resorption are inhibited. (A) Image of a control tadpole tail at stage 64 showing that the fins are already resorbed and that the muscle is dying as the tail starts to resorb quickly. (B) An oPRL transgenic tail at the end of metamorphosis. The fins have grown but most of the muscle has resorbed. (C) An oPRL transgenic tail 3 months after metamorphosis. Note the growth of the retained tail. All sections are cross sections stained with hematoxylin-eosin. The scale bars equal 1 mm.
