Fig. 1. Amputated zebrafish caudal fins display position-dependent rates of
regenerative growth. (A) Appearance of the zebrafish fin immediately following
a double amputation surgery, with the injured portion at the top of the image.
The amputation planes are indicated by arrows (black, proximal; red, distal),
and asterisks mark lateral rays 2 and 3 that are compared in this study. (B)
Only 4 days after amputation (dpa; assessed at 33°C), the fin has
regenerated a significant number of lost structures. The ventral lobe of the
fin (left), after a more proximal amputation, is regenerating more rapidly
than the right, dorsal lobe. (C) By 7 dpa, the ventral regenerate has reached
nearly the same PD level as the dorsal regenerate. (D) Growth is greater after
proximal amputations compared with distal amputations throughout regeneration
(mean±s.e.m.; *P<0.05, t-test). (E)
Growth rate is greater after proximal amputations than distal throughout
regeneration.
