Sexually Dimorphic Regeneration of Zebrafish Pectoral Fins

(A) Adult zebrafish, showing locations of fin types.

(B) Comparison of female and male pectoral fin regeneration. Male regenerative defects were clear at 4 days postamputation (dpa) and remained in most animals through 7 and 10 dpa. Arrowheads indicate amputation plane.

(C) Male regenerative failures were present in anterior rays (n = 13, mean � standard error of the mean [SEM]). ^*p < 0.001 by Student′s t test.

(D) Juvenile fish (2 months old) of either sex proficiently regenerated pectoral fins.

(E) Castration rescued regeneration of both pectoral fins in 38% of male animals, assessed at 5 dpa.
