Characteristics of the reparative regeneration of fins in the polypterid fish (Polypteridae, Actinopterygii)

Abstract: Epimorphic regeneration of fins was studied in different ray finned fishes (Actinopterygii), but species representing the phylogenetically basal lineages of the taxon have remained outside the attention of researchers. Information on the regenerative abilities of these groups is important both for understanding the evolutionary origins of the epimorphic regeneration phenomenon and for assessing the universality of regen erative potencies in Actinopterygii. Addressing this problem, we studied for the first time… Show more

“…Heteromorphic regeneration has been previously reported for salamanders (42), lungfish (6), and dermal fin ray regeneration in teleosts (43). Repeated fin amputations also result in abnormal endoskeleton morphologies in Polypterus (15). In our study, all 5 regeneration-competent species examined showed varying degrees of heteromorphic regeneration.…”

“…However, evidence of tail regeneration after endoskeleton amputation has been shown in zebrafish (13). Thus far, only 2 actinopterygian species, both from the earliest branching ray-finned fishes, the Polypteridae, have been found to fully regenerate paired fins, including the endoskeleton: the Senegal bichir Polypterus senegalus (14,15) and the ropefish Erpetoichthys calabaricus (15). Currently, our understanding of the evolution of appendage regeneration is hindered by limited knowledge of the regeneration capabilities across fish clades.…”

“…In contrast to the numerous well-documented exoskeletal regeneration studies, there are only a few studies on endoskeletal regeneration within the Actinopterygian clade. Complete endoskeletal regeneration has been reported in the case of two Polypterid species, the bichir (Polypterus senegalus) [34,42,43] and the ropefish (Erpetoichthys calabaricus) [43]. In a recent study, Schneider and coworkers provided evidence that endoskeletal regeneration can be also observed in two other basal Actionpterygians, the paddlefish (Polyodon spathula) and the spotted gar (Lepisosteus oculatus) [44].…”

“…However, their regenerative abilities are thought to be limited to the dermal fin ray skeleton 11,12 . Thus far, only two actinopterygian species, both from the Polypteridae family, have been found to fully regenerate paired fins including the endoskeleton: the Senegal bichir Polypterus senegalus 13,14 and the ropefish Erpetoichthys calabaricus 14 . Currently, our understanding of the evolution of appendage regeneration is hindered by limited knowledge of the regeneration capabilities across fish species.…”
