Abstract
Zebrafish have high regenerative ability in several organs including the fin. Although various mechanisms underlying fin regeneration have been revealed, some mechanisms remain to be elucidated. Recently, extracellular vesicles (EVs) have been the focus of research with regard to their role in cell-to-cell communication. It has been suggested that cells in regenerating tissues communicate using EVs. In this study, we examined the involvement of EVs in the caudal fin regeneration of zebrafish using an in vivo electroporation method. The process of regeneration appeared normal after in vivo electroporation, and the transferred plasmid showed mosaic expression in the blastema. We took advantage of this mosaic expression to observe the distribution of exosomal markers in the blastema. We transferred exosomal markers by in vivo electroporation and identified EVs in the regenerating caudal fin. The results suggest that blastemal cells communicate with other cells via EVs during caudal fin regeneration.
