Abstract
Zebrafish (Danio rerio) is an ideal model organism for exploring the ability and mechanism of tissue regeneration in the vertebrate. However, the specific cellular and molecular mechanism of caudal fin regeneration in zebrafish remains largely unclear. Therefore, we first confirmed the crucial period of fin regeneration in adult zebrafish by morphological and histological analysis. Then we performed RNA-Seq analysis of the caudal fin regeneration at three key stages, which provided some clues for exploring the mechanism of caudal fin regeneration. Moreover, we also determined the expressions of inflammatory cytokines IL-1β, IL-6, IL-8, IL-10, TGF-β, and the immune-related pathway JAK2α and STAT1b in the caudal fin of zebrafish following fin amputation by quantitative real time PCR (qPCR). Particularly, Hsp90α expression at mRNA and protein level determined by qPCR and Western blotting, respectively, and whole-mount in situ hybridization of Hsp90α were also performed in this study. The results showed that inflammatory cytokines were mainly expressed in the early period of caudal fin regeneration (1-3 days post amputation, dpa), indicating that fish immune system was involved in the fin regeneration. Furthermore, the high expression of Hsp90α in the vicinity of blastema and blood vessels of the regenerating fin suggests that Hsp90α may play a role in the initiation and promotion of caudal fin regeneration. Overall, our results provide a framework for further understanding the cellular and molecular mechanism in caudal fin regeneration.
