Abstract

The most spectacular regenerative events in vertebrates are epimorphic regeneration. In this study, interestingly, a whole-body extract 24 h after tail amputation enhanced primary cell growth and viability compared to that of a non-tail amputated body. Additionally, these effects of extract treatment in vitro were dose-dependent occurring at concentrations of 0.02, 0.05 and 0.1 mg/ml. This is the first in vitro study on the interaction between primary fin cells from glass catfish and tail amputated body extracts of zebrafish. These results provide an essential knowledge base for rational approaches to tissue and organ regeneration.

Key words: Cell growth, cell viability, extract, glass catfish, regeneration, zebrafish.
