Expression of Osteonectin correlates with levels of fin regeneration in zebrafish (danio rerio). FEBS 2007. 7-12 July, Vienna, ÁustriaAUT: LCA00739;http://hdl.handle.net/10400.1/4502Mammals have the ability to regenerate some tissues such as blood and liver, but the majority of organs fail to regenerate. In contrast, zebrafish is capable of regenerating complex organs/tissues such as optic nerve, scales, heart and fins, and is presently one of the most used metazoan in regeneration research. Zebrafish fin is composed of multiple fin rays with bony parts (lepidotrichia) originated by intramembraneous ossification. Fin regeneration is an epimorphic process dependent on formation of a specialized structure (blastema), consisting of mesenchymal-like cells located between stump tissues and the wounded epidermis,engconference object2014-05-30
