Zebrafish keratin 8 is expressed at high levels in the epidermis of regenerating caudal fin.
Cytokeratins are structural proteins of the intermediate filament family and are mainly expressed in epithelial cells. In several vertebrates it has been shown that keratin 8 is expressed in simple epithelial tissues, some non-epithelial tissue and in hyper-proliferative tissues during development and tumor transformation. We previously cloned and characterised the zebrafish (Danio rerio) homol...
متن کاملThe Primary cell culture from caudal fin tissue of Caspian Kutum (Rutilus frisii kutum)
In the present study, the primary cell lines were derived from caudal fin explants of the Caspian Kutum (Rutilus frisii kutum), using two treatments (tissue culturing without enzyme and after trypsin treatment). For this purpose, pieces of caudal fin tissue (1 millimeter cubic) were isolated from 10 healthy young fish with an average weight of 12±1 g and a mean length of 11±1cm in sterile condi...
متن کاملFate restriction in the growing and regenerating zebrafish fin.
We use transposon-based clonal analysis to identify the lineage classes that make the adult zebrafish caudal fin. We identify nine distinct lineage classes, including epidermis, melanocyte/xanthophore, iridophore, intraray glia, lateral line, osteoblast, dermal fibroblast, vascular endothelium, and resident blood. These lineage classes argue for distinct progenitors, or organ founding stem cell...
متن کاملHydrodynamics of a Flexible Soft-Rayed Caudal Fin
The paper addresses hydrodynamic performance of a slender swimmer furnished with a flexible small-aspect-ratio soft-rayed caudal fin. The recoil of the fin is found by solving the coupled hydro-elastic problem, in which the structure of the fin is modeled by a cantilever of variable cross section and the hydrodynamic forces acting on it are modeled using the elongated body theory. It is shown t...
متن کاملNumerical Study on Hydrodynamic Performance of Bionic Caudal Fin
In this work, numerical simulations are conducted to reveal the hydrodynamic mechanism of caudal fin propulsion. In the modeling of a bionic caudal fin, a universal kinematics model with three degrees of freedom is adopted and the flexible deformation in the spanwise direction is considered. Navier-Stokes equations are used to solve the unsteady fluid flow and dynamic mesh method is applied to ...
