Club cells active role in epidermal regeneration after skin hyperplasia of koi carp Cyprinus carpi

Abstract
Carp pox is a flat epidermal hyperplasia affecting common carp (Cyprinus carpio Linnaeus, 1758) and its ornamental form koi. The seasonal nature of this disease has been noted by many researchers. The aim of the study was to elucidate processes involved in epidermal hyperplasia regeneration of koi carp which occurs during a steady temperature increase. In the study 14 immature male koi carps, divided into 7 affected and 7 healthy fish, with the body weight of 130–450g were observed. The koi carps were raised in cages with the water temperature of 9ºC which was raised up to 18.5 ºC. Fish health condition and alterations of cellular structure during epidermal regeneration were studied by the means of visual observation, routine histology and histochemistry, morphometric analysis during 78 days. Erosion and desquamation, beginning from the line of new epidermis (newly differentiated mucous cell line), was noted at the final phase of regression of epidermal hyperplasia.Our investigations showed clear interrelation between epidermal regeneration and the number of club cells.
