Early Stages in the Recovery to Injury in the Dorsal Fin of the Atlantic Cod ( Gadus morhua )
The early stages in the recovery of the dorsal fin of the Atlantic cod (Gadus morhua) to a "clean cut injury" are described. It is concluded that the observed rapid epidermal migration, wound closure and cell mitosis are essentially the same in in-vivo as in in-vitro experiments. An accumu...
