| Abstract |
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 accumulation of carbohydrate material occurs in the outermost layer of epidermal cells. There is a change in the carbohydrate composition or structure in the dermal layers at the site of injury. The basal epidermal cells rapidly divide in the in-vitro culture whereas only those basal epidermal cells in an in-vivo injury in close proximity to the injury divide. The surrounding nutrient medium in in-vitro cultures does not appear to be involved in the initial cell migration. However, ascorbic acid does stimulate epidermal migration, mucous secretion, and basal epidermal cell mitosis. |
