Fish Primary Cultures For Toxicity And Pathological Studies, Maria Lyons Alcantara

Doctoral

In this study, epithelial primary cultures from the rainbow trout (Oncorhynchus mykiss) were developed as a model for environmental effects assessment. Cadmium was used as representative of heavy metals. The possible use of this system for pathological studies was also evaluated. The differential cytotoxic effects of cadmium on fish and mammalian epithelial cells in established and primary culture wee assessed by looking at the reduction of colony-forming ability and the reduction in the extent of growth. The influence of medium composition on the toxicity of cadmium was also studied using serum-free and serum-containing media. The experiments using immortalised cell lines …
