Title:
Evaluation of the V79 cell metabolic co-operation assay as a screen in vitro for developmental toxicants
Author:
Toraason M, Bohrman JS, and Krieg E
Year:
1992
Bibliographic source:
Toxic. in Vitro 6, 165-174

Materials and methods

Principles of method if other than guideline:
Phthalimide was tested for its effect on intercellular communication in the V79 cell metabolic co-operation assay (as inhibition of intercellular communication is proposed to be one of several possible mechanisms of teratogenesis, the V79 cell metabolic co-operation assay is evaluated as a in vitro screen for developmental toxicants).
GLP compliance:
not specified
Type of method:
in vitro
