A method for large-scale production of mouse brain cortical cultures

Fetal cerebral cortex can be grown for several weeks in dissociated cell culture using a relatively simple protocol for culture preparation. It is possible to establish large numbers of very similar cultures which serve as an effective test system for studies of toxicity and mechanism of action of neuroactive compounds. Light microscopic and ultrastructural studies document the neuronal component of the cultures as well as the developmental sequence. Cell counts, protein concentration and choline acetyltransferase activity demonstrate the reproducibility of the cultures from dish to dish.
