Abstract
Dissociated cells from embryonic mouse brain reassociate in rotation culture to form aggregates. During cell culture the specific activities of choline acetyl-transferase (EC 2.3.1.6), acetylcholinesterase (EC 3.1.1.7), and glutamate decarboxylase (EC 4.1.1.15) in the aggregates increase up to twenty-fold, a phenomenon that approximates some of the biochemical events in the development of the mouse brain.
Keywords: morphology, enzyme assays, mouse embryo
