Abstract:
The ultrastructure of dissociated brain nerve cells from embryonic chicken cult ivated in vitro was studied both under SEM and TEM. Primitive synaptic junctions among the bipolar and multipolar neuronal cell bodies and its processes forming networks of fibers appeared after 4 days of culture. The presynaptic bags and desmosome-like cell junctions were observed simutaneously. Axo-dendritic, axo-somatic and axo-axonal synapses increased in number after 7 days of incubation onwards. Neuronal degeneration and proliferation of fibrous glial cells were evident in10 and 14 days cultures.
