Is the brain of cherri salmon Oncorhynchus masou a new model for investigation of postembryonic neurogenesis?
The data of our investigations contribute to understanding of cellular mechanisms of the teleost fishes CNS forming in postembryonic development.The revealed peculiarities of structural and neurochemical organization and description of basic histogenetic processes (proliferation,migration and neuronal cell differentiation) during the brain forming in fish,which have signs of fetal organization,widen the existing knowledge about histogenesis of these structures in postembryonic development.It seems conceivable,that during postembrional development in teleost fishes some neurotransmitters and gaseous mediators (NO and H2S) act as factors,which initiate and regulate the cellular and the tissues processes of genetic program during the brain development.Materials of this investigation define a new experimental model for studying of postembrional neurogenesis processes.
