【Abstract】 Objective\ To explore an optimal "microisland" primary culture method for dopaminergic neuron from postnatal rat ventral midbrain, and to investigate the effects of different medium for maintaining neuron survival and growth.\ Methods\ "Microisland" culture technique used agarose as a substrate that was virtually non\|adhesive for glial cells, then droplets of collagen were applied to this non\|adhesive surface in order to provide a consistent and uniform substrate for glial attachment.\ Glial feeder layers were estabilished and then the neurons from postnatal rat midbrain were cultured on the "microisland".\ Results\ "Microislands" made one or several dopaminergic neurons growing in a small area, isolated from other neurons.\ A much higher frequency of synaptic connection could be achieved in "microisland" co\|cultures.\ Conclusion\ "Microisland" culture medium of dopaminergic neuron from ventral midbrain are established.\ It can be a new cellular model for studying dopaminergic neuron.\;更多还原
