Abstract (en)

[origin: WO2015135893A1] The invention relates to neuronal cell culturing methods, to the use therof and to cell cultures produced accordingly. The invention relates more particularly to a method for producing a neuronal planar cell culture by carrying out preliminary differentiation of stem cells, e.g. human induced pluripotent stem cells, in a three-dimensional cell assembly which comprises at least two regions corresponding to different regions of the brain, and which is termed a cerebral organoid, and taking progenitor cells from a region corresponding to a defined brain region, and carrying out further culturing on a planar support, e.g. an MEA neurochip. This produces a neuronal planar cell culture in which the cells form a neuronal network and have an electrical or electrophysiological activity which is specific for the defined brain region. A cell culture of this kind may be used, for example, in high-throughput screening for testing substances for neurological activity.
