摘要: Organotypic cocultures of striatum, cortex, and ventral mesencephalon were used to study the anatomical physiological development striatal neurons in presence or absence cortical nigral (SN/VTA) inputs. Striatum cortex dissected from prenatal (E18-E22) early postnatal (P0-P2) rats, SN/VTA was E14-15 fetuses; pieces maintained up 3 weeks static slice culture. Triple containing exhibited rapid robust dopamine (DA) innervation striatum a patchy pattern, homogeneous distribution within piece, regardless orientations three pieces. DA fibers piece overlapped patch neurons, marked by DARPP-32 immunoreactivity, cultures prepared all age but most analogous that seen vivo observed with use late (E20-E22) striatum. The patch/matrix organization nigrostriatal afferents. In addition, more complete transition E18/19 innervation. Electrophysiological recording demonstrated both spontaneous cortically evoked activity medium spiny neurons; this greatly influenced These findings demonstrate importance afferent maturation organotypic cultures.
