Este protocolo é baseado em modificações de procedimentos que têm sido descritos na 3,7,11 passado. Há vários pontos importantes a considerar como discutido abaixo. Os neurônios granulares e células progenitoras aderir dentro de 2 horas de placas. Células saudáveis ​​têm uma morfologia redonda sob o microscópio de contraste de fase 4. Dentro de 24 horas após o plaqueamento, as células saudáveis ​​vai se espalhar uniformemente ao redor as lamelas ou o bem de plástico e formarão processos...

isolation and culture of post-natal mouse cerebellar granule neuron progenitor cells and neurons 

O córtex cerebelar é uma estrutura bem descrito que oferece oportunidades únicas para o estudo das propriedades neuronais e 1,2 de desenvolvimento. Dos tipos cerebelar neuronal (células granulares, células de Purkinje e interneurônios inibitórios), neurônios granulares são de longe os mais numerosos e são o tipo mais abundante de neurônios no cérebro de mamíferos. Em roedores, os neurônios granulares do cerebelo são gerados durante as duas primeiras semanas pós-natal a partir de células progenitoras na camada mais externa do córtex cerebelar, a camada granular externa (EGL). O protocolo aqui apresentado descreve técnicas para enriquecer e neurônios granulares cultura e suas células progenitoras da pós-natal do cerebelo de rato. Iremos descrever os procedimentos para obter culturas de pureza aumentando 3,4, o que pode ser usado para estudar a diferenciação de proliferação de células progenitoras em neurônios granulares 5,6. Uma vez que as células progenitoras diferenciar, as culturas também proporcionam uma população homogênea de neurônios granulares para manipulação experimental e caracterização de fenômenos como a sinaptogênese, a função de receptor de glutamato 7, interação com outras células purificadas cerebelar 8,9 ou morte celular 7.
