Este protocolo demonstra as diferentes etapas na geração e isolamento de células gliais a partir de células embrionárias humanas usando SDIA. A aplicação deste método é múltiplo e tem sido usado em muitos protocolos para a produção de neurônios especificado (por exemplo, 1, 2, 5-9). O rosetas são pensadas para se parecer com as células do tubo neural com um fenótipo anterior (2, 5, 10) e também contêm progenitores da crista neural (11, 12). Além disso, eles mantêm um certo nível de plasticidade, uma vez que podem ser mo...

es cell-derived neuroepithelial cell cultures

Células-tronco embrionárias têm o potencial de se diferenciar em células de todas as camadas germinativas, o que os torna uma ferramenta atraente para o desenvolvimento de novas terapias. Em geral, a diferenciação de células-tronco embrionárias segue o conceito para a primeira geração de células progenitoras imaturas, que depois podem ser propagadas e diferenciado em fenótipos maduros celular. Isto também se aplica para o ES neurogênese células derivada, em que o desenvolvimento de células neurais segue duas etapas principais: Primeiro, a derivação ea expansão de precursores imaturos neuroepiteliais e, segundo, sua diferenciação em células maduras neural. Um método comum para a produção de progenitores neurais a partir de células ES é baseado em embrióides corpo formação (EB), que revela a diferenciação das células de todas as camadas germinativas incluindo neuroectoderma. Um método alternativo e mais eficiente para induzir o desenvolvimento de células neuroepiteliais usa actividade indutora do estroma de células derivadas (SDIA), que pode ser alcançado pelas células de cultura co-ES com o osso do crânio derivadas da medula células do estroma (1). Tanto, a formação de EB e SDIA, revelam o desenvolvimento de rosette-como estruturas, que são pensados ​​para assemelhar-se do tubo neural e / ou da crista neural, como progenitores. Os precursores neurais podem ser isoladas, expandidas e ainda mais diferenciado em neurônios e células gliais específicos usando condições de cultura definidas. Aqui, descrevemos a produção e isolamento de rosetas como em co-cultura experimentos com a linhagem de células do estroma MS5 (2-5).
