A vantagem de 2-5 murino organotípicas culturas de retina wholemount mais de dissociação, monocamada, retinospheroid ou re-agregados 3D culturas esferóide 1 encontra-se na preservação de interações e conexões neuronais, simulando a situação in vivo. Em comparação com os relatórios anteriores 2, o nosso artigo de vídeo oferece uma demonstração detalhada das peculiaridades em enucleação dos olhos murino e dissecção de retinas de diferentes estágios d...

in vivo-like organotypic murine retinal wholemount culture

Ablações alvo de genes e análise de modelos animais é a estratégia clássica para se matricular a função do gene específico da retina. No entanto, transgênicos, modelos de mouse retina específicos ou condicional knockout freqüentemente exibem letalidade precoce ou sofrem de malformações graves, impedindo uma análise para além embrionárias ou início de estágios pós-natal. Cultura de células primárias é uma alternativa para investigar os efeitos da aplicação exógena fatores recombinantes, superexpressão de genes ou siRNA mediada knockdown do gene em um ambiente controlado. Cultura de células dissociadas tem a vantagem de que os sinais endógenos atingindo as células-alvo são reduzidos, facilitando assim a identificação de exogenamente efeitos desencadeados após manipulação farmacológica. No entanto, importantes interações célula-célula são inicialmente destruída por digestão enzimática ou dissociação mecânica, mesmo se re-agregados culturas retinospheroid 1 são utilizados. Pelo contrário, organotípicas retina culturas wholemount fornecer um sistema próximo ao fisiológico situação in vivo com as interações e conexões neuronais 2-5 ainda preservada. Neste artigo apresentamos uma video passo a passo de demonstração (1) o estabelecimento de in vivo da retina-como organotípicas culturas wholemount incluindo peculiaridades dissecção da embrionárias, pós-natal e adulto olhos murino e (2) um procedimento de dissociação e cytospin para análise de neuronal apoptose e proliferação das células da retina em wholemounts organotípicas, por exemplo, após a cultura na presença de fatores aplicada exogenamente recombinante.
