Il vantaggio di murine organotipica retina 2-5 wholemount culture più di dissociazione, monostrato, culture 3D retinospheroid o ri-aggregati sferoidali 1 risiede nella conservazione delle interazioni e connessioni neuronali, imitando la situazione in vivo. Rispetto ai rapporti precedenti 2, il nostro articolo video fornisce una dimostrazione dettagliata delle peculiarità di enucleazione degli occhi murini e la dissezione di retine di varie fasi di sviluppo tra cui la rimozione...

in vivo-like organotypic murine retinal wholemount culture

Ablazioni mirata di geni e l&#39;analisi di modelli animali è la strategia classica per la funzione dell&#39;iscrizione gene specifico della retina. Tuttavia, transgenici, retina specifici o condizionale modelli di topo knockout spesso mostrano mortalità precoce o soffre di malformazioni gravi, impedendo l&#39;analisi al di là fasi embrionali o postnatale precoce. Colture di cellule primarie è un&#39;alternativa per studiare gli effetti di fattori applicata ricombinante esogena, l&#39;iperespressione di geni o di siRNA-mediato knockdown gene in un ambiente controllato. Colture di cellule dissociate ha il vantaggio che i segnali endogeni raggiungere le cellule bersaglio sono ridotte, facilitando l&#39;identificazione di effetti esogenamente attivato dopo manipolazione farmacologica. Tuttavia, importanti interazioni cellula-cellula sono inizialmente distrutte per digestione enzimatica o dissociazione meccanica, anche se le culture retinospheroid riaggregati 1 sono utilizzati. Al contrario, organotipica culture retina wholemount fornire un sistema vicino al fisiologico in situazione vivo con le interazioni e le connessioni neuronali 2-5 ancora conservati. In questo articolo abbiamo video di fornire una dimostrazione passo passo (1) l&#39;istituzione di in vivo, come organotipica culture wholemount della retina, comprese particolarità dissezione degli occhi murini embrionale, postnatale e adulta e (2) una procedura di dissociazione e cytospin per l&#39;analisi dei neuroni apoptosi e la proliferazione delle cellule della retina in wholemounts organotipica, ad esempio dopo coltura in presenza di fattori esogeni applicata ricombinante.
