Il metodo di dissezione e cultura di neuroni ippocampali di ratto e corticale qui descritto permette di eseguire esperimenti utilizzando colture neuronali quasi purezza coltivate in un mezzo chimicamente definito (Figura 3). Anche se i protocolli per i neuroni coltura quasi pura nel siero senza supporti sono stati precedentemente descritti 2,3,4, ci sono importanti cambiamenti nel nostro metodo. Diverso da protocolli tradizionali (vale a dire Banker et al.) 5, abbiamo sostituito tr...

isolation and culture of rat embryonic neural cells: a quick protocol

Stiamo descrivendo un metodo rapido di dissociarsi e di cultura neuroni dell&#39;ippocampo o corticale da E15-17 embrioni di ratto. La procedura può essere applicata con successo per l&#39;isolamento del mouse e neuroni umani primari e progenitori neurali. Neuroni dissociati sono mantenuti in terreno privo di siero fino a diverse settimane. Queste colture possono essere utilizzati per nucleofection, immunocitochimica, acidi nucleici preparazione, nonché elettrofisiologia. Vecchi colture neuronali possono anche essere trasfettate con un tasso di buona efficienza di trasduzione lentivirale e, meno efficiente, con fosfato di calcio o base di lipidi metodi come lipofectamina.
