Presentato qui è un protocollo per la generazione di una coltura unicellulare di cellule staminali embrionali umane e la loro successiva differenziazione in cellule progenitrici neurali. Il protocollo è semplice, robusto, scalabile e adatto per lo screening farmacologico e le applicazioni di medicina rigenerativa.

Le cellule staminali embrionali umane possono essere indotte a differenziarsi in cellule progenitrici neurali e successivamente in astrociti neuronali e oligodendrociti. Tuttavia, il metodo di coltura del tipo per le cellule staminali embrionali umane e la loro differenziazione in cellule progenitrici neurali sono un sistema di co-coltura in vivo molto inefficiente e aperto Qui presentiamo un sistema di coltura migliorato e robusto che è facilmente scalabile utilizzando coltura di tipo a singola cellula ad alta densità con cellule staminali embrionali umane. La coltura di tipo a singola cellula delle cellule staminali embrionali umane fornisce un sistema rapido ed efficiente per studiare i meccanismi molecolari che regolano la differenziazione in più fasi lungo vari e distinti lignaggi differenziati, comprese le cellule progenitrici neurali e la loro successiva differenziazione in ulteriori lignaggi neurali.

Inizia preparando piastre rivestite a matrice di membrana basale qualificate per cellule staminali embrionali umane. Scongelare lentamente la soluzione a matrice di membrana basale a quattro gradi Celsius per almeno due o tre ore o durante la notte. Una volta scongelata, diluire la matrice in DMEM/F-12 freddo e mescolare bene dal 12% al 2% e rivestire ogni pozzetto di una piastra a sei pozzetti con un millilitro della soluzione diluita.
