Cellule staminali neurali raccolte dal cervello adulto sono in aumento utilizzati in applicazioni che vanno dalla ricerca di base dello sviluppo del sistema nervoso ad esplorare potenziali applicazioni cliniche in medicina rigenerativa. Questo rende rigoroso controllo delle condizioni di isolamento e di coltura utilizzate per coltivare queste cellule fondamentali per suonare i risultati sperimentali.

L'obiettivo generale del seguente esperimento è quello di generare colture di cellule staminali neurali da diverse aree del cervello del roditore adulto. Ciò si ottiene raccogliendo tessuto da una regione di interesse per esaminare la presenza e il potenziale delle cellule staminali neurali. In una seconda fase, trasformare il tessuto in una sospensione cellulare per la piastratura come coltura monostrato.

Successivamente, utilizzare le condizioni di coltura definite per propagare selettivamente le cellule staminali neurali, convalidando il loro potenziale di auto-rinnovamento. Si ottengono risultati in vitro che dimostrano che le cellule staminali neurali sono multipotenti in base al loro potenziale di differenziazione e come vari fattori possono influenzare il loro autorinnovamento e il loro destino. Questo metodo può aiutare a rispondere a domande chiave nel campo delle neuroscienze e della medicina rigenerativa, come ad esempio dove risiedono le cellule neurostaminali endogene e come manipolarle.
