AGS cellule staminali adulte neurali sono robusti e può essere ampliato per numerosi passaggi che li rende una fonte eccellente di cellule staminali neurali per lo studio delle proprietà delle cellule staminali neurali di base. Il tasso di espansione è di circa un raddoppio ogni 24 ore, ma queste cellule devono essere diversi passaggi prima di confluenza raggiungere perché il contatto tra le cellule favorirà la differenziazione di astrociti. Contatto mediato differenziazione quindi causa il rapporto tra i neuroni a...

growth and differentiation of adult hippocampal arctic ground squirrel neural stem cells

Scoiattoli artici (Urocitellus parryii, AGS) sono unici nella loro capacità di letargo con una temperatura interna del corpo vicino o sotto lo zero 1. Questi animali anche resistere al danno ischemico cerebrale in vivo 2,3 e deprivazione di ossigeno e glucosio in vitro 4,5. Queste qualità uniche fornito l&#39;impulso di isolare i neuroni AGS di esaminare le caratteristiche intrinseche dei neuroni che potrebbe spiegare la capacità dei neuroni AGS a resistere lesioni e la morte cellulare causata da ischemia e temperature estremamente fredde. L&#39;identificazione delle proteine ​​o obiettivi gene che consentono le proprietà distintive di queste cellule potrebbero essere di aiuto nella scoperta di terapie efficaci per una serie di indicazioni ischemica e per lo studio della resistenza al freddo. Adulto ippocampo AGS contiene cellule staminali neurali che continuano a proliferare, consentendo una facile espansione di queste cellule staminali in coltura. Descriviamo qui i metodi con cui i ricercatori possono utilizzare queste cellule staminali e neuroni differenziati per qualsiasi numero di scopi. Da seguire con attenzione questi passaggi il neurali cellule staminali AGS può essere espansa attraverso due o più passaggi e poi differenziato a una cultura ad alto contenuto di TUJ1-positivi neuroni (~ 50%) senza utilizzare sostanze chimiche tossiche per minimizzare il numero di cellule in divisione. Ischemia induce neurogenesi 6 e neurogenesi che procede attraverso MEK / ERK e percorsi di sopravvivenza PI3K/AKT segnalazione contribuisce alla resistenza ischemia in vivo in vitro 7 e 8 (Kelleher-Anderson, Drew et al., In preparazione). Un&#39;ulteriore caratterizzazione di queste cellule neurali unica possibile anticipo su molti fronti, utilizzando alcuni o tutti questi metodi.
