Dit protocol is gebaseerd op de wijzigingen van de procedures die zijn beschreven in het verleden 10,11. Naast de voormalige publicaties we hier laten zien van de individuele verschillende stappen van het proces meer uitgebreid. Dit ondersteunt de onderzoeker met belangrijke gegevens te verzekeren de juiste procedures en betrouwbare resultaten. Verder, als de dissectie proces is een essentieel onderdeel van CEE extractie beschrijven we de procedure voor het nemen van de embryo&#39;s uit de dooierzak in elk de...

production of chick embryo extract for the cultivation of murine neural crest stem cells

De neurale lijst komt voort uit het neuro-ectoderm tijdens de embryogenese en blijft slechts tijdelijk. Vroege experimenten al ondoorlaatbaar pluripotente voorlopercellen naar een integraal onderdeel van de neurale lijst 1. Fenotypisch, zijn neurale stamcellen (NCSC) gedefinieerd door gelijktijdig te drukken p75 (low-affiene zenuw groeifactor receptor, LNGFR) en SOX10 tijdens hun migratie van de neurale lijst 2,3,4,5. Deze stamcellen kunnen differentiëren in gladde spiercellen, chroomaffiene cellen, neuronen en gliacellen, evenals melanocyten, kraakbeen en bot 6,7,8,9. Te cultiveren NCSC in vitro, een speciale neurale stamcellen medium (NCSCM) is vereist 10. Het meest complexe deel van de NCSCM is de voorbereiding van de kippenembryo extract (CEE) die een essentiële bron van groei factoren voor de NCSC als voor andere vormen van neurale explantaten. Andere NCSCM ingrediënten naast CEE zijn commercieel verkrijgbaar. Het produceren van CCE met behulp van laboratorium-standaard uitrusting is het van groot belang om te weten over de uitdagende details zoals de isolatie, maceratie, centrifugeren en filtratie processen. In dit protocol beschrijven we accurate technieken om een ​​maximale hoeveelheid van pure en hoge kwaliteit CEE te produceren.
