In deze studie hebben we een eenvoudige en effectieve methode voor neuronale differentiatie van mESCs vastgesteld, met lage kosten en gemakkelijk te verkrijgen materialen. Bij deze methode kunnen 2 dagen embryoide lichaamsvorming gevolgd door 6 dagen RA-inductie de differentiatie van mESC's in NPC's effectief bevorderen (fase I-protocol 3). Voor de fase II-differentiatie induceert N2B27 medium II (Fase II-protocol 3) het meest effectief de differentiatie van NPC's in neuronen. Om succes te garanderen, moet meer aandacht ...

Embryonale stamcellen (ECC's) zijn pluripotent en kunnen zich onder bepaalde omstandigheden onderscheiden in neurale precursorcellen (NPC's) en vervolgens in neuronen1. ESC-gebaseerde neurogenese biedt het beste platform om neurogenese na te bootsen, en dient zo als een nuttig hulpmiddel voor ontwikkelingsbiologische studies en mogelijk hulp bij regeneratieve geneeskunde2,3. In de afgelopen decennia zijn veel strategieën gerapporteerd voor het induceren van embryonale neurogenese, zoals de transgene methode4, met behulp van kleinemoleculen 5, met behulp van een 3D-matrix micromilieu6, en de co-cultuurtechniek7. De meeste van deze protocollen zijn echter beperkt of moeilijk te bedienen, dus ze zijn niet geschikt voor gebruik in de meeste laboratoria.
Om een eenvoudig te bedienen en goedkope methode te vinden om efficiënte neurale differentiatie van mESCs te bereiken, werd hier een combinatorische screeningstrategie gebruikt. Zoals beschreven in figuur 1,was het hele proces van embryonale neurogenese verdeeld in 2 fasen. Fase I verwijst naar het differentiatieproces van mESC's naar NPC's, en fase II heeft betrekking op de daaropvolgende differentiatie van NPC's in neuronen. Op basis van de principes van eenvoudige bediening, lage kosten, gemakkelijk beschikbare materialen en een hoge differentiatie-efficiëntie, werden zeven protocollen in fase I en drie protocollen in fase II gekozen op basis van het traditionele aanhankelijke monolaagcultuursysteem of embryooïde lichaamsvormingssysteem8,9. De differentiatie-efficiëntie van protocollen in beide fasen werd geëvalueerd met behulp van celmorfologieobservatie en immunofluorescentietest. Door het meest efficiënte protocol van elke fase te combineren, hebben we de geoptimaliseerde methode voor neurale differentiatie van mESCs vastgesteld.

neuronal differentiation from mouse embryonic stem cells in vitro

De neurale differentiatie van embryonale stamcellen van muizen (mESCs) is een potentieel hulpmiddel om de belangrijkste mechanismen die betrokken zijn bij neurogenese op te helderen en mogelijk te helpen bij regeneratieve geneeskunde. Hier hebben we een efficiënte en goedkope methode voor neuronale differentiatie van mESCs in vitroopgezet, met behulp van de strategie van combinatorische screening. Onder de hier gedefinieerde omstandigheden maakt het 2-daagse embryoide lichaamsvorming + 6-daags retinoïnezuurinductieprotocol een snelle en efficiënte differentiatie van mESCs in neurale precursorcellen (NPC's) mogelijk, zoals blijkt uit de vorming van goed gestapelde en neurietachtige A2lox en 129 derivaten die Nestine-positief zijn. De gezonde toestand van embryonale lichamen en het tijdstip waarop retinoïnezuur (RA) wordt toegepast, evenals de RA-concentraties, zijn daarbij van cruciaal belang. In de daaropvolgende differentiatie van NPC's in neuronen zou N2B27 medium II (aangevuld met Neurobasal medium) het onderhoud en de rijping van neuronale cellen op lange termijn beter kunnen ondersteunen. De gepresenteerde methode is zeer efficiënt, goedkoop en eenvoudig te bedienen en kan een krachtig hulpmiddel zijn voor neurobiologie en ontwikkelingsbiologieonderzoek.

2-daagse embryoide lichaamsvorming + 6-daagse RA-inductie werkt het beste bij het sturen van de differentiatie van mESC's naar NPC's (fase I). Om het optimale protocol te bepalen dat de differentiatie van mESCs in NPC's (Fase I) het beste bevordert, werden 7 protocollen getest op zowel A2lox als 129 mESCs (tabel 1) en werd de differentiatiestatus van elke groep gecontroleerd met behulp van een lichtmicroscoop. Zoals getoond in figuur 3A, vertoonden de meeste A2lox en 129 der...
