Summary

Descriviamo l’isolamento immunomagnetica degli oligodendrociti primario del mouse, che permette l’isolamento rapido e specifico delle cellule per coltura in vitro .

Abstract

L’efficiente e robusto isolamento e coltura dei oligodendrocytes primario (OLs) è uno strumento prezioso per lo Studio in vitro di sviluppo di oligodendroglia, nonché la biologia di demyelinating malattie come la sclerosi multipla e Malattia di Pelizaeus-Merzbacher-simile (PMLD). Qui, presentiamo un semplice e metodo di selezione efficace per l’isolamento di immunomagnetica di fase tre O4⁺ cellule preoligodendrocytes da cuccioli di topi neonatali. Poiché immaturo OL costituiscono più dell’80% della materia bianca roditore-cervello postnatale giorno 7 (P7) questo metodo di isolamento non solo assicura un alto rendimento cellulare, ma anche l’isolamento specifico di OLs già commesso alla stirpe oligodendroglial, diminuendo il possibilità di isolare cellule contaminanti quali gli astrociti e altre cellule del cervello del mouse. Questo metodo è una modifica delle tecniche segnalato precedentemente e fornisce del oligodendrocyte preparazione purezza superiore al 80% in circa 4 h.

Introduction

Oligodendrociti (OLs) sono le cellule di mielinizzazione del sistema nervoso centrale (SNC)¹. L’isolamento e la coltura degli oligodendrociti primari in un ambiente strettamente regolamentato è uno strumento prezioso per lo Studio in vitro di sviluppo di oligodendroglia, nonché la biologia di demyelinating malattie come la sclerosi multipla². Ciò richiede un’efficiente e robusto del oligodendrocyte isolamento e coltura metodo³. In questo studio, abbiamo approfittato dell’espressione di un indicatore della superficie delle cellule del oligodendrocyte distintivo per implementare una tecnica di isolamento modificate che è rapido e specifico.

Sono state identificate quattro distinte fasi di maturazione del oligodendrocyte, ognuna caratterizzata dall’espressione di marcatori di superficie cellulare distintivo per ogni stadio di sviluppo (Figura 1). Questi indicatori di superficie delle cellule possono essere riconosciuti da anticorpi specifici⁴^,⁵e possono essere utilizzati per isolare OLs alle fasi specifiche. Nella prima fase, le cellule del precursore del oligodendrocyte (OPCs) hanno la capacità di proliferare, migrare e rapidi in particolare fattore di crescita derivato dalle piastrine (PDGF-Rα) recettore⁶, ganglioside A2B5, proteoglicano NG2⁷^,⁸, neuro-acido polisialico delle cellule adesione molecola⁹ e grassi-acido-legante proteina 7 (FABP7)¹⁰. Gli OPC hanno morfologia bipolare con alcuni processi brevi che emana dai poli opposti del corpo cellulare, che è caratteristico di cellule precursori neurali¹¹.

Figura 1: espressione di marcatori di superficie delle cellule durante lo sviluppo del oligodendrocyte mouse. OLs cella marcatori di superficie come A2B5, GalC (O1), NG2, O4 e PDGF-Rα può essere utilizzato per isolare specificamente oligodendrociti in fase inerente allo sviluppo specifica utilizzando anticorpi specifici. Clicca qui per visualizzare una versione più grande di questa figura.

Nella seconda fase, OPCs danno luogo a preoligodendrocytes e rapidi alla membrana delle cellule non solo gli indicatori OPC, ma anche il sulfatide (un galattolipide solfonata) riconosciuto dal O4 anticorpo¹²^,¹³e la proteina GPR17¹⁴, che persiste fino alla fase di oligodendrociti immaturi (OL). In questa fase, preoligodendrocytes estendere multipolari processi brevi. Preoligodendrocytes sono la grande fase OL al giorno postnatale 2 (P2) nella materia bianca cerebrale di ratto e topo con una popolazione secondaria di immaturi OLs¹⁵.

Durante la terza tappa, immaturi OLs continuano a esprimere O4, perdere espressione degli indicatori A2B5 e NG2 e cominciano ad esprimere Galattocerebrosidi C¹⁶. In questa fase, OLs sono impegnati alla stirpe oligodendroglial e diventare cellule post-mitotiche con rami lunghi ramificate¹⁷^,¹⁸. Immaturo OL costituiscono più dell’80% della materia bianca del roditore in P7 e in questo momento si osservano le prime cellule MBP⁺ ¹⁵^,¹⁹^,²⁰^,²¹. Di conseguenza, isolamento di OLs presso P7 potrebbe garantire alto rendimento cellulare.

Nella fase finale e la quarta di sviluppo OL, OLs matura esprimono proteine myelinating (proteina basica della mielina (MBP), proteolipide (PLP), glicoproteina mielina associata (MAG) e myelin oligodendrocyte glycoprotein (MOG)²²^,²³ ^,²⁴^,²⁵^,²⁶. In questa fase, OLs matura estendere membrane quello compatto di forma economale guaine intorno gli assoni e sono in grado di mielinare. Questo coincide con l’osservazione che nel cervello di ratto e topo, cellule MBP⁺ diventano sempre più abbondanti a P14¹⁹^,²⁰^,²¹.

Poiché il primo isolamento del oligodendrocyte Fewster e colleghi nel 1967²⁷, sono stati implementati diversi metodi per l’isolamento di OLs da roditore SNC compreso immunopanning²⁸^,²⁹^,³⁰, fluorescenza-attivato delle cellule ordinano (FACS) sfruttando delle cellule degli antigeni di superficie-specific²⁸^,³¹, differenziale mediante centrifugazione in gradiente³²^,³³^,³⁴^,³⁵e agitazione metodo basato sull’adesione differenziale di diverse CNS glia³⁶^,³⁷. Tuttavia, i metodi di coltura esistenti hanno limitazioni, soprattutto in termini di purezza, rendimento e tempo necessario per eseguire la procedure³⁸. Pertanto, i metodi più efficienti di isolamento per gli oligodendrociti sono necessari.

In questa carta, presentiamo un semplice e metodo di selezione efficace per l’isolamento di immunomagnetica di fase tre O4⁺ cellule preoligodendrocytes da cuccioli di topi neonatali. Questo metodo è una modificazione delle tecniche riportate da Emery et al. ³⁹ e Dincman et al. ⁴⁰ e fornisce una purezza di preparazione del oligodendrocyte superiore all’80% in circa 4 h.

Protocol

I topi utilizzati in questo studio sono stati curati per secondo le indicazioni del numero di protocollo di SUNY Downstate Medical Center divisione del laboratorio animale risorse (DLAR) 15-10492. Nota: Oligodendrocytes primario sono stati isolati da neonatale (P5-P7 selvaggio-tipo C57Bl/6N) topi. In questa fase, immaturi OLs costituiscono più dell’80% della materia bianca del roditore garantire alto rendimento cellulare. Tutti i buffer e composizioni di reagente sono disponibili alla fine de…

Representative Results

Lo scopo di questo studio era di stabilire un metodo di isolamento migliorato per O4+ oligodendrociti primario del mouse che richiedono la manipolazione meno possibile delle cellule bersaglio. L’intera procedura dall’eutanasia dei cuccioli di placcatura delle celle di vetrini coprioggetti prende circa 4 h e i dati qui indicati rappresentano tre esperimenti indipendenti. Dopo dissociazione del tessuto, una media di 4,3 ± 0,46 x 107 cellule sono state isolate per ogni…

Discussion

In questa comunicazione, presentiamo un metodo per l’isolamento efficiente delle culture del oligodendrocyte altamente purificata del mouse immaturo. Rispetto ai protocolli precedentemente pubblicati³⁹^,⁴⁰, questo metodo ha reso una purezza più elevata con un livello molto più basso degli astrociti GFAP-positive e una percentuale molto bassa di altre cellule non caratterizzato. È importante sottolineare che questi sono immaturi OLs già commit alla stirpe oligo…

Adjust the pH of the buffer while stirring to 0.1-0.3 units below pH= 7.4 since it may rise during filtration. The use of 1N HCl or 1N NaOH is recommended to adjust the pH. 8. Add additional water to bring the final volume to 1L. 9. Sterilize by filtration using a membrane with a porosity of 0.22 microns. 10. Store at 2-8 °C.
