Metodi 1. Preparazione delle cellule Come esempio, descriveremo la procedura per la preparazione di cellule progenitrici gliali 12 per il trapianto a causa della nostra esperienza con questo tipo di cellule. Tuttavia, le specifiche del protocollo, tra cui media e l&#39;uso di tripsina per esempio, dipende dal tipo di cellula particolare utilizzato per il trapianto. <ol><li> Pre-caldo tutte le soluzioni al 37,0 ° C a bagnomaria. </li><li> Risciacquare 2...

Per gli studi che coinvolgono topi G93A SOD1 e ratti, età e sesso-match degli animali all&#39;interno di un gruppo, e distribuire animali all&#39;interno della stessa cucciolata a gruppi diversi. E &#39;preferibile utilizzare tutti gli animali del sesso stesso per entrambi i modelli di SLA e SIC, perché i processi di malattia possono differire tra maschi e femmine, tuttavia, può anche essere utile avere abbastanza animali da entrambi i sessi per individuare possibili sesso-specifici effetti, come questo fe...

intraspinal cell transplantation for targeting cervical ventral horn in amyotrophic lateral sclerosis and traumatic spinal cord injury

Compromissione respiratoria a causa della perdita dei motoneuroni frenico è una conseguenza debilitante di gran parte delle risorse umane lesioni traumatiche del midollo spinale (SCI) casi 1 ed è la causa ultima di morte nei pazienti con la malattia del motoneurone, sclerosi laterali amiotrofica (SLA) 2. La SLA è una malattia neurologica devastante che è caratterizzata da degenerazione relativamente rapido di neuroni motori superiori ed inferiori. I pazienti alla fine soccombere alla malattia in media 2-5 anni dopo la diagnosi a causa della paralisi respiratoria a causa della perdita dei motoneuroni innnervation frenico del diaframma 3. La stragrande maggioranza dei casi sono sporadici, mentre il 10% sono della forma familiare. Circa il venti per cento dei casi familiari sono legati a mutazioni puntiformi diverse nel Cu / Zn superossido dismutasi 1 (SOD1) del gene sul cromosoma 21 4. Topi transgenici 4,5 e 6 ratti trasporto umano SOD1 mutante geni (G93A, G37R, G86R, G85R) sono stati generati, e, nonostante l&#39;esistenza di altri modelli animali di perdita dei motoneuroni, sono attualmente i modelli più utilizzati altamente della malattia . Lesioni del midollo spinale (SCI) è un insieme eterogeneo di condizioni derivanti da traumi fisici al midollo spinale, con risultato funzionale variabile a seconda del tipo di posizione, e la gravità delle lesioni 7. Tuttavia, circa la metà dei casi umani SCI influenzare regioni cervicale, con conseguente debilitante disfunzioni respiratorie a causa di frenico perdita di neuroni motori e lesioni a discendente assoni respiratorie bulbospinal 1. Un certo numero di modelli animali di SCI sono stati sviluppati, con i più usati e clinicamente rilevanti è la contusione 8. Il trapianto di varie classi di cellule precursori neurali (NPC) è una promettente strategia terapeutica per il trattamento di lesioni traumatiche del SNC e neurodegenerazione, tra SLA e SCI, a causa della possibilità di sostituire neuroprotezione persi o SNC disfunzionale tipi di cellule, fornire e distribuire i fattori gene di interesse 9. Modelli animali di sclerosi laterale amiotrofica e SCI sia possibile modellare molti aspetti clinicamente rilevanti di queste malattie, tra cui la perdita frenico neurone motore e la conseguente compromissione respiratoria 10,11. Al fine di valutare l&#39;efficacia della NPC strategie basate sulla funzione respiratoria in questi modelli animali di sclerosi laterale amiotrofica e SCI, interventi cellulare deve essere specificamente indirizzato alle regioni contenenti terapeuticamente obiettivi importanti come i neuroni motori frenico. Forniamo un protocollo dettagliato per il multi-segmentale, il trapianto intraspinale di NPC nel midollo spinale cervicale materia grigia ventrale dei modelli neurodegenerative come topi G93A SOD1 e ratti, così come i ratti con lesione spinale e topi 11.
