Preparazione piastra L'uso di coverlips in vetro in piastre di coltura da 6, 12 o 48 pozzi per esperimenti di imaging immunofluorescente o di calcio è un'operazione economica e parsimonioso. Le cellule crescono bene in piastre senza coverlips durante la preparazione di colture cellulari primarie. Pertanto, le coverlips sono dispensabili in esperimenti, come la macchia occidentale o la reazione a catena della polimerasi. Inoltre, il rivestimento è un passo necessario prima di placcare le celle, con o...

Il tratto urinario inferiore ha due funzioni principali: conservazione periodica delle urine e micturizione1. Il sistema nervoso del tratto urinario inferiore (LUTNS) controlla queste funzioni ed è delicato e suscettibile a molte neuropatie, che possono essere innate (porfiria), acquisite (malattia di Lyme), secondarie agli stati di malattia (cistopatia diabetica), indotte da farmaci (cistite emorragica), chirurgia causata (resezione addominoperineale) o lesioni causate (lesione traumatica del midollo spinale)2,3,4,5,6,7. Negli studi fisiologici/patologici, gli esperimenti in vivo e in vitro sono ugualmente importanti. Mentre la ricerca in vivo sull'LUTNS è stata condotta a livello di organo, cellulare e molecolare per qualche tempo, la ricerca in vitro sui neuroni primari della vescica urinaria è quasi inesistente8,9. Sebbene il presente studio sia limitato, speriamo di essere pionieri della ricerca in questo settore in modo che altri ricercatori possano migliorarla. In questo modo, questa co-coltura può portare a una comprensione cellulare della disfunzione fisiologica nei fenotipi, come la disfunzione neuronale della vescica.
A differenza dei muscoli enterici con una chiara direzionalità delle cellule muscolari in strati discreti, i muscoli della vescica sono disorganizzati10. Pertanto, invece di staccare lo strato esterno della vescica, questo metodo propone di digerire l'intera vescica per ridurre la difficoltà di funzionamento e abbreviare i tempi di pre-elaborazione per un alto tasso di sopravvivenza cellulare.
Seguendo questo metodo, possiamo ottenere una coltura mista di neuroni e altre cellule. Le altre cellule sono indispensabili perché la loro presenza imita un ambiente in vivo11. Inoltre, tali cellule forniscono le sostanze che non sono disponibili nel mezzo.
Questo metodo prevede due passaggi per la digestione. In primo luogo, la collagenasi di tipo II viene utilizzata per idrolizzare il collagene, seguita dalla tripparina, per dissociare il tessuto nelle cellule10. In questo modo, i tessuti della vescica vengono dispersi in singole cellule e quindi crescono relativamente indipendenti. Quando la coltura dei neuroni matura, i neuroni possono essere utilizzati per l'imaging o test funzionali.

isolation and culture of primary neurons and glia from adult rat urinary bladder

Il tratto urinario inferiore ha due funzioni principali, vale a dire la conservazione periodica delle urine e la micturizione; queste funzioni sono mediate attraverso la neuroregolazione centrale e periferica. Sebbene sia stata condotta un'ampia ricerca sul sistema nervoso del tratto urinario inferiore, la maggior parte degli studi si è concentrata sulla cultura primaria. Questo protocollo introduce un metodo per l'isolamento e la coltura dei neuroni vescicali e degli glia dei ratti Sprague-Dawley. In questo metodo, i neuroni e glia sono stati incubati in un incubatore di 37 °C, 5% CO2 per 5-7 giorni. Di conseguenza, sono cresciuti in forme mature adatte ai successivi esperimenti di immunofluorescenza correlati. Le cellule sono state osservate morfologicamente usando un microscopio ottico. Neuroni, vescicole sinaptiche e glia sono stati identificati rispettivamente da β-III-tubulina e MAP-2, Synapsin-1 e GFAP. Nel frattempo, l'immunocitochimica è stata eseguita su diverse proteine correlate al neurotrasmettitore, come la colina acetiltransferasi, DYNLL2 e SLC17A9.

Nel processo di coltura cellulare primaria, le cellule acquisite erano rotonde con limiti luminosi e chiari prima dello stato attaccato. Man mano che i neuroni crescevano, dendriti e assoni cominciavano ad essere distinti. Dopo 5-7 giorni di coltura, i neuroni hanno raggiunto una forma matura con proiezioni lunghe, ideali per l'imaging o gli studi di funzione. Sebbene la maggior parte delle impurità e dei detriti cellulari potessero essere rimossi a causa del cambiamento dei mezzi, alcuni residui attaccati al rivestimen...
