Forberedelse af plade Brugen af glasovertræk i 6-, 12- eller 48-brønds kulturplader til immunfluorescerende eller calciumbilleddannelseseksperimenter er en økonomisk og prøvebesparende operation. Celler vokser godt i plader uden coverlips under forberedelsen af primære cellekulturer. Derfor kan coverslips dispenseres i eksperimenter, såsom vestlig blot eller polymerase kædereaktion. Desuden er belægning et nødvendigt skridt, før plating celler, med eller uden coverslips. Laminin og poly-D-ly...

Den nederste urinvej har to hovedfunktioner: periodisk urinopbevaring og micturition1. Det nederste urinvejsnervesystem (LUTNS) styrer disse funktioner og er delikat og modtagelig for mange neuropatier, som kan medfødte (porfyri), erhvervet (Lyme sygdom), sekundær til sygdomstilstande (diabetisk cystopati), narkotika induceret (hæmoragisk blærebetændelse), kirurgi forårsaget (abdominoperineal resektion), eller skade forårsaget (traumatisk rygmarvsskade)2,3,4 ,5,6,7. I fysiologiske/patologiske undersøgelser er in vivo- og in vitro-forsøg lige så vigtige. Mens in vivo forskning på LUTNS er blevet udført på organ-, cellulære og molekylære niveauer i nogen tid, in vitro forskning på primære neuroner fra urinblæren er næsten ikke-eksisterende8,9. Selv om denne undersøgelse er begrænset, håber vi at være banebrydende for forskning på dette område, så andre forskere kan forbedre den. På denne måde kan denne co-kultur føre til en cellulær forståelse af fysiologisk dysfunktion i fænotyper, såsom blære neuron dysfunktion.
I modsætning til enteriske muskler med en klar retningsbestemthed af muskelcellerne i diskrete lag er blæremusklerne uorganiserede10. Derfor foreslår denne metode i stedet for at skrælle blærens ydre lag at fordøje hele blæren for at reducere driftsbesværet og forkorte forbehandlingstiden for en høj celleoverlevelsesrate.
Efter denne metode kan vi opnå en blandet kultur af neuroner og andre celler. De andre celler er uundværlige, fordi deres tilstedeværelse efterligner et in vivo-miljø11. Derudover giver sådanne celler de stoffer, der ikke er tilgængelige i mediet.
Denne metode involverer to trin til fordøjelsen. For det første, kollagen type II bruges til at hydrolysere kollagen, efterfulgt af trypsin, at adskille vævet icellerne 10. På denne måde spredes blærevæv i enkelte celler og vokser derefter relativt uafhængigt. Når neuronernes kultur modnes, kan neuronerne bruges til billeddannelse eller funktionelle assays.

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

Den nederste urinvej har to hovedfunktioner, nemlig periodisk urinopbevaring og micturition; disse funktioner formidles gennem central og perifer neuroregulering. Selvom der er udført omfattende forskning i det nedre urinvejsnervesystem, har de fleste undersøgelser fokuseret på primær kultur. Denne protokol introducerer en metode til isolation og kultur af blæreneuroner og glia fra Sprague-Dawley rotter. I denne metode blev neuronerne og gliaerne inkuberet i en 37 °C, 5% CO2 inkubator i 5-7 dage. Som følge heraf voksede de til modne former, der var egnede til relaterede efterfølgende immunfluorescenseksperimenter. Celler blev morfologisk observeret ved hjælp af et optisk mikroskop. Neuroner, synaptiske vesikler og glia blev identificeret ved henholdsvis β-III-tubulin og MAP-2, Synapsin-1 og GFAP-farvning. I mellemtiden blev immunokytokemi udført på flere neurotransmitter-relaterede proteiner, såsom cholin acetyltransferase, DYNLL2 og SLC17A9.

I processen med primær cellekultur var de erhvervede celler runde med lyse og klare grænser før den tilknyttede tilstand. Som neuroner voksede, dendritter og axoner begyndte at være forskellige. Efter 5-7 dages kultur nåede neuronerne en moden form med lange fremskrivninger, som var ideelle til billeddannelse eller funktionsstudier. Selv om de fleste urenheder og cellerester kunne fjernes på grund af skiftende medier, var visse rester knyttet til poly-D-lysin og lamininbelægning synlige (Figur...
