Existensen av MSCs i synovialvätska är ett alternativ för cell-baserad terapi. Tidigare studier har visat att skada platser innehåller högre mängder av mesenkymala stamceller i deras synovial vätska, vilket kan vara positivt korrelerade med efter skada perioden5. MSCs i ledvätska kan vara fördelaktigt att vävnad för att förbättra den spontan läkning efter en skada18,19. Klinisk tillämpning av SF-MSCs täckts sällan i litter...

MSCs har föreslagits som en värdefull källa för regenerativ medicin, särskilt för brosk lesioner. MSCs, inklusive kondrocyter, osteoblaster, adipocyter, skelett myocyter och viscerala stromaceller, expandera i stort sett områdena för stamcellstransplantation på grund av deras höga expansion ränta och flera härstamning differentiering potentiella1. MSCs kan isoleras från Skelett muskel, synovialvätskan, benmärg och fettvävnad2,3,4. Resultaten har också bekräftar förekomsten av MSCs i ledvätska och tidigare forskning har identifierat synovial vätska-derived MSCs (SF-MSCs) som lovande kandidater för artikulära regenerering5,6.
Forskning och prekliniska experiment på mänskliga prover omfattas emellertid många etiska frågor. I stället kaniner har varit och fortsätter att vara den vanligaste djurarter för att demonstrera att transplantation av MSCs kan reparera broskskador. Under senare år ett ökande antal forskare har studerat kanin mesenkymala stamceller (rbMSCs) båda in vitro- och in-vivo, som dessa celler liknar mänskliga MSCs i deras cellulära biologi och vävnad fysiologi. Likaså klarar rbMSCs av att följa plastytor, visar spindel-fibroblast morfologi som mänskliga MSCs. Dessutom är kanin mesenkymala prover enkel och lätt att få7. Dessutom är de viktigaste punkterna att rbMSCs uttrycker yta markörer, såsom CD44, CD90 och CD105, och att flera härstamning differentieringen potentiella bevaras, som är överens med kriterierna för identifiering av MSC populationer som definieras av den internationella föreningen för cellterapi8,9. I synnerhet klarar synovial vätska chondroprogenitors av icke-hypertrofisk kondrogenes när induceras av TGF-β1, vilket gör dem lämpliga cell källor för fenotypiskt ledbrosk regenerering10,11, 12.
Isolering av SF-MSCs skiljer sig dock kraftigt från andra vävnader, inklusive navelsträngen, fettvävnad, perifert blod och benmärg. För närvarande är de vanligaste metoderna för rening och sortering av SF-MSCs flödescytometri och immunmagnetisk pärla-baserade sortering, även om metoden flöde flödescytometri kräver en specifik miljö och mycket dyra instrument13.
Denna artikel presenterar en procedur för enkel och minimalt invasiv insamling av prover av ledvätska från Nya Zeeland vita kaniner. Under förfarandet, de rbSF-MSCs är stabilt expanderade in vitro- och sedan isoleras med CD90 positiv magnetisk pärla-baserade förfaranden. Slutligen visar protokollet skaffa MSCs med hög renhet och livskraft från skördade cell källor.
I detta protokoll kännetecknas de isolerade rbSF-MSCs baserat på deras morfologi, uttryck för specifika markörer och pluripotenta stamceller. Flöde flödescytometri-baserade immunophenotyping avslöjar ett betydande positivt uttryck för CD44 och CD105, uttryck för CD45 och CD34 är negativa. Slutligen visar in vitro- test för rbSF-MSCs osteogent, adipogena och chondrogenic differentiering av dessa celler.

magnetic-activated cell sorting strategies to isolate and purify synovial fluid-derived mesenchymal stem cells from a rabbit model

Mesenkymala stamceller (MSC) är den största cell källan för cell-baserad behandling. MSCs från artikulära hålighet ledvätska kan potentiellt användas för brosk vävnadsteknik. MSCs från ledvätska (SF-MSCs) har ansetts vara lovande kandidater för artikulära regenerering och deras potentiella terapeutiska fördelar har gjort dem ett viktigt forskningsområde för sent. SF-MSCs från knä hålighet i Nya Zeeland vit kanin kan vara anställd som en optimerad translationell modell att bedöma människors regenerativ medicin. Med hjälp av CD90-baserade magnetiska aktiverad cell sortering (Mac) teknik, detta protokoll erhåller framgångsrikt kanin SF-MSCs (rbSF-MSCs) från denna kanin modell och ytterligare visar fullt MSC fenotypen av dessa celler genom att förmå dem att differentiera till osteoblaster, adipocyter och kondrocyter. Därför kan detta tillvägagångssätt tillämpas i den cellbiologiska forskningen och tissue engineering använder enkel utrustning och förfaranden.

Isolering, rening och kultur av de rbSF-MSCs: Detta protokoll använder Mac-datorer för att isolera rbSF-MSCs, baserat på uttrycket av MSC surface marker CD90. Ett processflödesdiagram rbSF-MSCs' isolering, rening, och karakterisering och protokollet i vitro kultur visas i figur 1.
