Description: Watch this Scientific Journal Video about Intrasplenic Transplantation of Hepatocytes After Partial Hepatectomy in NOD.SCID Mice at JoVE.com

Dette arbeidet ble støttet av kjernen bevilgning mottatt fra Department of bioteknologi, Indias regjering til de nasjonale Institutt for immunologi, New Delhi. Dr. Bhattacharjees nåværende adresse er delingen av gastroenterologi, Hepatology og ernæring, Children's Hospital i Los Angeles.

Fremgangsmåtene i denne protokollen er godkjent av den institusjonelle dyr etikk av det nasjonale Institutt for immunologi, New Delhi. Seriell referansenummeret for godkjenning er IAEC #319/13.
Merk: Det er gode ressurser på allmenn kirurgi prosedyrer20 og bestemte protokoller for gnager kirurgi21. For de gjør dyr kirurgi for første gang, er det anbefalt å mye praksis kirurgiske prosedyrer på dummies før på dyr.

Delvis hepatectomy er en etablert teknikk for undersøke leveren gjenfødelse, og overdreven hepatectomy rapporteres å etterligne AHF modellen. Blant dyr modeller av AHF er gnagere, spesielt mus, mest undersøkte modellen. For å få en leverskade modell i mus, til en 70% hepatectomy har blitt rapportert med en god survival rate25,26. Men i naken og andre immunodeficient mus, en 70% hepatectomy ble rapportert som fatale og dyr døde innen 24 timer<sup class="xre...

Foreløpig er hepatocyte transplantasjon foreslått som et alternativ til hele organtransplantasjon for behandling av pasienter med alvorlig lever lidelser. Det antas at det kan bygge bro pasienter til hele organ transplantasjon1. I tillegg til allogenic hepatocytter2, blir xenogenic hepatocytter3 og hepatocytter avledet fra stamceller4 også undersøkt i dyremodeller. I denne sammenheng, homing og engraftment er potensialet transplantert cellene i mottakeren et viktig kriterium for cellen basert terapi i akutt hepatic fiasko (AHF).
For å undersøke transplantasjon av hepatocytter eller hepatocyte-lignende celler5, opprettes AHF i en dyremodell kirurgisk6 eller farmakologiske7 prosedyrer, etterfulgt av transplanting celler. Å lage en AHF dyr modell av farmakologiske reagenser, mange hepatotoxins som d-galactosamine8, Paracetamol9, carbon tetrachloride10, thioacetamide11, Concanavalin A12, lipopolysakkarid13 , osv., har blitt brukt. Hver reagens genererer et unikt sett med funksjoner for AHF fra denne listen, men dessverre ikke enkelt reagens etterligner den menneskelige AHF. Videre AHF indusert av hepatotoxins tar lang tid, som setter dyr kronisk stress, og reproduserbar resultatene er vanskelig å få.
På den annen side, kirurgiske prosedyren for delvis hepatectomy (PHx) er ferdighet avhengige, og reproduserbar resultatene er lett å få etter å utvikle nødvendige ferdigheter. For å indusere AHF av kirurgiske inngrep alene, er fjerning av mer enn 70% av leveren påkrevd. men transplantert mindre enn en 70% hepatectomy kan fortsatt brukes til å studere engraftment og spredning av celler i leveren for å analysere deres terapeutiske kapasitet under leverskader14. Transplantasjon av hepatocytter har vært utført innlegg hepatectomy gjennom peritoneum15, hale blodåre16, hepatic blodåre17eller milt18. Foreløpig er hepatic blodåre-infusjon og intrasplenic transplantasjon av hepatocytter den foretrukne prosedyrer, fordi de er lettere å reprodusere.
I dette papiret, har vi beskrevet en prosedyre for en 30% delvis hepatectomy i NIKK. SCID (NIKKER. CB17-Prkdcscid/J) mus som den venstre flik av leveren er forbrukeravgift. Det er etterfulgt av transplantasjon 0,2 millioner GFP uttrykke mus (C57BL/6-vs (UBC-GFP) 30Scha/J) hepatocytter samt menneskelige opprinnelse NeoHep19 i milten. Denne fremgangsmåten fører til engraftment av transplantert cellene i leveren. Denne fremgangsmåten er de minst invasive og en minimal smertefulle teknikk.

intrasplenic transplantation of hepatocytes after partial hepatectomy in nod.scid mice

Delvis hepatectomy er en allsidig og reproduserbar metode lever foryngelse og effekten av cellen basert legemiddelselskap i ulike patologiske forhold. Delvis hepatectomy forenkler også økt engraftment og spredning av transplantert celler ved akselererende neovascularization og celle migrasjon mot leveren. Her beskriver vi en enkel protokoll for utføre 30% hepatectomy og transplantasjon av celler i milten av en ikke-obese diabetiker/alvorlig kombinert immunodeficient hilsen. SCID (NIKKER. CB17-Prkdcscid/j) musen.
I denne prosedyren er to små snitt gjort. Den første snittet er å avsløre og resect den venstre flik av leveren, og en annen liten snitt lages for å avsløre milten for intrasplenic transplantasjon av celler. Denne prosedyren krever ikke noen spesialisert kirurgiske ferdigheter, og det kan være ferdig i 5-7 minutter med mindre stress og smerte, raskere restitusjon og bedre overlevelse. Vi har vist transplantasjon av hepatocytter isolert fra en grønn fluorescerende protein (GFP) uttrykker mus (transgene C57BL/6-vs (UBC-GFP) 30Scha/J), samt hepatocyte som celler av menneskets opprinnelse (NeoHep) i delvis hepatectomized hilsen. SCID mus.

Hepatocyte spredning etter 30% delvis hepatectomy: Spredning av hepatocytter som de resterende lever etter 30% hepatectomy ble undersøkt av immunohistochemical (IHC) flekker for en celle spredning markør, Ki-67. Dag innlegget hepatectomy, mus var euthanized, gjenværende leveren lobes ble fjernet og parafinsnitt ble innhentet. Delene var farget med Ki-67 antistoff, etterfulgt av merking med pepperrot peroxidase (HRP) konjugert sekundære antistoff. Di-Amino Benzidine (DAB) ble brukt som underlag for HR...
