Kliniske, endoskopisk, radiologiske og histologiske evalueringer demonstrert effektiviteten av endoskopisk ADSC ført til esophageal striktur forebygging etter lengre ESD.

Ledelsen av overfladiske esophageal svulster har endret seg med utviklingen av nye endoskopiske teknikker. I dag er endoskopisk reseksjon førstelinjebehandling. Faktisk er det forbundet med lavere sykelighet og dødelighet enn en operasjon med like onkologiske resultater 1, 2, 3. Endoskopisk mucosal reseksjon (EPJ) og endoskopisk submucosal reseksjon (ESD) er de mest brukte teknikker. I tilfelle av en utvidet overfladisk tumor, blir ESD foretrukket. Sammenlignet med EMR, lar ESD en blokk resectioning, uavhengig av lesjon størrelse og form 4, 5, 6. Hoved forsinket komplikasjon av ESD er esophageal strikturdannelse, som vanligvis oppstår mellom en og to uker etter reseksjon. Siste publiserte studier har vist at strikturdannelse er korrelert tilStørrelsen på reseksjon. Den japanske Endoskopisk Society anbefaler å unngå ESD størrelser større enn ¾ av esophageal omkrets fordi de er forbundet med striktur utvikling i mer enn 90% av tilfellene, og er ansvarlig for alvorlige fôring problemer og betydelig forverring i livskvalitet. Forebygging av esophageal striktur fortsatt utfordrende. Mekanismer involvert i strikturdannelse er bare delvis kjent. Stricture formasjoner synes å resultere fra foreningen av to ulike mekanismer: (1) pro-inflammatorisk celle rekruttering og (2) overdreven fibrose utvikling 7. Flere forebyggende behandlinger har blitt foreslått. Resultatene var imidlertid ikke tilfredsstillende, med liten fordel og alvorlige bivirkninger 8, 9. Nylig, en japansk team, Ohki et al. Foreslått å transplantere en enkelt-lags cellefolien av autologe orale slimhinneceller inn i esophageal arret. Transplantasjon ble utført umiddelbart etter at ESD-10, 11. De demonstrerte effektiviteten av denne innovative tilnærming, først i en hundemodell og deretter i pasienter. Adipose tissue-deriverte stromale celler (ADSCs) er lovende i regenerativ medisin. Deres anvendelse på flere områder har vist interessante resultater, særlig i det sårhelende prosess. ADSC terapi gir flere fordeler, fordi cellene er lett isoleres og er forbundet med anti-inflammatoriske egenskaper, lokale immunmodulerende effekter, neovaskularisering induksjon og differensiering evner til mesenchymale og ikke-mesenchymale linjene 12, 13, 14. I en tidligere studie, vårt team demonstrerte effektiviteten til dobbel ADSC ark endoskopisk transplantasjon for esophageal striktur prevention etter lang ESD i en svine modell 15. I denne artikkelen er rapporter om ADSC ark konstruksjon og endoskopisk transplantasjon teknikk presenteres.

adsc-sheet transplantation to prevent stricture after extended esophageal endoscopic submucosal dissection

I tidligere år har celle-ark konstruere ansporet bred interesse i regenerativ medisin, spesielt for rekonstruktiv kirurgi prosedyrer. Utviklingen av diversifiserte teknologi som kombinerer adipose tissue-deriverte stromale celler (ADSCs) med ulike biomaterialer har ført til bygging av mange typer vev-konstruert substitutter, slik som bein, brusk, og fettvev fra gnagere, svin, eller menneskelige ADSCs. Utvidet esophageal endoskopisk submucosal disseksjon (ESD) er ansvarlig for esophageal strikturdannelse. Innsnevringen forebygging er fortsatt utfordrende, med ingen effektive behandlinger tilgjengelig. Tidligere studier har vist effektiviteten av mucosal celle-ark transplantasjon i en hundemodell og hos mennesker. ADSCs er tilskrevet anti-inflammatorisk egenskaper, lokale immunstimulerende effekter, neovascularization induksjon og differensiering evner til mesenchymale og ikke-mesenchymale linjene. Denne originale studien beskriver endoskopisk transplantation av en ADSC vev-konstruert konstruksjon for å hindre esophageal striktur i et svine modell. Den ADSC konstruksjonen ble sammensatt av to allogenic ADSC ark lagvis på hverandre på en papirstøtten membran. De ADSCs ble merket med PKH67 fluorophore å tillate probe-baserte confocal laser endomicroscopy (pCLE) overvåking. På dagen for transplantasjon, ble en 5-cm og hemi-omkrets ESD kjent for å indusere esophageal innsnevring utført. Dyrene ble umiddelbart endoskopisk transplantert med 4 ADSC konstruksjoner. Den fullstendige adhesjon av ADSC konstruksjonene ble oppnådd etter 10 min med forsiktig søknad. Dyrene ble avlivet på dag 28. Alle dyrene ble med hell transplantert. Transplantasjon ble bekreftet på dag 3 med en positiv pCLE evaluering. Sammenlignet med transplanterte dyr, kontrolldyrene utviklet alvorlige strikturer, med stor utvikling fibrotisk vev, hyppigere fordøyelses trøbbel, og redusert vektøkning. I vår modell transplantasjon av allogenic ADSCs, organisert i doble celle ark, etter lengre ESD var vellykket og sterkt assosiert med en lavere esophageal striktur rate.

Kulturen i ADSCs og fremgangsmåten for å oppnå den ADSC plate er vist i figur 1. Figur 2 viser konstruksjonen av graftet, sammensatt av to ADSC ark lagvis på hverandre på sin papirbærermembran. ADSCs tidligere merket med PKH67 fluoroforen å tillate in vivo pode overvåking med pCLE. Figur 3 viser de forskjellige trinnene i utvidet esophageal endoskopisk submucosal disseksjon, noe som resulterer i en 5-cm og hemi-omkrets e...
