Injiserbare GH hydrogeler har stort potensial for in vivo applikasjoner på grunn av deres evne til å homogent innlemme ulike terapeutiske midler in situ. Videre kan deres fysiske og biokjemiske egenskaper enkelt manipuleres basert på sykdomsavhengige krav. I denne forbindelse har injiserbare hydrogeler blitt foreslått for å løse de viktigste begrensningene i gjeldende hjertestamcellebehandling hemmet av dårlig overlevelse og celleretensjon (det vil si < 10% innen 24 timer etter transplantasjon) i det skadede hjert...

Hjertestamcelleterapi har dukket opp som en potensiell tilnærming for hjerteinfarkt reparasjon og regenerering1,2. Til tross for de siste positive resultatene i dyremodeller og kliniske studier, er anvendelsen av stamcellebasert terapi for hjerteinfarkt reparasjon begrenset på grunn av lav oppbevaring og dårlig overlevelse av injiserte celler ved det infarcted hjertevev3,4. Som et resultat har bruk av cellebasert vevsteknikk, inkludert injiserbarebiomaterialer 5,hjertepatcher6og celleark7,blitt intensivt studert for å forbedre celleretensjon og integrering i verts myokardiet.
Blant de ulike potensielle tilnærmingene til bioingeniør hjertevev reparasjon, injiserbare hydrogeler kombinert med passende celletyper, for eksempel mesenchymal stamceller (MSCs), embryonale stamceller (ESCer), og indusert pluripotente stamceller (iPSCs), er et attraktivt alternativ for effektivt å levere celler i hjerteinfarktregioner 8,9. Gelatin, en velkjent naturlig polymer, kan brukes som en injiserbar matrise på grunn av sin store biokompatibilitet, betydelig biologisk nedbrytbarhet og redusert immunogenitet sammenlignet med et bredt spekter av biomaterialer som brukes i biomedisinske applikasjoner. Selv om gelatinbaserte injiserbare plattformer har stort potensial, forblir deres anvendelighet in vivo begrenset basert på deres lave mekaniske stivhet og enkel nedbrytbarhet i det fysiologiske miljøet.
For å overvinne disse begrensningene, har en roman og enkel design av gelatinbaserte hydrogeler bestående av hydroksyfenylpropionsyre blitt foreslått for in vivo-applikasjoner. Gelatin-hydroksyfenylpropionsyre (GH) konjugater kan kryss-koblet in situ i nærvær av et enzym, pepperrot peroxidase (HRP), og deretter innkapsle ulike legemidler, biomolekyler, eller celler i hydrogel, noe som tyder på stort potensial i vev engineering applikasjoner10,11,12,13,14. I tillegg har vi nylig undersøkt de terapeutiske effektene av GH hydrogels som inneholder innkapslede MSCer og demonstrert deres bruk i vellykket hjertereparasjon og regenerering etter MI i en murine modell15. I denne protokollen beskriver vi en enkel teknikk for innkapsling og in vitro tredimensjonal (3D) spredning av MSCer innen GH hydrogels. Vi introduserer også en kirurgisk prosedyre designet for å generere en murine MI-modell via koronarligation og intramyokarial transplantasjon av MSC-lasting GH hydrogels inn i det infarcted hjertet.

intramyocardial transplantation of msc-loading injectable hydrogels after myocardial infarction in a murine model

En av de store problemene overfor dagens hjerte stamcellebehandling for å forebygge postinfarkt hjertesvikt er lav retensjon og overlevelse av transplanterte celler i det skadede myokardiet, som begrenser deres terapeutiske effekt. Nylig har bruken av stillasbiomaterialer fått oppmerksomhet for å forbedre og maksimere stamcellebehandling. Målet med denne protokollen er å innføre en enkel og grei teknikk for å transplantere benmargsavledede mesenchymale stamceller (MSCer) ved hjelp av injiserbare hydroksyfenylpropionsyre (GH) hydrogeler; hydrogelene er gunstige som en celleleveringsplattform for hjertevevsteknikk på grunn av deres evne til å være krysskoblet in situ og høy biokompatibilitet. Vi presenterer en enkel metode for å fremstille MSC-lasting GH hydrogels (MSC / hydrogels) og evaluere deres overlevelse og spredning i tredimensjonal (3D) in vitro kultur. I tillegg demonstrerer vi en teknikk for intramyokarial transplantasjon av MSC/hydrogeler hos mus, som beskriver en kirurgisk prosedyre for å indusere hjerteinfarkt (MI) via venstre fremre synkende (LAD) koronar ligation og påfølgende MSC / hydrogels transplantasjon.

For effektivt å levere MSCer til det infarktede myokardiet, ble MSC-lasting in situ kryss-linkable hydrogeler beskrevet i figur 1 brukt i denne protokollen. Før in vivotransplantasjon ble spredning og overlevelse av MSCer i GH-hydrogeler bekreftet av en 3D in vitro live/dead cell staining analyse (live: grønn; død: rød). Som vist i figur 2viste representative bilder tilstrekkelig spredning av mscer, som viser forgrenede nettverk i GH-hydrogeler. I tillegg b...
