Metoder brukt til ingeniør levende nyre vev konstruksjoner varierer med hensyn til både type celler og biologisk materiale benyttes, og i mange tilfeller er foreldet eller ikke godt karakterisert i litteratur7. Mens mange bruker stamcelleforskningen tilnærminger eller recapitulating enkeltkomponenter i nyre arkitekturen i isolasjon, er utsiktene til kunstig gjenskape et hele organ med over 26 forskjellige differensiert celletyper fra mobilnettet suspensjoner overveldende for å vurdere<sup clas...

Kronisk nyresykdom (Parallelt) er en av dagens store folkehelsen utfordringer verden1. Utbredelsen av Parallelt i USA er over 14% av befolkningen, med over 600 000 amerikanere lider av den strengeste formen, end-stage renal disease (ESRD)2. De gjeldende behandlingstilbud tilgjengelig for de med ESRD inkluderer dialyse og nyre transplantasjon. Selv om ca 25 000 pasienter gjennomgår nyre transplantasjon hvert år, legges et betydelig antall pasienter årlig fører til et stort misforhold mellom de venter en livreddende orgel og de mottaende transplantasjon3. I tillegg til sin alvorlige negative virkninger på lang levetid og livskvalitet er dialyse forbundet med en forbløffende økonomisk byrde. I 2014 vil summert Medicare betalt krav over $30 milliarder for ESRD pasienter2. Med en begrenset orgel forsyning og ingen tydelig downtrend i pasienter som krever dialyse, forskningsinnsats å identifisere alternative løsninger dialyse og transplantasjon er alltid viktig. Selv en relativt kort forsinkelse i behovet for dialyse øker pasientens antall kvalitet-justert liv år og produktiviteten betydelig samtidig utsette dialyse-relaterte kostnader4,5,6.
Løsninger for funksjonell vev tap, som med ESRD, er for tiden studert i tissue engineering og regenerativ medisin laboratorier, med variert tilnærminger mellom stillaset-baserte organoid fabrikasjon hele organ engineering bruker decellularized orgel strukturer for mobilnettet implantasjon,7,,8,,9,,10,,11. Recapitulating komplekse nyre strukturer fra marginal eller forkastet nyrer har bare delvis blitt undersøkt. Faktisk er nesten 20% av nyrer anskaffet for transplantasjon forkastet for ulike grunner12,13. Funksjonell nyre vev fra disse antatte grafts kan benyttes og innlemmet i én eller flere vev-konstruert konstruksjoner. Tidligere studier har vist muligheten for å arbeide med disse kasserte organer, utnytte nyrer for ekstra-mobile matrisen for tissue engineering formål14,15. Imidlertid har noen brukt primære nephronal vev fra friske nyrer vev-engineering formål16,17,18.
En metode beskrevet tidligere av Kim et al. innebærer isolering av nyre "deler" fra frisk rotte nyrene, som var så frø på polyglycolic syre (PGA) stillaser konstruere fabrikasjon16. Imidlertid lite informasjon er gitt om nøyaktig disseksjon metodikk og segmenter var oppnådd fra en kombinasjon av fine hakking og filtrering. Vi beskriver en endring av denne protokollen, som produserer tilsvarende atskilte nyre segmenter med intakt nephronal arkitektur, men stedet stoler på microdissection teknikker. Nephrectomies utføres på levende voksen mus, hvoretter nyrene overføres til disseksjon mikroskopet der nyre kapselen er fjernet, og vevet er ytterligere dissekert. Små-bar 30½ G nåler brukes som skjærende instrumenter og også som guider hjelpe i disseksjon, som nålen diameter er lik målet diameteren på nyre segmentene. Isolert, i dette tilfellet murine, nyre segmentene opprettholde levedyktighet i kultur og innlemme med stillaset-fri endothelial-fibroblast mobilnettet konstruksjoner19. Disse konstruerer har tidligere blitt brukt til ingeniør andre organer, inkludert en bio-kunstig bukspyttkjertelen20.

microdissection of primary renal tissue segments and incorporation with novel scaffold-free construct technology

Nyre transplantasjon er nå en mainstream terapi for end-stegs nyre sykdom. Men med ca 96 000 mennesker på venteliste og bare en fjerdedel av pasientene oppnå transplantasjon, er det en overmodent for alternativer for de med sviktende organer. For å redusere de skadelige konsekvensene dialyse sammen med totale helsetilbud koster det innebærer, pågår aktive etterforskningen på jakt etter alternative løsninger til organtransplantasjon. Implanterbare vev-konstruert nyre mobilnettet konstruksjoner er en slik mulig tilnærming å erstatte tapt nyre funksjonalitet. Her er beskrives for første gang, microdissection i murine nyrene for isolering av levende corticomedullary nyre segmenter. Disse segmentene er i stand til rask innlemmelse i stillaset-fri endothelial-fibroblast konstruksjoner som kan aktivere rask forbindelse med verten blodkar når implantert. Voksen mus nyrer ble anskaffet fra levende givere, etterfulgt av stereoscope microdissection å få nyre segmenter 200-300 µm i diameter. Flere nyre konstruksjoner ble laget ved hjelp av primære nyre segmenter høstet fra eneste nyre. Denne metoden viser en prosedyre som kunne berge funksjonelle nyre vev av organer som ellers ville bli forkastet.

Protokollen beskrevet produserer ca 50 nyre segmenter per pyramideformet 2 mm3 delen av nyre vev. Nyre segmentene som er behandlet og fotografert har rørformet og glomerular i ulike proporsjoner (se figur 2). Intakt segmentene ble utsatt for en analyse for å bestemme levedyktigheten til ulike segmenter gang hver 24 h i tre dager. Green-fluorescerende calcein-er finnes med intracellulære esterase aktivitet, indikativ av levende celler. Red-fluore...
