Under pancreasudviklingen er differentierende pancreasceller i umiddelbar nærhed af endotelceller fra aorta, endvidere pancreasøer er tæt vaskulariseret at fremme en hurtig udveksling af blodglucose og ø-hormoner. I betragtning af disse fakta, er det ikke overraskende, at endotelceller spiller en vigtig rolle i processen med pancreas organogenese. Medens betydningen af endotelceller under pancreasudviklingen stigende grad værdsat, er dens rolle i in vitro differentiering af embryoniske celler mindre unders...

endothelial cell co-culture mediates maturation of human embryonic stem cell to pancreatic insulin producing cells in a directed differentiation approach

Embryonale stamceller (ESC) har to egenskaber: de kan være uendeligt opformeres in vitro i en udifferentieret tilstand, og de ​​er pluripotente og har således potentialet til at differentiere til flere slægter. Sådanne egenskaber gør ESC særdeles attraktiv for celle-baseret terapi og regenererende behandling ansoegninger 1. Men for sit fulde potentiale skal realiseres cellerne skal differentieres til modne og funktionelle fænotyper, hvilket er en skræmmende opgave. En lovende fremgangsmåde til induktion af cellulær differentiering er nøje efterligner bane organogenese i in vitro indstilling. Pancreasudviklingen vides at forekomme i bestemte trin 2, startende med endoderm, som kan udvikle sig til adskillige organer, herunder lever og pancreas. Endoderm induktion kan opnås ved modulation af nodal vej gennem tilsætning af activin A 3 i kombination med adskillige vækstfaktorer 4-7 </sup&gt;. Endelige endoderm celler underkastes derefter pancreas engagement inhibering af sonisk pindsvin inhibering, som kan opnås in vitro ved tilsætning af cyclopamine 8. Pancreas modning medieres af adskillige parallelle arrangementer, herunder inhibering af indskæringen signaler aggregering af pancreas progenitorer i 3-dimensionelle klynger, induktion af vaskularisering, for at nævne nogle få. Langt den mest succesfulde in vitro modning af ØSU afledte pancreasstamfaderceller, er blevet opnået gennem hæmning af hak signalering af DAPT tilskud 9. Selv succes. Resulterer i et lavt udbytte af det modne fænotype med nedsat funktionalitet En mindre undersøgte område er virkningen af endotelcelle signalering i pancreas modning, hvilket i stigende grad værdsat som en vigtig bidragende faktor i in vivo pancreasø modning 10,11. Den aktuelle undersøgelse udforskes sådan virkning af endothelIAL celle-signalering i modning af humane ESC afledte pancreasstamfaderceller i insulinproducerende ø-lignende celler. Vi rapporterer en flertrins rettet differentiering protokol, hvor de humane ESC først induceres mod endoderm af activin A sammen med inhibering af PI3K pathway. Pankreatisk specifikation endoderm celler opnås ved inhibering af sonisk hedgehog signalering ved Cyclopamine sammen med retinoid induktion ved tilsætning af retinsyre. Den endelige modning induceres af endotelcelle signalering opnås ved en co-kultur konfiguration. Mens flere endotelceller er blevet testet i co-kultur, heri præsenterer vi vores data med rotte hjerte mikrovaskulære endotelceller (RHMVEC), primært for at lette analysen.
