Description: Watch this Scientific Journal Video about Isolation of Endothelial Progenitor Cells from Human Umbilical Cord Blood at JoVE.com

Dette materiale er baseret på arbejde støttet af National Science Foundation under Grant nr. CMMI-1452943 og af University of Arkansas udmærkelse College. Vi vil også gerne anerkende Arkansas ledning blodbank for at forsyne os med ledningen blod enheder.

denne forskning blev udført med godkendelse af University of Arkansas institutionelle Review Board (godkendelsesnummer 16-04-722). Umbilical cord blood enheder blev indsamlet i citrat phosphat dextrose (CPD) løsning på Arkansas ledning blodbank, og enheder, der ikke opfyldte kravet om oplagring blev doneret til forskning. Ledning blod enheder blev leveret til laboratoriet inden for 24 timer af samling ved omgivelsestemperatur.

Som tidligere nævnt tilhænger EPCs besidder en cobblestone morfologi. Vores isolerede Middelhavstredjelandene skred fra en spindel-formet celle koloni (figur 2A-2D) i de tidlige stadier til en cobblestone koloni (figur 2E-2F) over en periode af ti dage i kultur. EPCs er blevet stemplet forskelligt af forskellige forskergrupper, nemlig som sent endotel stamfader celler10, endotel kolonidannende celler<su...

Flere forskere har studeret karakteristika og potentiale af menneskelige EPCs5,10,11,12,13. EPCs kan betegnes som cirkulerende celler, der har evnen til at overholde endotel væv i lokaliteter af hypoxi, iskæmi, skade eller tumordannelse og bidrage til dannelsen af nye vaskulære strukturer4,14. Deres observerede inddragelse i neovascularization, i form af postnatal vasculogenesis, har ført til en forståelse af Patofysiologi af disse celler og deres anvendelse i terapeutiske anvendelser4,15, 16. antallet af EPCs i individ har vist sig at være korreleret med hjerte-kar-patologi9,15,16,17,18,19 ,20. Andre undersøgelser har også opdelte EPCs ind i en ventil fibroblast-lignende fænotype og foreslået, at disse celler kan bruges til vævsmanipulering hjerte ventiler7,21.
Bestemt celle overflade molekyler nødvendigt at isolere EPCs er ikke blevet klart identificeret på grund af uoverensstemmelser mellem undersøgelser4. Vedhæftning af multinationale selskaber til en bestemt matrix, med udsættelse for en række dyrkningsbetingelser, er udført af flere grupper1,17,22,23, tyder på, at formodede EPCs kan vise forskellige fænotypiske egenskaber. Disse egenskaber omfatter manglende phagocytotic evne, tube dannelse i Matrigel og optagelsen af Dil-acetyleret low-density lipoprotein. Høj clonogenic og proliferativ potentiale er to egenskaber med hvilke EPCs kan være hierarchized5. EPCs kan også indgå i vitro tubuli når cocultured med menneskelige fosterets lunge fibroblaster4. Disse celler er kendt for at udtrykke endotel celle overflade markører og at dele nogle af hæmatopoietisk markører13,24,25. De positivt udtryk markører, der er bredt accepteret til fænotyper EPCs er CD31, CD34, vaskulær endotel vækstfaktor receptor 2 (VEGFR2), von Willebrands faktor (vWF), CD133, c-Kit, og vaskulære endotel cadherin (VE-cadherin)4 , 18. celler, der co express CD90, CD45, CD14, CD115 eller alpha-glat muskel aktin (α-SMA) ikke anses for at være EPCs på grund af deres begrænsede proliferativ potentielle, evne til at phagocytosis bakterier, og manglende evne til at danne de novo menneskelige fartøjer i vivo4,7. Denne artikel beskriver en modificeret protokol for isolation i endothelial stamceller fra menneskelige navlestrengsblod uden behov for enhver celle sortering protokoller. Til denne artikel brugt vi CD31, CD34 og VEGFR2 som de positive markører, med α-SMA som negativ indikator.
I denne artikel foreslår vi en metode til at isolere og dyrkning endotelceller stamceller fra navlestrengsblod uden celle sortering ved hjælp af specialiseret endotel vækstmediet suppleret med vækstfaktorer (EGM). Denne EGM indeholder vaskulær endotel vækstfaktor (VEGF) og fibroblast vækstfaktor (FGF), som forbedrer overlevelsen, spredning og migration af endothelceller26. Det omfatter også ascorbinsyre, som er ansvarlig for at vedligeholde den brostensbelagte morfologi af celler; insulin-lignende vækstfaktor-1 (IGF-1), som giver angiogene og vandrende funktion; og heparin, som medfører forbedret stabilitet på lang sigt af vækstfaktorer i de mellemstore26. Andre vækstfaktorer, tilføjes i endothelial cellekulturmedium omfatter tilskud med epidermal vækst faktor (EGF), som hjælper med at stimulere celleproliferation og differentiering og hydrocortison, som sensitizes celler til EGF26 . Vi viser, at brugen af denne særlige vækstmedium giver højere antal EPCs sammenlignet med endotel basal medium (EBM) eller Dulbeccos modificerede Eagle Medium (DMEM).

isolation of endothelial progenitor cells from human umbilical cord blood

Eksistens i endothelial stamceller (EPCs) i perifert blod og sit engagement i vasculogenesis blev først rapporteret af Ashara og kolleger1. Senere, dokumenteret andre eksistensen af lignende typer af EPCs stammer fra knoglemarven2,3. Mere nylig, Yoder og Ingram viste at EPCs stammer fra navlestrengsblod havde en højere proliferativ potentiale i forhold til dem isoleret fra voksen perifere blod4,5,6. Ud over at være involveret i postnatal vasculogenesis, har EPCs også vist lovende som en celle kilde til oprettelse af væv-manipuleret vaskulære og hjertet ventilen konstruktioner7,8. Forskellige isolation protokoller findes, hvoraf nogle omfatter celle sortering af mononukleære celler (multinationale selskaber), der stammer fra kilder nævnt tidligere ved hjælp af endotel og hæmatopoietisk markører, eller dyrkning af disse multinationale selskaber med specialiserede endotel vækst medium, eller en kombination af disse teknikker9. Her præsenterer vi en protokol til isolering og kultur af EPCs ved hjælp af specialiseret endotel medium suppleret med vækstfaktorer, uden brug af immunosorting, efterfulgt af en karakterisering af isolerede celler ved hjælp af Western blotting og immunfarvning.

Isolation og ekspansion i Endothelial stamceller: En skematisk (figur 1) er fastsat skildrer den samlede protokol. Forskellige blod komponent lag blev observeret efter tæthed gradient centrifugering af menneskelige navlestrengsblod med tæthed gradient medium. Ved såning multinationale selskaber på de kollagen-behandlede plader, blev udkommet af kolonier først observeret mellem dage 5 og 7 (fig. 2A...

Isolation of Endothelial Progenitor Cells from Human Umbilical Cord Blood

Målet med denne protokol er at isolere endotelceller stamceller fra navlestrengsblod. Nogle af applikationer omfatter brug af disse celler som en biomarkør for at identificere patienter med hjerte-kar-risiko, behandling af iskæmisk sygdomme, og at skabe væv-manipuleret vaskulære og hjertet ventilen konstruktioner.
