Denna nya isolering och expansion metod är en enkel och effektiv process som är mer effektiv och mindre tidskrävande genom att undvika någon cell separation (ingen densitetsgradient behövs) och billigare än konventionella tekniker. Genom att använda pHPL kontakt med nötkreatur antigener och möjliga efterföljande xenoimmunization är utesluten. Under kultur perioden små blodproppar kan bildas, som orsakas av pHPL. Baserat på våra erfarenheter av dessa blodproppar påverkar inte koloni bildning och celltillv?...

isolation and large scale expansion of adult human endothelial colony forming progenitor cells

Denna uppsats presenterar en ny återhämtning strategi för endotelceller kolonibildande progenitorceller (ECFCs) från hepariniserat men annars unmanipulated vuxna humant perifert blod inom ett medelvärde på 12 dagar. Efter storskaliga utbyggnaden&gt; 1x10 8 ECFCs kan erhållas för ytterligare tester. Fördel genom att använda pHPL kontakten av mänskliga celler med bovint serum antigener kan uteslutas. Med flödescytometri och immunhistokemi de isolerade cellerna kan karakteriseras som ECFC och in vitro-funktionalitet för att bilda blodkärl liknande strukturer som kan testas i ett matrigel analys. Ytterligare dessa celler kan subkutant injicerat i en musmodell för att bilda funktionella, perfusion fartyg in vivo. Efter långsiktiga expansion och frysförvaring spridning, funktion och genomisk stabilitet verkar vara bevaras. 3,4 Detta djur-protein utan isolering och expansion metod är lätt att tillämpa för att generera en stor mängd ECFCs.
