Mål baserat läkemedelsutveckling, där små molekyler identifieras som påverkar aktiviteten av ett specifikt protein, har varit fokus i många befintliga screening insatser. Även om detta tillvägagångssätt har lämnat många läkemedel, skärmar baserat på att vända en fenotyp, klassiskt farmakologi, har varit mer framgångsrika i att identifiera först-i-klass föreningar som varit kliniskt effektiva1. En nackdel till fenotypiska läkemedelsutveckling är att det är beroende av tillgån...

Framgång i att identifiera läkemedel som kan användas för att rikta en sällsynt sjukdom är beroende av utvecklingen av testmetoder som kan användas för screening. Hypotesen eller mål-baserade skärmar (omvänd farmakologi) är användbara, men kräver en detaljerad förståelse av den molekylära basen för sjukdomen. Fenotypiska skärmar (klassiskt farmakologi) undvika behovet av en detaljerad förståelse av biokemiska vägar, men i stället förlita sig på att utveckla modeller som exakt speglar patofysiologin bakom sjukdomen. Trots entusiasmen för mål-baserade metoder avslöja analyser av FDA-godkända först-i-klass läkemedel att fenotypiska skärmar har varit långt mer framgångsrik1. Det övergripande målet med denna metod är att inrätta en plattform för high throughput screening som kan användas för att identifiera små molekyler för behandling av metabola leversjukdom. Flera in vitro- modeller har beskrivits inklusive primära hepatocyter, hepatom celler och levern progenitor celler2. Men de flesta av dessa modeller har begränsningar och det finns ett behov för nya modeller som exakt kan sammanfatta patofysiologin av metabolisk lever brister i kultur. Nyligen, mänskliga pluripotenta stamceller kombinerat med gen editering har erbjudit en möjlighet att modellera även den mest sällsynta av sällsynta sjukdomar i kultur utan att behöva tillgång patienter direkt3. Medan användningen av patientspecifika iPSCs som ett verktyg att upptäcka små molekyler för behandling av sällsynta leversjukdomar är begreppsmässigt rimliga, finns det endast ett fåtal rapporter demonstrera genomförbarheten av denna metod4. Vi har dock nyligen etablerat en plattform som används för iPSC-derived hepatocyter att framgångsrikt identifiera läkemedel som kan vara repurposed för behandling av brister i metabolism i levern5.
Detta protokoll förklarar processen att skilja mänskliga iPSCs hepatocyte-liknande celler i 96 brunnar och använda dem för att skärmen ett bibliotek av små molekyler. Här beskrivs också endpoint analysen med hyperkolesterolemi som exempel metabolisk leversjukdom. Denna strategi bör vara användbart att studera roll och tillämpning av små molekyler i samband med smittsam leversjukdom, metabolisk leversjukdom, drug toxicitet och andra leversjukdomar.

using human induced pluripotent stem cell-derived hepatocyte-like cells for drug discovery

Förmågan att skilja mänskliga inducerade pluripotenta stamceller (iPSCs) till hepatocyte-liknande celler (HLCs) ger nya möjligheter att studera medfödda rubbningar i levermetabolism. Förfarandet kräver dock för att tillhandahålla en plattform som stöder identifiering av små molekyler som kan användas för att behandla leversjukdom, en kultur-format som är kompatibelt med screening tusentals föreningar. Här beskriver vi ett protokoll som använder helt definierade kultur förhållanden, att reproducerbara differentiering av mänskliga iPSCs hepatocyte-liknande celler i 96 brunnar vävnadsodling plattor. Vi ger också ett exempel på att använda plattformen för att skärmen föreningar för sin förmåga till lägre Apolipoprotein B (APOB) produceras från iPSC-derived hepatocyter som genereras från en familjär hyperkolesterolemi patient. Tillgången till en plattform som är kompatibel med läkemedelsutveckling bör göra det möjligt för forskare att identifiera nya behandlingar för sjukdomar som påverkar levern.

Generation av hepatocyte - som celler: Figur 1 beskriver tidsramen för de förändringar som sker under differentieringen av mänskliga iPSCs hepatocyte-liknande celler. Kulturen av iPSCs på E-Cad-Fc ger cirka 2 mm diameter kolonier som express pluripotenta markören OCT4 (figur 1A-B). Morfologi av celler odlas på en E-cadherin matris blir något annorlunda ti...

Using Human Induced Pluripotent Stem Cell-derived Hepatocyte-like Cells for Drug Discovery

Använder mänskliga inducerade pluripotenta stamceller-derived Hepatocyte-liknande celler för läkemedelsutveckling

Det protokoll som presenteras här beskriver en plattform för identifiering av små molekyler för behandling av leversjukdom. En stegvis beskrivning presenteras beskriver hur att skilja iPSCs till celler med hepatocyte egenskaper i 96 brunnar och använda cellerna till skärmen för små molekyler med potentiell terapeutisk aktivitet.
