De generatie van uitgelijnde myocardiale weefsel is een belangrijke voorwaarde voor het aanpassen van de recente ontwikkelingen in de stamcel biologie om klinisch bruikbare doeleinden. Hierin beschrijven we een microcontact afdrukken benadering voor de nauwkeurige controle van cellulaire vorm en functie. Met behulp van zeer zuivere populaties van embryonale stamcellen afgeleid cardiale voorlopercellen, we dan het genereren van anisotrope functionele myocardium.

Generatie van Aligned Functionele myocardweefsel Door microcontact afdrukken

Dit manuscript beschrijft de creatie van gedefinieerde geëngineerde hartweefsels met behulp van uitdrukking van oppervlaktemarkers en celsortering. De gedefinieerde weefsels kunnen vervolgens worden gebruikt in een multi-weefsel bioreactor om mechanismen van hartceltherapie te onderzoeken om zo een functioneel, maar gecontroleerd, modelsysteem van het menselijk hart te bieden.

De bouw van Defined Human Engineered hartweefsel om te studeren Mechanismen van Cardiac Cell Therapy

Dit protocol beschrijft 3D bioprinting van hartweefsel zonder het gebruik van biomaterialen. 3D bioprinted cardiac patches vertonen mechanische integratie van component sferoïden en zijn zeer veelbelovend in hartweefselregeneratie en als 3D-modellen van hart-en vaatziekten.

Het creëren van cardiale weefsels die mechanische integratie van sferoïden tonen met behulp van 3D bioprinting

Dit protocol beschrijft een netto schimmel gebaseerde methode om te maken van driedimensionale steiger-vrije cardiale weefsels met bevredigende structurele integriteit en synchrone kloppend gedrag.

Een netto schimmel gebaseerde methode van de steiger-free driedimensionale cardiale weefsel schepping

Het huidige protocol genereert mesh-vormige ontworpen cardiale weefsels met cardiovasculaire cellen afkomstig van menselijke geïnduceerde pluripotente stamcellen om het onderzoek van celimplantatietherapie voor hartziekten mogelijk te maken.

Hier beschrijven we een eenvoudig te gebruiken methodologie om 3D zelfgeassembleerde cardiale microtissue-arrays te genereren die zijn samengesteld uit vooraf gedifferentieerde door de mens geïnduceerde pluripotente stamcel-afgeleide cardiomyocyten, cardiale fibroblasten en endotheelcellen. Deze gebruiksvriendelijke en laagcellige techniek die nodig is om cardiale microtissues te genereren, kan worden geïmplementeerd voor ziektemodellering en vroege stadia van medicijnontwikkeling.

Het doel van dit protocol is om de ontwikkeling van een driedimensionaal (3D) microfluïdisch model van sterk uitgelijnd menselijk hartweefsel, samengesteld uit stamcel-afgeleide cardiomyocyten, samen met hartfibblasten (CFs) in een biomimetische, op collageen gebaseerde hydrogel, uit te leggen en aan te tonen, voor toepassingen in hartweefseltechniek, geneesmiddelenscreening en ziektemodellering.

De gepresenteerde methode biedt een innovatieve manier voor het engineeren van biomimetische vezelstructuren in driedimensionale (3D) steigers (bijv. Hartklepblaadjes). 3D-geprinte, geleidende geometrieën werden gebruikt om vorm en afmetingen te bepalen. Vezeloriëntatie en -kenmerken waren individueel instelbaar voor elke laag. Meerdere monsters kunnen in één opstelling worden vervaardigd.

Hier wordt een reeks protocollen gepresenteerd voor het genereren en cryopreservatie van cardiale sferoïden (CSs) uit door de mens geïnduceerde pluripotente stamcel-afgeleide cardiomyocyten gekweekt in een multidimensionaal formaat met hoge doorvoer. Dit driedimensionale model functioneert als een robuust platform voor ziektemodellering, high-throughput screenings en behoudt zijn functionaliteit na cryopreservatie.

Het gebruik van licht om hartcellen en -weefsel te controleren, maakt contactloze stimulatie mogelijk, waardoor de natuurlijke staat en functie van de cellen behouden blijven, waardoor het een waardevolle benadering is voor zowel fundamenteel onderzoek als therapeutische toepassingen.
