Innovativi o solo un altro protocollo cultura pulcino? Con l&#39;ex-shell meno protocolli di cultura 1-4 il tasso di sopravvivenza totale degli embrioni pulcino erano basse, ad esempio ca. 30% 1. Il raffinato protocollo cultura ex ovo descritto in questo articolo video, al contrario, permette di tassi di sopravvivenza oltre il 50%. Rispetto al classico nelle culture cultura ex ovo ovo di embrioni di pollo facilita in modo significativo l&#39;a...

chick ex ovo culture and ex ovo cam assay: how it really works

Uova di gallina nella prima fase di allevamento sono tra dati in vitro e in vivo e sistemi di fornire un ambiente di test vascolare non solo per studiare l&#39;angiogenesi, ma anche per studiare tumorigenesi. Dopo la membrana pulcino corioallantoidea (CAM) ha sviluppato, la sua rete di vasi sanguigni possono essere facilmente accessibili, manipolato e osservato e quindi fornisce un ambiente ottimale per le analisi angiogenesi. Dato che il sistema linfatico non è completamente sviluppato fino ultime fasi di incubazione, l&#39;embrione di pollo serve come ospiti naturali immunodeficienti in grado di sostenere i tessuti e le cellule senza innestato specie-specifiche restrizioni. Oltre a coltivare lo sviluppo di allo-e xenotrapianti, la rete di vasi sanguigni CAM offre un ambiente unico e di sostegno per intravasation delle cellule tumorali, la diffusione e l&#39;arresto vascolare e un archivio in cui le cellule arrestato stravaso di formare micro foci metastatici. A fini sperimentali, nella maggior parte degli studi recenti la CAM è stata esposta dal taglio di una finestra attraverso il guscio dell&#39;uovo e gli esperimenti sono stati condotti in ovo, con conseguente limitazione significativa l&#39;accessibilità del CAM e le possibilità di osservazione e documentazione fotografica degli effetti. Quando la shell-less culture del embrione di pollo sono stati usati 1-4, nessun dettaglio sperimentale sono state fornite e, se pubblicate in tutti, i tassi di sopravvivenza di queste culture erano basse. Abbiamo raffinato il metodo della cultura ex ovo di embrioni di pollo in modo significativo, introducendo un estrusione razionalmente controllata del contenuto dell&#39;uovo. Queste culture ex ovo migliorare l&#39;accessibilità dell&#39;embrione CAM e pulcino, consentendo un facile nella documentazione in vivo degli effetti e facilitare la manipolazione sperimentale dell&#39;embrione. Questo consente l&#39;applicazione di successo a un gran numero di questioni scientifiche: (1) Come un saggio angiogenesi migliorato 5,6, (2) un set up sperimentale per preparazioni iniettabili facilitato nel vitreo dell&#39;occhio embrione di pollo 7-9, (3) come ambiente di test per la diffusione e intravasation di dispersi cellule tumorali da linee cellulari stabilizzate inoculati sul CAM 10-12, (4), un sistema migliore per sostenere il trapianto di successo e la cultura delle gemme degli arti di pollo e topi 13 come pure (5 ) per l&#39;innesto, propagazione, e ri-innesto di solido tessuto tumorale primaria ottenute da biopsie sulla superficie del CAM 14. In questo articolo video che descrivono la creazione di una cultura raffinata ex pulcino ovo e test CAM con tassi di sopravvivenza oltre il 50%. Oltre che fornire una dimostrazione passo passo per l&#39;applicazione di successo della cultura ex ovo per un gran numero di applicazioni scientifiche. Daniel S. Dohle, Susanne D. Pasa, e Sebastian Gustmann contribuito in maniera uguale a questo studio.
