Metastaser är den vanligaste dödsorsaken hos cancerpatienter. Det handlar om fyra viktiga steg: avskiljandet av cancerceller från deras primära loci, sättas i omlopp (intravasation), deras utträde ur cirkulation (extravasation), och överlevnad och tillväxt i en avlägsen orgel. Metastaser i mänskliga anses vara en långsam process och ofta manifesteras efter år av latens. Att studera dess progression i tid, var det ovanstående relativt snabbt experimentell analys etablerat i immundefekta möss. 4 S...

experimental metastasis assay

Metastaser är den vanligaste dödsorsaken hos cancerpatienter. För att förstå mekanismen av metastaser, var en experimentell metastaser analys fastställts med nedsatt immunförsvar möss. Denna artikel skisserar de förfaranden som ingår i denna analys, inklusive provberedning, intravenös injektion och celler odling av lungmetastaser. Kortfattat var ett förutbestämt antal mänskliga cancerceller förberedda<em&gt; In vitro</em&gt; Och sprutas direkt in i cirkulationen av immundefekta möss genom sin svans ådror. Ett litet antal celler överlever turbulensen i omlopp och växa som metastaser i inre organ, exempelvis lunga. Den injicerade möss är dissekeras efter en viss tid. Vävnaden distribution av metastaser bestäms enligt en dissekera mikroskop. Antalet metastaser i en specifik vävnad räknas och det direkt korrelerar med metastaserande förmåga injicerade cancerceller. Den uppkomna metastaser är isolerade och odlade<em&gt; In vitro</em&gt; Som cellinjer, som ofta visar förbättrade metastaserande förmågor än föräldrarnas linje när det injiceras igen till nedsatt immunförsvar möss. Dessa mycket metastaserande derivat bli användbara verktyg för att identifiera gener eller molekylära vägar som reglerar metastaserande progression.
