Ultrason kontrast ajanlar geç evre gebelik fare embriyoları ve doğrusal olmayan kontrast görüntüleri enjekte edildi perfüzyon parametreleri ölçmek için edinilen ve bağlayıcı Kabarcığa hedef alındı. Embriyonik damar sistemi içerisinde mikro-kabarcıkların başarılı görüntüleme bir dizi faktöre, ilk olarak embriyo canlılığı bağımlıydı. Tüm ekipman ve cihaz enjeksiyonun başlangıcında rahim embriyoların izolasyonu için gerekli olan zamanı en aza indirmek için önceden hazırlanmışt...

Kontrastlı ultrason görüntüleme görselleştirmek ve damar ortamı karakterize etmek kabarcık kontrast maddelerin kullanımını kolaylaştırır. Bu ajanlar mikrosirkülasyon, damarlanma ve kardiyovasküler fonksiyonu noninvaziv değerlendirmesini sağlar. Buna ek olarak, baloncuk yüzeyinin modifikasyonu mümkün vasküler olay moleküler ultrason görüntüleme yapmak anjiyojenez, ateroskleroz ve inflamasyon 1,2 klinik öncesi uygulamalarda gösterildiği gibi, endotelyal biyolojik bağlanma hedeflenen mikro-sonuçlanabilir. Kontrastlı ultrason nedenle de sağlıklı ve hastalıklı damar durumları 3-5 etkileyen karmaşık ve çeşitli ortamlar belirlemek için kullanılabilir. Yıl geçmiş sayıda, kabarcık görüntüleme programı ilgi yönlü fare embriyo modeli genişletmiştir. Memeli bir gelişme modeli olarak, embriyonik damar içine kabarcıkların giriş fizyolojik artırırGelişmekte olan dolaşım sistemi (örneğin, kan akımı, kardiyak output) ve transgenik durumlarda ve kalp hastalığı 6,7 hedeflenen mutant fare modellerinde, çalışma kardiyovasküler fonksiyonu nasıl değiştirdiğini genetik faktörler anlayışlar verebilir. Aslında, nicel ve nitel 2D embriyonik beyin damar analizleri zaten 8 elde edilmiştir. Bundan başka, fare embriyosu canlı dokuda vasküler belirteçlerle hedeflenen mikro-kabarcıklar bağlanmasının incelenmesi için mükemmel bir model olarak sunulur. Bartelle ve diğ. 9, örneğin, Biotag-BirA transgenik embriyo bağlanma ve damar anatomisinin incelemek hedeflenen değerlendirir embriyo kalp ventriküllere, avidin mikro-kabarcıkları getirmiştir. kliniğe Bu teknik çeviri önemli bir kriter - heterozigot ve homozigot fare modelleri üretimi de moleküler ultrason kantitatif tabiatının belirlemek amacıyla yapılan tümör modeli araştırmaları için bir vekil olarak kullanılabilir edilebilir. 8-10 aracılığıyla maruz tek embriyo içi kardiyak enjeksiyonlar aracılığıyla embriyonik dolaşıma tanıtıldı. utero enjeksiyonları Ancak, bir takım zorluklarla karşı karşıya. Bu enjeksiyon rehberlik, anne ve batın embriyo hareketi karşı ihtiyacını, anne hemodinamik canlılığının bakım ve 11 kanama nedeniyle anestezi ve komplikasyon uzun vadeli etkileri ele batın embriyolar içerir. Bu nedenle, soruşturmanın amacı izole yaşayan geç evre embriyoların 12 içine mikrokabarcıkları enjekte için bir teknik geliştirmek oldu. Bu seçenek, enjeksiyon kontrol ve konumlandırma, tıkanma olmadan görüntüleme uçağın tekrarlanabilirlik ve basitleştirilmiş görüntü analizi ve ölçümü açısından daha fazla özgürlük sunuyor. Bu çalışmada, biz fo yaşayan kemirgen embriyolara kabarcıkların enjeksiyon için yeni bir prosedür anahatr kabarcık kinetik davranışları okuyan ve amaçları endojen endotel yüzey belirteçleri bağlayıcı Kabarcığa hedeflenen Derslerinizi. Lineer olmayan bir kontrast özel ultrason görüntüleme tepe geliştirilmesinde uygulanmıştır (PE), yıkama-oranı ve süresi izole E17.5 embriyolar (TTP) tepe dahil olmak üzere temel perfüzyon bir dizi parametre ölçülmesi için kullanılır. Bu, aynı zamanda, aktif bir anjiyojenez 13 bölgelerinde damar endotel hücrelerinde yüksek ifade için endoglin klinik olarak anlamlı bir hedef işlev transjenik fare modeli, bir embriyonik endoglin kaybına moleküler ultrason kantitatif tabiatının değerlendirmek için embriyo modelinin geçerliliğini göstermek . endoglin hedefli (MB E) fare izotip IgG2 kontrol (MB C) ve hedefsiz (MB U) mikro-kabarcıkların yapışma heterozigot endoglin (İngilizce +/-) ve homozigoz endoglin (İngilizce + / +) sentezleyen embriyolar değerlendirilir. Hedeflenen bindinin analizing moleküler ultrason endoglin genotipleri arasında ayırt ve ölçülebilir moleküler ultrason seviyelerine reseptör yoğunlukları ilgili yeteneğine sahip olduğunu ortaya koymaktadır.

contrast imaging in mouse embryos using high-frequency ultrasound

Ultrasound contrast-enhanced imaging can convey essential quantitative information regarding tissue vascularity and perfusion and, in targeted applications, facilitate the detection and measure of vascular biomarkers at the molecular level. Within the mouse embryo, this noninvasive technique may be used to uncover basic mechanisms underlying vascular development in the early mouse circulatory system and in genetic models of cardiovascular disease. The mouse embryo also presents as an excellent model for studying the adhesion of microbubbles to angiogenic targets (including vascular endothelial growth factor receptor 2 (VEGFR2) or &#945;v&#946;3) and for assessing the quantitative nature of molecular ultrasound. We therefore developed a method to introduce ultrasound contrast agents into the vasculature of living, isolated embryos. This allows freedom in terms of injection control and positioning, reproducibility of the imaging plane without obstruction and motion, and simplified image analysis and quantification. Late gestational stage (embryonic day (E)16.6 and E17.5) murine embryos were isolated from the uterus, gently exteriorized from the yolk sac and microbubble contrast agents were injected into veins accessible on the chorionic surface of the placental disc. Nonlinear contrast ultrasound imaging was then employed to collect a number of basic perfusion parameters (peak enhancement, wash-in rate and time to peak) and quantify targeted microbubble binding in an endoglin mouse model. We show the successful circulation of microbubbles within living embryos and the utility of this approach in characterizing embryonic vasculature and microbubble behavior.
