Mikro büyüklükteki parçacıklar yönetim hayvan bir organizma içine ilaç ve aşı teslim1, damarlara görselleştirme2, transgenik hücre implantasyonu3ve küçük optik sensör implantasyon gibi alanlarda önemli bir görevdir 4 , 5. ancak, implantasyon yordam microscale parçacıklar halinde küçük Laboratuvar hayvanlarının damar sistemi için özellikle hassas Sucul organizmalar için zordur. Zebra balığı gibi popüler araştırma numuneler için bu tavsiye edilir bu yordamları açıklık video protokollerini kullanarak.
İntrakardiyak ve kapiller microinjections'microobjects dır zebra balığı kana eğitimli personel ve benzersiz mikrocerrahi özellikleri gerektirir. Daha önce bir retro-orbital el ile enjeksiyon3 tüm hücreleri yönetim için kolay ve etkili bir yöntem olarak önerilmiştir. Ancak, deneyim, göz kılcal ağ küçük alanı nedeniyle bu teknik üzerinden istenilen sonucu elde etmek için çok pratik alır.
Burada, biz güçlü ve verimli microparticle implantasyon dolaşım sistemi içine için bir yöntem yetişkin zebra balığı, böbrek dokusunun içine doğrudan el ile enjeksiyonla kılcal damar ve böbrek damarlarının açısından zengin olduğu açıklanmaktadır. Bu teknik zebra balığı böbrek6içine hücre transplantasyonu için video protokolünü dayanır ama travmatik ve zaman alıcı mikrocerrahi adımları elendi. Önerilen yöntem tarafından düşük mortalite ile karakterizedir (0-%20) ve yüksek verimlilik (% 70-90 başarı) ve yaygın olarak bulunan cihazlar kullanılıyor Enstitü kolaydır.
Hangi enjeksiyon kalite, sayısı bir kaba göreli değerlendirme doğrulanmasına izin verir (floresan veya renkli olmaları durumunda) implant microparticles gill kılcal damarlar içinde görselleştirme önerilen protokol önemli bir parçası olduğunu enjekte parçacıklar ve dolaşımdaki kandan doğrudan fizyolojik ölçümler için spektral sinyal algılama. Açıklanan tekniği olası uygulamaları bir örnek olarak, biz SNARF-1, ilk olarak önerilen Borvinskaya bir microencapsulated floresan sonda kullanarak zebra balığı kan pH vivo ölçümleri için protokol göstermek ve ark. 20175.

simple and effective administration and visualization of microparticles in the circulatory system of small fishes using kidney injection

Canlı bir organizma içine mikro büyüklükteki parçacıkların yönetim sistemik damarlara görselleştirme, ilaç ve aşı teslim, transgenik hücreleri ve küçük optik sensörler implantasyonu için uygulanabilir. Ancak, biyolojik ve veteriner laboratuvarları çoğunlukla kullanılan, küçük hayvanların içine intravenöz microinjections çok zor ve eğitimli personel gerektirir. Burada, biz balık böbrek içine enjeksiyon tarafından microparticles giriş yetişkin zebra balığı (Danio rerio) dolaşım sistemi içine için sağlam ve verimli bir yöntem göstermek. Damarlara tanıtılan microparticles görselleştirmek için balık solungaçları basit bir intravital görüntüleme tekniği öneriyorum. Vivo zebra balığı kan pH kontrolü başarılı bir enjekte microencapsulated floresan kullanarak sonda, SNARF-1, açıklanan tekniği mümkün uygulamalarından birini göstermek için. Bu makalede pH duyarlı boya encapsulation ayrıntılı bir açıklamasını ve hızlı enjeksiyon prensipleri ve görselleştirme floresan sinyali VIVO içinde kayıt için elde edilen microcapsules gösterir. Enjeksiyon önerilen yöntemi düşük mortalite oranı ile karakterizedir (0-%20) ve yüksek verimlilik (% 70-90 başarı) ve yaygın olarak bulunan cihazlar kullanılıyor Enstitü kolaydır. Tüm açıklanan yordamları süs balıkları ve medaka gibi diğer küçük balık türleri üzerinde gerçekleştirilebilir.

Elde edilen sonuçları sunulan Protokolü üç ana kategoride birinden gelir: bir floresan boya (Şekil 1), microcapsules daha fazla görselleştirme ile böbrek enjeksiyon encapsulation tarafından floresan microparticles oluşumu Gill kılcal damarlar (Şekil 2 ve 3) ve pH seviyeleri (Şekil 4) kan son olarak, in vivo spektral kayıt SNARF-1 floresans iz...
