non-invasive imaging of leukocyte homing and migration in vivo

İki foton (2P) mikroskobu, yüksek çözünürlüklü bir görüntüleme tekniği geniş biyologlar tarafından adapte edilmiştir. 2P mikroskopi değeri dokulara içinde ve canlı farelerde hücre davranışları ile ilgili zengin Spatiotemporal bilgi sağlar. Lökosit işe host enfeksiyona karşı savunma ve ne zaman kontrolsüz önemli bir rol oynar, inflamatuar ve otoimmün hastalıklar için katkıda bulunabilir. Hücreler, ışık saçılması dokular içinde derin bulunan gemiler içinde hızla hareket ediyor bu yana, in vivo olarak lökosit işe incelenmesi teknik olarak çok zordur. Bugüne kadar, en intravital görüntüleme çalışmaları, kan damarları ve dokuların ortaya çıkarmak için cerrahi hazırlık gerektirir. Cerrahi kendisi tarafından indüklenen doku hasarı ve inflamasyon önlemek için, burada, biz fare Kapkaççı ve bilek lökosit ticaretini incelemek için kullanılabilecek bir tek hücreli non-invaziv görüntüleme yaklaşımı tanımlar. Biz, bizim 2P görüntüleme hazırlık teknik yönlerini tartışmak ve yürütme ve veri toplama için kurulmuş ilk tipik bir deney yoluyla okuyucu yürümek.
