1. Preparing H9c2 cardiomyoblast cells
H9c2 rat cardiomyoblasts were obtained from ATCC (Wesel, Germany) and expanded in high glucose (4.5 g/L) DMEM containing 10% fetal bovine serum, 4 mM L-glutamine, 100 U/ml penicillin and 100 &mu;g/ml streptomycin. The H9c2 myoblast cell line is derived from embryonic rat heart, it is used as an in vitro model for both skeletal and cardiac muscle 8,9.
Prepare 12 well plate of H9c2 cells:

stem cell transplantation in an in vitro simulated ischemia/reperfusion model

Kök hücre naklinin klinik pratikte 1,2,3 kendi yolunu buluyor. , Daha iyi sonuçlar elde protokolleri daha güçlü hale getirmek ve implante edilebilir piller için yeni kaynaklar bulma 4,5 son araştırma odağı . Hücre tedavileri etkinliğinin incelenmesi kolay bir iş değildir ve yeni araçlar, tedavi sürecinin 6 katılan mekanizmalarının araştırılması için ihtiyaç vardır . Iskemi / reperfüzyon deneysel bir protokol, ve kök hücre nakli sonrası iskemi / reperfüzyon sırasında hücresel bağlantıları ve hatta hücre içi mekanizmaları gözlem izin ve hücre tedavisinin etkinliğini değerlendirmek amacıyla tasarlanmıştır. H9c2 cardiomyoblast hücreleri, hücre kültürü plakaları 7,8 üzerine yerleştirilir . İskemi glikoz serbest bir ortamda% 0.5 altında oksijen seviyesi ile 150 dakika ile simüle edildi. Sonra, normal medya ve oksijen seviyesi reperfüzyon simüle etmek için tekrar edilmiştir. Oksijen glikoz yoksunluk sonra,hasarlı hücreleri kültürüne ekleyerek elde edilen mezenkimal kök hücreler işaretli insan kemik iliği nakli ile tedavi edildi. Mezenkimal kök hücreleri, minimal invaziv cerrahi ile kolayca erişilebilir, kolayca genişletilebilir ve otolog, çünkü klinik çalışmalarda tercih edilir. Eş-yetiştiriciliği 24 saat sonra, hücreler canlı ve ölü hücrelerden ayırt etmek Calcein ve ethidium-homodimer ile boyandı. Bu kurulum bize konfokal floresan mikroskobu kullanarak hücrelerarası bağlantıları araştırmak ve postiskemik hücreler flow sitometri ile hayatta kalma oranını ölçmek için izin verdi. Mikroskopisi gibi hücre füzyon ve hücrelerarası nanotüpler oluşumu gibi iki hücre popülasyonlarının etkileşimleri gösterdi. Flow sitometri analizi hasarlı hücrelerinin bir grafik üzerinde çizilen ve istatistiksel analiz edilebilir 3 kümeleri ortaya çıkardı. Bu kesimler ayrı ayrı araştırılmalıdır ve sonuçlar simüle etkinliğini bu veriler üzerinde çizilebilirterapötik yaklaşım.
