Burada, ilk tek hücreli ACMs atriyal remodeling22işaretlenmiş gösteren MetS ile ilgili HFpEF bir fare modeli yalıtım için bir protokol açıklanan.

MetS tip-2 diyabet ve kalp-damar hastalıkları için risk faktörlerinin bir küme tanımlar ve artan bir arteryel kan basıncı içerir (trigliserid yükseltilmiş ve alçaltılmış yüksek yoğunluklu lipoprotein kolesterol) dislipidemi, artan açlık glikoz ve merkezi obezite1. MetS dünya çapında yaygınlık % 25-30 ve sürekli yükselen2olduğu tahmin edilmektedir. HFpEF hànzú bir klinik sendrom genellikle MetS ile ilgili olduğunu. HFpEF ve onun önceki aşamaları (yani, hipertansif kalp hastalığı) sırasında kalp remodeling da kulakçık3/ remodeling tarafından eşlik eder. İndirimli contractile işlevi ve sol atriyum yapısal değişiklikler artmış mortalite, atriyal fibrilasyon ve yeni başlangıçlı kalp yetmezliği4ile ilişkili bulunmuştur. Atriyal remodeling iyon kanal işlevi, Ca2 + homeostazı, atriyal yapısı, fibroblast harekete geçirmek ve doku fibrozu5değişiklikler karakterizedir. Atriyal MetS ile ilgili HFpEF ve onun altında yatan patolojik mekanizmaları hala kötü anlaşılır ve bir daha da derinlemesine araştırma gereken remodeling için yorum yaptı. Hayvan modelleri var olmak a değerli alet ve atriyal kardiyomiyopatiler6,7,8,9alanında birçok gelişmeler yol kanıtlanmıştır.
Çalışmalar izole tek hücreli cardiomyocytes ile teyit ve in vivo bulgular tamamlayıcı için sık sık kullanılır. Bir izolasyon ve potansiyel sonraki hücre kültürü, yollar, iyonik kanal akımları ve uyarma-kasılma-kaplin sinyal soruşturma için izin verir. Fizyolojik koşullar altında cardiomyocytes çoğalırlar değil. Füzyon bir atrial natriuretic faktör transkripsiyon düzenleyici dizisi ve bir simian virüs 40 büyük T antijen transgenik farelerde arasında AT-110adlı ilk ölümsüzleştirdi ACMs yol açtı. AT-1 hücreleri daha da geliştirilmesi sadece seri olarak passaged edemem ama aynı zamanda kendiliğinden sözleşme11HL-1 hücrelere doğuran. Ancak, daha az organize ultrastructure myofibrils11ve bir hyperpolarization harekete geçirmek içe geçerli12geliştirme yüksek bir olay gibi taze izole hücrelere kıyasla yapısal ve işlevsel farklılıklar göstermektedir. Ventrikül cardiomyocytes (VCM) sıçanlar ve fareler modelleri çeşitli yalıtım iyi kurulmuş13,14,15,16,17,18 ' dir , 19. genel olarak eksize kalp Langendorff aparatı monte ve retrogradely bir Ca2 +ile derin-collagenases ve proteaz gibi sindirim enzimleri içeren boş arabellek. Kalsiyum o zaman fizyolojik şartlarda kademeli bir şekilde yeniden ortaya çıkar. Ancak, kullanışlılığı hastalık modelleri atriyal remodeling ile sınırlı olmasına rağmen ACMs yalıtım için adanmış protokolleri kullanılabilir20,21, artan fibrozis ve basınç ilgili farklar nedeniyle.
Bu makalede, bir protokol atriyal remodeling (yani, özellikle ZFS1 fare modeli MetS ile ilgili HFpEF için)22göstermek hayvanlardan atriyal tek hücreli cardiomyocytes yalıtım için hayata geçirdik. Varolan yalıtım protokolleri en iyi duruma getirilmiş ve kontrol ve morfolojik ve fonksiyonel olarak sağlam cardiomyocytes daha yüksek verimleri için önde gelen kardiyak boşluklar, intraluminal basınç değiştirmek için basit, özel yapım bir aygıt tarafından tamamlanmaktadır.

isolation of atrial cardiomyocytes from a rat model of metabolic syndrome-related heart failure with preserved ejection fraction

Bu makalede, biz bir en iyi duruma getirilmiş, Langendorff tabanlı tek hücreli atriyal cardiomyocytes (ACMs) bir fare modeli Metabolik sendromu (MetS) yalıtım için açıklayınız-kalp yetmezliği korunmuş ejeksiyon fraksiyonu (HFpEF) ile ilgili. MetS ile ilgili HFpEF yaygınlığı artıyor ve atriyal remodeling mortalite bağımsız bir tahmin olarak atriyal kardiyomiyopatiler atriyal remodeling ve atriyal fibrilasyon ile ilgili klinik olarak son derece ilgilidir. Çalışmalar izole tek hücreli cardiomyocytes ile teyit ve in vivo bulgular tamamlayıcı için sık sık kullanılır. Dolaşım gemi rarefication ve interstisyel doku fibrozu ACMs başarılı tek hücreli yalıtım bu hastalığın hayvan modeller için potansiyel olarak kısıtlayıcı bir faktör poz.
Biz bu sorunu bir aygıtı el ile yalıtım işlem sırasında kalp boşlukları intraluminal basınç düzenleyen yetenekli istihdam ederek önemli ölçüde morfolojik ve fonksiyonel olarak sağlam ACMs verimini artırma ele sahip. Alınan hücreler, hücre kültürü ve fonksiyonel kalsiyum görüntüleme (yani, uyarma-kasılma-kaplin) gibi farklı deneyler çeşitli kullanılabilir.
Araştırmacı bir adım adım protokolüyle, listesini en iyi duruma getirilmiş çözümler, gerekli ekipman ve kapsamlı sorun giderme Rehberi hazırlamak için ayrıntılı yönergeler sağlar. Yordamın ilk uygulama oldukça zor olabilir, başarılı bir uyum okuyucu MetS ile ilgili HFpEF deneyler geniş bir yelpazede, fare modeli state-of--art ACM izolasyonların gerçekleştirmek izin verir.

21 haftalıkken 60-90 oranında kalsiyum yeniden uyarlaması (adım 5.4-5,7), (adım 6.1 açıklandığı gibi tahmini) uygun ACMs ZSF-1 obez sıçanlarından emir bu Yöntem (Şekil 4A) tarafından ayrılmış olabilir. Rat, farklı bir ve daha fazla hànzú fenotip VCMs24,25ile karşılaştırıldığında ACMs karakterizedir. Şekil 4B korunmuş membranlar ve sarcomere...
