Hücre izolasyonu yöntemi ve sonraki deneyleri pankreas fizyolojik ve patofizyolojik özellikleri incelemek için hangi ile güçlü araçlar temsil burada tasvir. Dağınık pankreas asiner hücreleri izole etmek için yöntemi ilk kez 1972 11 Amsterdam ve Jamieson tarafından tanımlanmıştır. Burada sunulan yöntem Van Acker ve arkadaşları 12 tarafından tarif daha yeni izolasyon yöntemleri uyarlanmıştır. Bu tekniklerin son derece tekrarlanabilir ve kolay öğrenilen olmasına rağmen, ...

Sitozolik kalsiyum dinamik değişiklikler fizyolojik hem de patolojik asiner hücre olayları için gereklidir. Kalsiyumun bu farklı etkileri 1 sinyal kalsiyum farklı mekansal ve zamansal desen kaynaklandığı düşünülmektedir. Örneğin, asinar hücreden enzim ve sıvı salgılamadan yerine 2 alır apikal kutbunun bir kısıtlı bölge kalsiyum sivri bağlantılıdır. Buna karşılık, yoğun olmayan salınımlı kalsiyum sinyalleri tarafından izlenen bir küresel dalga kalsiyum akut pankreatit 3,4 yol patolojik erken olayları ile ilişkilidir. Bu içi asiner proteaz aktivasyonu, düşük enzim salgılanmasını ve asiner hücre hasarı içerir. Bizim laboratuvar in vivo ve in vitro 5-7 hem hastalığına yol bu erken patolojik olayları incelemek için izole pankreas acini kullanır. Burada ayrıntılı olarak açıklanan yöntemler cy ölçmek amacıyla birincil asiner hücrelerin izolasyonu tariftosolic kalsiyum düzeyleri ve hücre hasarı. Bu hücrelerin, adenoviral enfeksiyon için bir yöntem de sağlanmaktadır.
