Il metodo di isolamento delle cellule e saggi successivi raffigurati qui rappresentano potenti strumenti con cui studiare le caratteristiche fisiologiche e fisiopatologiche del pancreas esocrino. Il metodo per isolare le cellule acinose pancreatiche dispersi è stato descritto da Amsterdam e Jamieson nel 1972 11. I metodi qui presentati sono stati adattati da più recenti metodi di isolamento descritte da Van Acker e colleghi 12. Sebbene queste tecniche sono altamente riproducibili e facilmente app...

Cambiamenti dinamici nel calcio citosolico sono necessari per gli eventi delle cellule acinose sia fisiologiche che patologiche. Questi effetti divergenti di calcio sono pensati per derivare da diversi modelli spaziali e temporali di calcio di segnalazione 1. Per esempio, enzimi e la secrezione fluido dalla cellule acinose sono legate a picchi di calcio da una regione ristretta del polo apicale in cui la secrezione avviene 2. Al contrario, un&#39;onda calcio globale seguito da intensi segnali di calcio non-oscillatorie è associato ad eventi patologici precoci che portano alla pancreatite acuta 3,4. Questi includono attivazione intra-acinare proteasi, enzima secrezione ridotta e danno cellulare acinare. Il nostro laboratorio utilizza isolato acini pancreatici per studiare questi eventi patologici precoci che portano alla malattia, sia in vivo che in vitro 5-7. I metodi qui descritti descrivono isolamento di cellule acinose primarie a scopo di misurare cylivelli di calcio tosolic e lesioni delle cellule. Viene inoltre fornito un metodo per l&#39;infezione adenovirale di queste cellule.

preparation of pancreatic acinar cells for the purpose of calcium imaging, cell injury measurements, and adenoviral infection

L&#39;cellule acinose pancreatiche è il principale parenchima cellulare del pancreas esocrino e svolge un ruolo primario nella secrezione di enzimi pancreatici nel dotto pancreatico. E &#39;anche il sito per l&#39;avvio di pancreatite. Qui si descrive come le cellule acinose sono isolati da tutto il tessuto del pancreas e dei segnali intracellulari di calcio sono misurati. Inoltre, si descrivono le tecniche di trasfezione queste cellule con costrutti adenovirali, e successivamente misurando la fuoriuscita di lattato deidrogenasi, un marker di danno cellulare, in condizioni che inducono lesioni cellule acinose in vitro. Queste tecniche forniscono un potente strumento per la caratterizzazione delle cellule acinose fisiologia e patologia.

Un esempio di misurazioni calcio delle cellule acinose in risposta a stimoli fisiologici è fornita in figura 3. Cellule acinose state caricate con il colorante calcio Fluo-4 e perfusi con l&#39;acetilcolina analogico carbachol (CCH, 1 mM)) 8. Cellule risposto nella forma di un&#39;onda di calcio che avvia nella regione apicale e propaga alla regione basolaterale 3,9.
