ABSTRACT
Objective To develop a method of adult porcine pancreatic islet isolation.Methods The tails of adult porcine pancreas were perfused through the pancreatic duct with 0.1% cold collagenase(type Ⅺ) and incubated at 38.5 ℃.The digested tissue was dispersed in 4 ℃ Hanks balanced salt solution(HBSS).The tissue suspensions were filtered through a 600 ?m mesh.The residual tissue was resuspended in cold HBSS,and put in the Ricordi’s chamber and shaken for 5 minutes,then filtered again.The isolated islets were divided into three groups: control group( n =14),Pefabloc(trypsin inhibitor, n =8) group and FOY(trypsin inhibitor, n =5) group.The collagenase solution of the Pefabloc and FOY group was supplemented with 1.0 mmol/L Pefabloc and FOY respectively. Results The islet yields of the Pefabloc group and FOY group 〔(11 848?3 530) islet/g pancreas and (14 496?3 693) islet/g pancreas〕 were significantly higher than that of the control group 〔(8 505?3 349) islet/g pancreas〕, P
