RESULTS: Islets isolated and digested were stained red by dithizone and no stain was observed in the islet exocrine gland. The purity of islets was ≥ 85%. The results of MTT and functional detection showed that the survival rate of islets in the scaffold group was significantly higher than control group (P 0.05). The observation under scanning electron microscopy demonstrated that islets tightly adhered to the PGA scaffolds and grew in the three-dimensional status.

结果：分离和消化后的胰岛被双硫腙染成红色，胰岛外分泌腺不着色，胰岛纯度≥85%；MTT及胰岛功能检测结果显示，支架组的胰岛成活率及胰岛功能明显增高，与对照组相比差异有显著性意义(P 0.05)；扫描电镜观察，胰岛紧密黏附在聚乙醇酸支架上，支架上胰岛成三维立体生长。
