© 2016 Future Science Ltd. Background: Pancreatic ß-cell microencapsulation using sodium alginate (SA), polylornithine (PLO) copolymers, and ultrasoluble hydrogels, polystyrenes and polyallamines (PAA), has been heavily studied. However, long-term success remains limited due to poor macrocapsules' physical properties and cell functions. Our study aimed to incorporate percentages of PAA and ursodeoxycholic acid, into SA and PLO dispersion mixture and examine best microencapsulating methods and best macrocapsules containing ß-cells. Methods/results: Microencapsulating parameters were examined and the Flow-Vibrational Nozzle built-in system was screened and found to be most efficient at high frequency (1900 Hz). Macrocapsules were produced with or without ursodeoxycholic acid in percentages: 0.018SA:0.01PLO:0.005PAA:0.04ursodeoxycholic acid (up to 100% H2O). Using the refined microencapsulation method with vibrational frequency of 1900 Hz, macrocapsules with ursodeoxycholic acid had optimized cell viability and biological functions and ameliorated inflammatory biomarkers. Conclusion: High frequency and air-pressure with Flow-Vibrational encapsulation using the mixture: 0.018SA:0.01PLO:0.005PAA:0.04ursodeoxycholic acid resulted in better cell biology suggesting potentials in ß-cell transplantation. | |
