Abstract :Type 1 diabetes is clinically characterized as the loss of control of glucose homeostasis due to the reduced number of insulinproducing cells. Long-term glycemic control after implantation could be maintained by preserving the cell viability and tissue-specific functions during the process of microencapsulation. In this study, alginate solution was supplemented with platelet-rich plasma insert ignore into journalissuearticles values(PRP); to improve the viability and preserve the cell functions during the encapsulation of a beta cell line insert ignore into journalissuearticles values(BRIN-BD11);. Cell viability was assessed and insulin secretion and insulin stimulation index were evaluated. The polymerization of alginate with PRP enhanced the viability up to 61% in the alginate microbeads. PRP supplementation to the alginate composition not only increased the number of viable cells by 1.95-fold, but the insulin secretion also improved by about 66%. The stimulation index, however, was not affected by the PRP supplementation.Keywords : Calcium alginate microbeads, diabetes, droplet method, pancreatic beta cells, insulin
