OBJECTIVE To study the effect of xenotransplantation with pig parathyroid cells, which was prepared using cell microencapsulation technique, on the treatment of hypoparathyroidism in rats without immunosuppressor. METHODS Parathyroid cells were isolated from 10 healthy newborn pigs and encapsulated in alginate-polylysine-alginate (APA) membranes.(More)
Significant problems existing in the islet transplantation include a poor survival ability of the islet cells cultured under static conditions in vitro, decreased secretion function, and limited transplantation efficiency. In this study, we cocultured the three-dimensional (3D) self-assembling peptide nanofiber hydrogel scaffold with the islets from adult(More)
The in vitro culture of pancreatic islets reduces their immunogenicity and prolongs their availability for transplantation. Both simulated microgravity (sMG) and a polyglycolic acid scaffold (PGA) are believed to confer advantages to cell culture. Here, we evaluated the effects of sMG combined with a PGA on the viability, insulin-producing activity and(More)
