Abstract
To obtain long-term storage of cell-encapsulated alginate-PLO-alginate (APornA) microcapsules, the influences of storage temperatures on the microcapsule morphology, cell viability and metabolic activities were investigated. The results showed that the microcapsules exhibited the original morphological characteristics with smooth surface, good sphericity and overall integrity after 4 weeks preserved in liquid N2. 4°C and -20°C were presented to be the harsh conditions for cell propagation and the secretion of metabolic products compared to -80°C and -196°C. It can be concluded that lower temperature is beneficial for the cell recovery. These results supplied supplementary data for poly- L-ornithine (PLO) as a potential coating material in the future cell microencapsulated applications.
