Abstract: ObjectiveTo investigate the feasibility of poly l lysne to preparation microencapsules for cell transplantation therapies.MethodsUsing drop generative technique preparation Alginate poly l lysne Alginate (APA) microencapsules containing nerve cell/tissue. The concentration of nerve growth factor in supernatant was detected by two antibody sandwich method of enzyme linked immunosorbent assay.ResultsThe nerve cell/tissue in microencapsules retain reliable cell viability and function. Conclusions The APA is proved with reliable biocompatibility and strength,would work as an immunoisolation tools to exert important function in nerve renovate.

Key words: microencapsules, nerve growth factor, cell transplantation
