제목 Immune Reaction of Purified and Nonpurified Alginate Microcapsules.
초록 Alginate, a polysaccharide extracted from brown seaweed, remains the most widely used biomaterial for immobilizing cells to be transplanted. However, the main drawback is the immune rejection in vivo. To overcome this problem, we have developed using modified Korbutt’s method for alginate purification. After alginate microcapsules manufactured, NIH/3T3 fibroblast and RAW 264.7 macrophage cells were seeded in purified and non-purified alginate microcapsules, and then cell viability were analyzed by MTT assay. RT-PCR was performed to assess mRNA expression for inflammation cytokines such as TNF-α. Alginate microcapsules were implanted into a Wister rat, and the implanted alginate microcapsules were extracted after 1 and 2 weeks. Tissues surrounding implants were harvested and evaluated by histology through H&E and immunohistochemistry through ED-1 staining. This study demonstrates that purified alginate reduce inflammation reaction in vitro and in vivo
