利用新式生物反應器培養豬腎細胞可行性之評估 / The feasibility using a novel bioreactor to cultivate PK-15 cell孫崇鈞, Chong-Jun Sun January 1994 (has links)
本研究主要在於設計一種新式生物反應器,並應用於生產豬瘟病毒疫苗。首先根據所培養細胞的生長特性與原有生物反應器之缺點,改良成新式的生物反應器,並評估此新式生物反應器適用性、效能,以及所培養豬腎細胞之生長代謝情形與豬瘟病毒力價。整個實驗過程大致分為兩個部分,第一個部分探討細胞固定化培養之最適化培養條件與生長代謝情形,第二個部分探討豬瘟病毒培養之最適化培養條件與生長代謝情形。實驗結果發現豬腎細胞(PK-15)以批次方式培養於新式生物反應器,搭配著FIBRA-CEL®載體,成功的進行擴大培養,豬腎細胞最高的生長量達到2.29×109cells/300mL的細胞量。因此,改良之新式生物反應器可提供細胞優越的生長環境,具有擴大規模培養之潛力,可藉由此簡單設備、操作容易、成本低且低能源消耗之新式生物反應器達成細胞製品之生產基座。 / In this study, the production of PK-15 cell using immobilized animal cell culture in a novel bioreactor was investigated.We evaluated the serviceability and efficiency of a design-improved novel bioreactor for the growth and metabolic states of cultured PK-15 cells and the production of HC virus. The entire experiment includes two major stages: (1) investigation of the optimal conditions and metabolic states for the growth of immobilized cells, (2) investigation of the optimal conditions for the production of HC virus. Our results showed that immobilized PK-15 cells on the fibra-cell carries in the design-improved novel bioreactor exhibited their best growth of 2.29×109 cells/300mL.The immobilized conditions for cell culture, can provide a shearing stress of growth state, easy separation of cells from the culture mediu, and a operation of continuously feeding medium, leading to possibility growth of the high density cell and a long period of production;as a result, the efficiency of producing process is promoted. Here,our design-improved novel bioreactor is expected to provide an optimal growth environment of both the cells and viruses for the production of high-yielded, stable, and consistent cellular biological preparations. Furthermore, it will also provide the basis for the production of cell products with advantages of simple-equipped, easy-to-operate, low cost, and low energy consumption. / 致謝 i
