摘要
目的 :多方面比较无血清培养基AIMV与完全培养基对体外诱导免疫细胞支持作用。方法 :分别用AIMV及完全培养基在IFN γ ,IL 2 ,及抗 CD3单抗存在的条件下培养人外周血单个核细胞 ,比较细胞的增殖能力、细胞表型、及细胞因子分泌能力 ,并比较不同培养基培养细胞回输体内后的抑制病毒效果。结果 :与完全培养基培养细胞相比 ,无血清培养基AIMV培养细胞增殖能力与之相当 ;CD2 5的表达率增高 ,表达持续时间延长 ;细胞因子IFN γ的分泌时间延长 ;回输体内后的抑制病毒作用更明显。结论 :无血清培养基AIMV用于培养临床治疗用的免疫细胞 ,综合效果优于完全培养基。
Objective: To compare serum-free medium AIMV with standard serum-containing medium in culturing cells activated with IFN-γ,IL-2 and anti-CD3. Methods: Peripheral blood mononuclear cells (PBMC) separated from donors were cultured with IFN-γ,IL-2 and anti-CD3 in serum-free medium AIMV or in standard serum-containing medium separately. Proliferation, phenotypes and cytokine secretion of cells cultured in the two different media were compared. The inhibitory effects on hepatitis B virus replication in vivo were observed after transfusion of cells cultured in different media. Results: Compared with cells cultured in standard serum-containing medium, cells cultured in serum-free medium AIMV could proliferate well enough to be applied to immunotherapy; More percentage of cells cultured in AIMV expressed CD25; Cells cultured in serum-free medium secreted more IFN-γ; After transfusion of cells cultured in AIMV, hepatitis B replication could be inhibited more evidently. Conclusion: Serum-free medium AIMV was better than serum-containing medium in culturing cells for immunotherapy.
