Comparison of Serum-Free Medium AIMV with Standard Serum-Containing Medium in Culturing Cells Activated with IFN-?,IL-2 and Anti-CD3 / 中国肿瘤生物治疗杂志

ABSTRACT

Objective: To compare serum-free medium AIMV with standard serum-containing medium in culturing cells activated with IFN-?,IL-2 and anti-CD3. Methods: Peripheral blood mononuclear cells (PBMC) separated from donors were cultured with IFN-?,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-?; 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.
