Laboratory study demonstrates optimized culture conditions enhance interferon yields in microcarrier-grown fibroblasts, highlighting a viable method for large-scale production.

Key Points

To identify optimal culture and superinduction parameters to maximize human interferon production using FS-4 fibroblast cells grown on microcarriers.
Assessed the effects of cycloheximide and actinomycin D concentrations and exposure times during superinduction in microcarrier-cultured FS-4 human fibroblasts.
Evaluated culture conditions including serum concentration (2.5% to 20%), incubation temperature kinetics (30°C, 34°C, and 37°C), and interferon priming (50 U/ml for 16 h).
Optimal induction occurred with 10 µg/ml each of cycloheximide (5–6 h exposure) and actinomycin D (≥2 h exposure), with lower serum concentrations (2.5% and 5%) producing higher yields than 10% and 20%.
Significantly higher interferon yields were obtained at 34°C compared to 30°C or 37°C, and priming with 50 U/ml interferon for 16 h consistently boosted output.
Combining these optimized parameters enabled consistent interferon yields exceeding 20,000 international units per 10^6 cells.
