    Area of Science:

    • Biotechnology
    • Cell Biology
    • Bioprocess Engineering

    Background:

    • Mammalian cell culture requires suitable microcarriers for growth and product formation.
    • Anchorage-dependent cells necessitate surfaces that mimic natural environments.
    • Developing cost-effective and efficient microcarriers is crucial for biopharmaceutical production.

    Purpose of the Study:

    • To evaluate commercially available DEAE-cellulose microcarriers as substrates for mammalian cell culture.
    • To assess the suitability of these microcarriers for producing mouse interferon.
    • To compare the interferon yield from cells cultured on microcarriers with traditional monolayer cultures.

    Main Methods:

    • Investigated microgranular anion exchange DEAE-cellulose (DE-52, Whatman) as a microcarrier.
    • Cultured CCL-1 mouse cell line on the DEAE-cellulose microcarriers.
    • Induced mouse interferon production using Sendai virus.

    Main Results:

    • Successfully cultured CCL-1 mouse cells on DEAE-cellulose microcarriers.
    • Achieved successful production of mouse interferon following viral induction.
    • Observed interferon yield per cell comparable to that obtained in conventional monolayer cultures.

    Conclusions:

    • DEAE-cellulose microcarriers are a viable substrate for culturing anchorage-dependent mammalian cells.
    • These microcarriers support efficient production of biologically active molecules like mouse interferon.
    • DEAE-cellulose offers a promising alternative for scalable mammalian cell-based bioproduction.
