    Area of Science:

    • Biotechnology
    • Cell Biology
    • Biomaterials

    Background:

    • Anchorage-dependent cell propagation is crucial for various biological applications.
    • Current methods can be time-consuming, expensive, and apparatus-intensive.
    • Developing efficient cell culture surfaces is an ongoing challenge.

    Purpose of the Study:

    • To develop and evaluate a novel positively charged dextran microsphere for cell culture.
    • To assess the microsphere's efficacy in supporting anchorage-dependent cell attachment and growth.
    • To demonstrate the advantages of this microcarrier system for cell propagation.

    Main Methods:

    • Synthesis of positively charged dextran microspheres.
    • Culturing of anchorage-dependent cells (chicken embryo fibroblasts, human fibroblasts) on the microspheres.
    • Quantification of cell saturation concentrations.

    Main Results:

    • The developed microspheres provide an excellent surface for cell attachment and growth.
    • Routine saturation cell concentrations exceeding 4 x 10^6 cells/ml were achieved.
    • Successful propagation of both chicken embryo fibroblasts and normal diploid human fibroblasts was demonstrated.

    Conclusions:

    • Positively charged dextran microspheres are effective microcarriers for anchorage-dependent cells.
    • This microcarrier system significantly improves the efficiency of cell propagation.
    • The method offers a reduced-time, lower-cost, and less complex alternative for routine cell culture.
