    Glossary Serum-Free Medium

    growth medium without animal serum, using specific nutrients instead

    Serum-Free Medium (SFM) is a type of growth medium used in cell culture that does not contain animal serum. Instead, it is supplemented with specific nutrients, hormones, and growth factors tailored to support the growth and maintenance of particular cell types. This allows for more controlled and reproducible experimental conditions, reducing variability and the risk of contamination from unknown serum components.
