Growth factors for cellular agriculture including cultivated meat, dairy and seafood

Cellular agriculture has the potential to transform food production and impact the health and well-being of future generations. Immediate priorities for cultivated meat and dairy process development include optimizing serum-free cell culture media to support cell expansion and maturation stages in bioreactor conditions. Replacing animal-derived components, particularly fetal bovine serum (FBS), is essential for consistent performance, to remove the risk of contamination from viruses or prions and opens opportunities for fine-tuning of culture conditions. Growth factors are critical components of cell culture media and provide a carefully orchestrated set of biochemical signals to control cell growth and fate. High purity, animal-free and optimized growth factors produced in an efficient microbial fermentation process provide the most reliable solution for cultivated meat and cellular agriculture. We provide extensive CoO, CoA and animal-free (AOF/ADCF) documentation, bulk pricing, stock reservation service and opportunities for collaboration to support this important field.

Product focus: animal-free cell culture with HGF natural isoform NK1

The NK1 isoform is the smallest naturally occurring splice variant of HGF, it comprises the HGF N-terminal and first kringle domain. Qkine HGF NK1 is also completely animal-free (AOF), making it suitable for chemically defined media and reproducible scale-up. This isoform promotes efficient differentiation of human iPSCs at just 10 ng/ml.
