Systematic investigation of growth factor needs and effects

Open-access research into growth factors required for proliferation, maintenance, and differentiation of cell types relevant to cultivated meat will support both academic and industry research efforts. This research could include screening of species-specific growth factors under a variety of conditions and in a variety of cell types to characterize cross-species compatibility, which informs commercial efforts to scale production of the most widely used growth factors. Research should also seek to define optimal concentrations of individual growth factors and cocktails for achieving various cell states or behaviors, as well as understanding interactions between growth factors.

Comprehensive microbial screening to identify new protein production candidate strains

Metabolic and physiological characteristics of microbial strains define the commercial potential of any fermentative process, but only a minimal number of strains have been scaled up for commercial production of alternative protein. To broaden the spectrum of available microorganisms, systematic investigation into the physiology of novel microbial strains is needed to identify strains suitable for fermentation.

Computational models of perfusion flow through scaffolds

For tissue-structured cultivated meat production, the transition from the proliferation phase to differentiation phase may involve seeding cells onto a prefabricated scaffold within a perfusion bioreactor. Medium is then perfused through the cell-laden scaffold, providing nutrients and oxygen as cells differentiate and mature. Computational models are needed to describe fluid flow through scaffolds to better understand mass transfer and shear forces. These models will inform considerations for scaffold materials, geometries, dimensions, fabrication methods, and bioprocess design as well as considerations for the composition and viscosity of the medium.

Producing animal-like fats through microbial fermentation

Microbial fermentation provides an efficient method for generating lipid molecules that are chemically identical to those produced by animals. Research efforts are needed to expand current knowledge about the process of engineering the appropriate metabolic pathways for the synthesis of animal lipids into microbial organisms well-suited for large-scale fermentation.

Building workforce capacity through vocational programs

Given the strong and persistent growth in alternative protein production, the industry has a pressing need for a trained workforce. Technical colleges should establish programs to help train the next generation of alternative protein workforces and build a talent pipeline for the industry.
