Growth factors from conditioned cell culture media
Rather than relying on recombinant growth factors, cultivated meat companies could use conditioned media from animal cells producing high levels of these molecules.

More frameworks for academic-industry collaboration could help build talent pipelines, create research commercialization pathways, and drive alignment on research priorities.
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.
Fat and moisture retention are critical to the organoleptic properties of meat and must be perfected across all alternative protein platforms. Solutions for encapsulating fat and moisture are necessary to ensure that these components are protected from damage or loss throughout manufacturing, storage, cooking, and mastication.
In strain development, many of the selectable markers confer traits like antibiotic or herbicide resistance. While some auxotrophic selection markers exist, these are often not orthogonal and thus not amenable to stacking for multi-trait selection.
An alternative protein data lake could contain anonymized data from processing runs across many manufacturers, informing processing improvements and aiding process failure troubleshooting.
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.
A number of cellular processes occurring after slaughter are known to affect the quality and sensory properties of conventional meat. Cultivated meat will offer unprecedented control over these parameters and therefore over the quality of the final product, but it is critical to understand exactly how post-harvest processes for cultivated meat can or should differ from post-slaughter processes in conventional meat. This research can enable subsequent innovations in bioprocess design, media formulation, cell line development, or harvesting techniques to confer consistently high levels of meat quality from cultivated meat processes.
Development of humanely-sourced and thoroughly documented and characterized cell lines from a variety of common food species—together with a mechanism for licensing and distributing these lines to researchers and companies—will remove a key barrier to entry into the field of cultivated meat. In addition, development of open-access, standardized protocols for performing cell isolation from a variety of source tissues and establishing robust cell lines will streamline the processes for those who do end up needing to perform their own isolation and cell line establishment.
Plant-based food manufacturers often struggle with batch-to-batch ingredient inconsistency and variability between suppliers. Better analytical tools for predicting plant-based ingredient performance could improve manufacturing efficiency and create more transparent ingredient markets. Tools are needed to predict how ingredients will perform after various processing methods and in end-product applications like plant-based meat and dairy.
