A review published on 3 October examines why those capabilities do not automatically translate into an affordable, structured food product. Long-term cell performance, culture media, scaffolds and bioprocessing have to work together. The authors conducted a structured literature search across PubMed, Scopus and Web of Science, with the final search in August 2026. The result is a narrative synthesis, not a formal systematic review with a study-quality or risk-of-bias assessment. It brings together development strategies and limitations; it does not demonstrate a new commercial process or establish a universal cost reduction. ## Expansion and differentiation need different conditions A cell population has to expand sufficiently while retaining the ability to form muscle tissue. Extended culture can change that balance, so selection and monitoring of cells are central to consistency. A high cell count alone cannot establish that the resulting material will develop the desired structure or perform reliably over successive production cycles. Media requirements also vary between species, cell types and production stages. Conditions that maintain proliferating cells are not necessarily suitable for differentiation into muscle structures. The review therefore emphasises stage-specific optimisation, including serum-free approaches, rather than transferring a formulation from another cell system and assuming it will serve the entire cultured-meat process. ## Food-compatible inputs and useful scaffolds Culture-media design must consider more than laboratory growth performance. Components such as growth factors, hormones and other additives need assessment for their intended food-production use, alongside their cost and consistency. The review discusses computational and AI-assisted approaches as ways to guide ingredient selection and optimisation, with experimental confirmation still required. Scaffolds introduce a parallel set of requirements. They must support cell attachment and tissue organisation while remaining compatible with the intended product and manufacturing process. A material useful in biomedical tissue engineering is not automatically a practical food ingredient. Scaling the system therefore connects biological function with handling, process control and the characteristics expected in the finished food. ## Safety and economics belong in the same development plan The review identifies potential biological, chemical and physical hazards across sourcing, expansion, harvesting and formulation. It also makes a useful distinction: genetic or phenotypic changes during culture do not automatically constitute a food-safety hazard. Their relevance has to be evaluated in the context of the cells, the process and the final product rather than assumed from their presence alone. The authors call for integrated work on productivity, reproducibility, product-specific safety and economic feasibility. Environmental advantages are likewise conditional on the production scenario, not guaranteed by the cultured-meat label. For developers and equipment suppliers, the paper provides a connected research agenda: optimise cells, media, structure and process together, then demonstrate that the combined system meets the requirements of the food it is intended to produce. ## Sources and rights - [MuSC cultivation for cultured meat production: recent advances, current limitations, and future directions.](https://europepmc.org/articles/PMC13634025?utm_source=foodradar.org&utm_medium=referral&utm_campaign=editorial&utm_content=cultured-meat-muscle-stem-cells-media-scale-up-en).
