Cultured Meat

Key Facts about Cultured Meat

The future of meat lies in groundbreaking lab-grown innovations, leveraging the cultured meat process to create sustainable alternatives to traditional meat production. This innovative approach involves cultivating cells in controlled environments to replicate natural meat’s texture and nutritional content — a process known as the lab-grown meat process.

As cultured meat production continues to evolve, it promises to revolutionize the food industry by offering ethical, environmentally friendly meat options without the need for animal farming.

Cultured meat — also called cultivated or lab-grown meat — is produced by expanding animal cells ex vivo in controlled bioreactor systems instead of raising and slaughtering whole animals. It combines principles from stem cell biology, tissue engineering, and bioprocess engineering to generate edible muscle and fat tissues with meat-like structure and nutritional properties.

In contrast to classical microbial fermentations or industrial mammalian processes, cultured meat bioprocesses must maintain not only high viability and productivity but also the correct differentiation state, tissue architecture, and sensory attributes — because the cells and tissues themselves become the final food product.

Media components, scaffolds, and any process additives must be compatible with food-grade standards and future regulatory frameworks for human consumption — while processes must remain scalable from milliliter-scale R&D to pilot and production volumes with reproducible texture, flavor, and nutritional quality.

Standard Process Workflow

The cultured meat process — also known as cultivated meat or artificial meat process — begins with cell extraction and follows a structured sequence through to harvest and product development.

  1. Cell selection

    Cells suitable for meat production are harvested — usually muscle stem cells which are capable of differentiating into muscle tissue and form the biological basis of cultivated meat.

  2. Cultivation and proliferation

    Selected cells are cultivated in a bioreactor with ideal conditions for growth — including temperature, oxygen, pH, and a nutrient-rich medium — promoting rapid cell proliferation. Initial expansion typically uses parallel small-scale runs in the Applikon MiniBio for media and parameter optimization, then scales up in bench- and pilot-scale glass or single-use bioreactors (e.g. Applikon BioBench, BioPilot) — operated in batch, fed-batch or perfusion mode to reach target biomass and cell densities.

  3. Differentiation

    Once high cell density is reached, differentiation takes place. Inside the bioreactor, cells develop into different muscle fiber types — the building blocks of meat.

  4. Harvesting

    Over several weeks, muscle fibers accumulate to form meat tissue. The lab-grown meat is then harvested. Batch, fed-batch, perfusion, or chemostat processes can all be applied.

  5. Post-harvest processing

    Texture, taste, and nutritional properties can be modified after harvesting — including enhancement with other cell types such as proliferated fat cells for improved product quality.

  6. Product development

    Lab-grown meat is prepared and tested for consumption, ensuring it meets safety and quality standards. Authorization procedures are in progress in various countries to define required quality standards.

Capabilities

Applikon Mini Bioreactor: The Start of a Successful Cultivation Process

The Applikon Mini Bioreactor plays a crucial role in the field of artificial meat production, particularly in the area of research and development of lab meat. It is designed to cultivate animal cells — necessary for creating lab-grown meat — through a controlled and efficient small-scale process.

This technology represents a significant advancement in producing meat without the need for traditional animal farming, aligning with sustainable and ethical food production goals. As the cells multiply, the bioreactor supplies optimum growth conditions, allowing for scale-up from a few cells to a substantial amount suitable for meat production.

Typical Cell Types Used

  • Muscle Satellite Cells / Muscle Stem Cells

    Satellite cells are tissue-resident stem cells located in skeletal muscle that can proliferate as myogenic progenitors and differentiate into myotubes and mature muscle fibers. They are lineage-committed toward muscle, which simplifies differentiation protocols — but limits long-term proliferation compared with pluripotent stem cells.

  • Mesenchymal Stem Cells (MSCs) & Fibro-Adipogenic Progenitors

    MSCs and related progenitors give rise to adipocytes, fibroblasts, and other mesenchymal lineages — attractive for generating intramuscular fat that contributes to flavor and juiciness. Compared with robust microbial hosts, these cells are more sensitive to shear stress and require gentler mixing, lower gas sparging rates, and carefully controlled microenvironments in the bioreactor.

  • Induced Pluripotent Stem Cells (iPSCs) & Embryonic Stem Cells

    Pluripotent cells offer theoretically unlimited self-renewal and can be directed toward muscle and fat lineages via stage-wise differentiation protocols. They demand very tight control over culture conditions — including growth factor concentrations and oxygen levels — to avoid unwanted differentiation or genetic instability, increasing process complexity compared with many standard bioprocess cell lines.

  • Supporting Cell Types (Endothelial Cells, Fibroblasts & Others)

    For more structured cultivated meat products, co-cultures with endothelial and stromal cells help form vascular-like networks, improve mass transfer, and support complex tissue architectures. Such co-cultures add another layer of complexity to bioreactor design and control strategies relative to single-cell-type microbial or mammalian processes.

Bioprocess Engineering

Key Process Parameters

Cultivated meat processes rely on precise control of the bioreactor environment to balance cell proliferation, viability, and differentiation. Unlike many industrial bioprocesses, every parameter directly impacts not just yield but also the sensory and structural quality of the final food product.

Applikon bioreactor systems provide the tightly controlled environment necessary to regulate temperature, pH, dissolved oxygen, and hydrodynamic conditions — all critical for preserving cell phenotype and guiding differentiation into muscle fibers and adipocytes.

FAQ - Cultured Meat

Cultured meat production typically starts with harvesting muscle stem cells from animals. These cells are capable of differentiating into muscle tissue — the primary biological component of meat. They are cultivated in a bioreactor where they proliferate and then differentiate into different muscle fiber types, which form the building blocks of lab-grown meat.

The bioreactor is the core vessel of the cultured meat process. It provides precisely controlled conditions — temperature, pH, dissolved oxygen, and nutrient supply — that allow cells to grow and differentiate as they would inside an animal. The Applikon Mini Bioreactor is particularly suited for R&D, providing optimal culture conditions at small scale, while also supporting scale-up towards production volumes.

Cultured meat production can apply different bioprocess types depending on the production stage and target product. These include batch, fed-batch, perfusion, and chemostat processes — each offering different advantages in terms of cell density, nutrient supply, and product yield. The Applikon bioreactor platform supports all of these process formats.

The cultured meat process can take several weeks from initial cell inoculation to harvest. The timeline depends on the cell type, culture conditions, and the scale of production. After harvesting, the lab-grown meat may undergo additional post-harvest processing steps to modify texture, taste, and nutritional properties before it is ready for testing and product development.

Authorization procedures for cultured meat are currently in progress in various countries to define the required quality and safety standards. The regulatory landscape is evolving as the field advances. Currently, lab-grown meat is prepared and tested to ensure it meets food safety requirements, and regulatory approvals are being sought across multiple jurisdictions to enable commercial market entry.
