1. Collagen
Collagen is a popular choice for cultivated meat scaffolds. As the most abundant protein in animal tissues, it naturally forms the structural backbone of muscles, making it ideal for replicating the texture of meat in a lab setting.
Biocompatibility
One of collagen's standout features is its excellent compatibility with biological systems. As a key component of the extracellular matrix (ECM) in animal tissues, it provides natural binding sites that encourage cell adhesion, growth, and development [1][5]. Its low tendency to trigger immune responses further strengthens its appeal for use in cultivated meat [3].
However, while collagen supports cell growth effectively, its physical durability often needs improvement.
Mechanical Strength
Collagen's strength is moderate, which means it sometimes requires reinforcement. Pure collagen scaffolds can support basic muscle tissue formation but are generally softer than synthetic materials like PCL [5]. A 2024 study demonstrated that combining 4% collagen with 30 U/g transglutaminase in an aligned porous scaffold boosted mechanical strength while promoting the growth and differentiation of porcine skeletal muscle satellite cells [3]. This example shows how combining collagen with other elements can address its weaknesses without compromising its biological advantages.
Strength aside, how collagen degrades is equally important.
Degradation Profile
Collagen's ability to break down naturally is a significant advantage for edible scaffolds. Cells can enzymatically degrade the material as the tissue matures, ensuring the scaffold is gradually absorbed [1]. This controlled breakdown guarantees that the final cultivated meat product is free from non-degradable residues, making it safe to consume.
Scalability
Scaling up collagen production presents some hurdles. Traditional animal-derived collagen faces ethical concerns and supply chain issues, which can conflict with the sustainability goals of cultivated meat. Recombinant collagen - produced using plants or microbes - offers an animal-free alternative that addresses these challenges [1][5]. Though currently more expensive, advances in technology are improving consistency and driving down costs.
Cellbase connects industry professionals with suppliers of both traditional and recombinant collagen designed specifically for cultivated meat applications.
2. Gelatin
Gelatin is a common biomaterial used for scaffolding, derived from collagen through hydrolysis. This natural biopolymer is well-known for its safety in food applications and its effectiveness in providing structural support.
Biocompatibility
One of gelatin’s key strengths is its high biocompatibility. It closely mimics the extracellular matrix, creating an environment where muscle and fat cells can attach, grow, and differentiate efficiently [1]. Its widespread use in products like jellies and capsules underscores its safety and regulatory approval, making it a reliable choice for cultivated meat production.
Mechanical Strength
While pure gelatin offers moderate mechanical strength, this can be enhanced by adjusting its concentration, crosslinking, or blending it with materials like alginate or plant proteins [2][5]. Research shows that gelatin coatings improve water absorption, strengthen the scaffold, and promote better cell attachment [3]. For instance, composite scaffolds combining textured vegetable protein with gelatin and agar (at 6% concentration) have demonstrated improved structural integrity and functionality [3].
Degradation Profile
Gelatin’s controlled biodegradation is another advantage, as it breaks down enzymatically during cell culture. This gradual degradation supports tissue maturation while ensuring the scaffold material is removed in a controlled manner [1]. By tweaking crosslinking or blending it with other substances, the degradation rate can be fine-tuned to match the needs of specific cell growth phases, leaving no unwanted residues in the final product.
Scalability
Gelatin is well-suited for large-scale cultivated meat production. It’s affordable, readily available in bulk, and compatible with industrial processes like freeze-drying and 3D bioprinting [1][6]. While traditional gelatin is animal-derived, there’s growing interest in recombinant or plant-based alternatives to address ethical concerns.
UK-based producers can benefit from suppliers like Cellbase, which offers verified gelatin tailored for cultivated meat applications. These suppliers ensure compliance with food safety standards and industry needs, making gelatin a versatile and practical option as scaffold technologies continue to advance.
3. Alginate
Alginate, a polysaccharide derived from brown seaweed, stands out as a plant-based option for creating scaffolds in cultivated meat production. Its long history of safe use in food makes it a reliable choice for supporting cell growth in this emerging field.
Biocompatibility
Alginate is well-suited for growing muscle and fat cells due to its compatibility with biological systems. It has been approved for food use by regulatory bodies in the UK and EU, simplifying the approval process for cultivated meat applications. While native alginate doesn't naturally support cell adhesion, this can be addressed by incorporating adhesion peptides or mixing it with other materials like gelatin [1].
Mechanical Strength
One of alginate's strengths is its adjustable mechanical properties, which allow producers to fine-tune scaffold stiffness to mimic the texture of real meat. Studies have shown that combining alginate with other biomaterials can significantly improve its performance. For instance, a 2022 study highlighted how blending alginate with pea protein isolate in a 1:1 ratio enhanced its mechanical properties, such as Young's modulus, porosity, and liquid uptake. This blend also supported the growth and differentiation of bovine satellite cells [3]. While pure alginate gels can be prone to brittleness, these composite approaches help address that limitation.
The ability to customise its mechanical properties also makes alginate ideal for achieving the desired degradation profile.
Degradation Profile
Alginate's biodegradability and edibility make it a perfect match for cultivated meat. It safely breaks down in the human digestive system, ensuring the final product is entirely consumable. By tweaking its crosslinking and composition, producers can control how it degrades. Typically, ionic crosslinking with calcium chloride is used to create stable hydrogels that are well-suited for muscle cell culture [1].
This controlled degradation ensures alginate can meet the demands of large-scale production.
Scalability
Alginate's abundance and affordability make it an attractive choice for commercial-scale cultivated meat production. It benefits from established supply chains within the seaweed industry, and its gelation properties align well with automated manufacturing techniques like extrusion and 3D bioprinting. In the UK, producers can access high-quality, food-grade alginate through platforms like Cellbase, which specialise in materials tailored for cultivated meat applications.
4. Chitosan
Chitosan offers an interesting non-mammalian option for cultivated meat scaffolds, with surface properties that set it apart. Derived from chitin, found in crustacean shells and fungi, this biopolymer is particularly effective at supporting cell attachment and growth due to its cationic nature, which interacts well with negatively charged cell membranes.
Biocompatibility
Chitosan is highly compatible with various cell types critical to cultivated meat production. It promotes the adhesion, proliferation, and differentiation of cells such as porcine skeletal muscle satellite cells, rabbit smooth muscle cells, sheep fibroblasts, and bovine umbilical cord mesenchymal stem cells [7].
Interestingly, chitosan mimics natural glycosaminoglycans, creating an environment conducive to cell growth. A 2022 study found that microcarriers containing 2% chitosan and 1% collagen (in a 9:1 ratio) significantly improved cell viability and proliferation across multiple cell types [3]. This blended approach compensates for chitosan's limited cell-binding capabilities when used on its own.
Another advantage is its antimicrobial properties, which help minimise contamination risks during production - an essential factor for maintaining sterile conditions in commercial facilities [3].
Mechanical Strength
While chitosan alone has weak mechanical properties, these can be enhanced by combining it with other biomaterials [7]. For instance, blending with collagen improves its compressive strength and allows for the creation of porous structures that better replicate the texture and mechanical properties of meat. These composites also support the proliferation and differentiation of porcine skeletal muscle satellite cells [7].
The use of crosslinking agents or complementary materials like collagen or transglutaminase further boosts chitosan's resilience, making it more suitable for supporting tissue formation [7].
Degradation Profile
Chitosan's biodegradable nature makes it an excellent choice for edible scaffolds. It naturally breaks down through enzymatic processes, ensuring the final product remains fully consumable.
Producers can adjust the degradation rate by modifying factors like the degree of deacetylation or crosslinking. This allows for controlled breakdown that aligns with tissue growth and maturation timelines [7]. Such flexibility ensures that chitosan matches the performance of other scaffold biomaterials while remaining safe and edible.
Scalability
Beyond its biological and mechanical benefits, chitosan is highly scalable, which is vital for commercial cultivated meat production. It is abundant and relatively inexpensive, especially when sourced from fungal fermentation or seafood industry by-products [7].
However, ensuring consistent quality and mechanical performance at an industrial scale requires standardised processing and careful blending with other biomaterials [7]. In the UK, producers can turn to platforms like Cellbase for high-quality chitosan tailored to cultivated meat production needs.
Its status as an edible material and inclusion in FDA-approved biomaterials also simplifies regulatory approval, making it a practical choice for large-scale applications [2].

5. Plant-Derived Proteins (Soy Protein and Textured Vegetable Protein)
Plant-based proteins, particularly soy protein and textured vegetable protein (TVP), provide a practical, animal-free alternative for creating scaffolds in cultivated meat production. These materials not only reduce environmental impact but also offer cost-effective solutions for scaling up production.
Biocompatibility
Soy protein scaffolds have shown strong compatibility with the cell types commonly used in cultivated meat. Thanks to their surface chemistry and customisable porosity, they support essential processes like cell adhesion, growth, and differentiation - all without relying on animal-derived components [1][8]. Studies even highlight the successful use of textured soy protein scaffolds in cultivating bovine muscle tissue, achieving notable results in cell attachment and tissue formation [1][8].
TVP, on the other hand, brings a fibrous structure to the table, mimicking the texture of traditional meat while retaining the biocompatibility needed for cell culture. Its porous structure can be fine-tuned during production to improve cell infiltration and nutrient distribution throughout the tissue [1].
Mechanical Strength
These plant-derived proteins also offer adjustable mechanical properties, which are crucial for supporting tissue growth. Research indicates that combining soybean protein isolate with dietary fibre, glycerol, and crosslinkers enhances both compression strength and water resistance [3].
Glycerol, a common plasticiser, plays a key role in improving scaffold performance. Findings from 2024 show that soy protein scaffolds with higher glycerin content form smaller, more uniform pores, leading to better water resistance and mechanical durability [3]. Production methods like freeze-drying, extrusion, and 3D printing allow manufacturers to fine-tune elasticity and tensile strength, creating scaffolds that can replicate the complex textures of meat [1][2].
However, while mechanical strength is critical, the scaffolds must degrade in sync with the tissue's growth and maturation.
Degradation Profile
Both soy protein and TVP are naturally biodegradable and safe for consumption. Their degradation rates can be adjusted by modifying protein composition and crosslinking techniques, ensuring the scaffolds provide structural support during cell growth and break down appropriately as the tissue matures [1].
Beyond structural benefits, these scaffolds add nutritional value to the final product, making them a dual-purpose solution [1].
Scalability
Plant-derived proteins strike a balance between performance and scalability, with scaffolding materials accounting for only around 5% of the total production cost for cultivated meat [1]. Soy protein, in particular, benefits from its widespread availability and established supply chains, making it well-suited for large-scale operations.
Industrial techniques like extrusion, freeze-drying, and 3D printing allow for the mass production of consistent, high-quality scaffolds [6]. However, scaling up does come with challenges, such as ensuring uniform scaffold properties and integrating large-scale fabrication with cell culture processes [6].
In the UK, platforms like Cellbase simplify access to plant-derived scaffolding materials. They connect producers with verified suppliers, offering transparent pricing and expert guidance tailored to the needs of cultivated meat production. This streamlined procurement process supports both research teams and commercial operations, ensuring reliable access to quality materials for scaling up production.
6. Decellularized Plant Leaves
Decellularized plant leaves provide a natural framework that leverages the intricate vascular systems already present in plants. By stripping plant tissues of their cellular material, researchers are left with a cellulose-based extracellular matrix. This structure is remarkably similar to the capillary networks found in animal tissues, making it an excellent choice for cultivated meat production, where efficient nutrient delivery and organised cell growth are essential.
Biocompatibility
The cellulose matrix in decellularized plant leaves works seamlessly with the muscle and fat cells used in cultivated meat. Studies have shown that bovine muscle cells can attach and grow effectively on decellularized spinach leaves. The fibrous structure supports key cellular functions such as adhesion, growth, and differentiation [1][8].
A major advantage of these scaffolds is their completely plant-based composition. This eliminates risks associated with animal-derived materials, such as immune reactions or contamination, and aligns with the ethical motivations behind cultivated meat production.
In addition, the natural vascular networks within plant leaves provide an ideal pathway for transporting nutrients and oxygen to growing cells. This closely mirrors the capillary systems found in traditional meat, making it easier to develop tissue with the right structure [1].
Mechanical Strength
From a structural perspective, the performance of these scaffolds depends on their cellulose content and vascular architecture. While they may not be as strong as synthetic alternatives, they offer sufficient support for cell growth and tissue development in cultivated meat applications [1].
The fibrous design can also be adjusted to replicate different meat textures, contributing to both the structural quality and the mouthfeel of the final product. However, the mechanical properties can vary depending on the type of plant used and the specific decellularisation process applied.
Research highlights that the vein networks in plant leaves provide enough mechanical support for muscle cell growth while maintaining the flexibility required for tissue development [1].
Degradation Profile
Another key feature of these scaffolds is their controlled breakdown during tissue growth. Decellularized plant leaves degrade at a pace that aligns with the timeline of cultivated meat production. The cellulose-based structure is not only biodegradable but also edible, adding dietary fibre to the final product instead of leaving harmful residues [1].
Although cellulose cannot be digested by human enzymes, it is considered safe to eat and can even enhance the nutritional profile of cultivated meat. The rate at which the scaffold degrades can be adjusted by modifying processing methods or incorporating other plant-based compounds. This allows producers to synchronise scaffold breakdown with the tissue's development [1].
This gradual degradation ensures that the scaffold remains supportive during critical growth stages, then dissolves as the tissue becomes self-sustaining.
Scalability
Decellularized plant leaves also present a practical and economical option for scaling up cultivated meat production. Their abundance, low cost, and renewable nature make them highly suitable for commercial use. Spinach leaves, for example, have been extensively studied and are a popular choice for this purpose [1][6].
Techniques such as immersion decellularisation and solvent casting are straightforward and can be adapted for large-scale manufacturing. With scaffolding materials accounting for just about 5% of total production costs, they help improve the economic feasibility of cultivated meat production [1].
For producers in the UK, platforms like Cellbase simplify the process of sourcing decellularized plant leaf scaffolds. These platforms offer curated listings with clear pricing in pounds sterling, ensuring that research teams and commercial operations have reliable access to high-quality materials that meet the technical demands of cultivated meat production.
7. Microbial and Algae-Derived Biomaterials
Microbial and algae-derived biomaterials are paving the way for more sustainable scaffolds in cultivated meat production. Derived from sources like bacteria, yeast, fungi, and algae, these materials offer a completely animal-free alternative while still meeting the functional demands of tissue development. Companies in the field are actively working on materials such as bacterial cellulose, fungal mycelium, and algae-based scaffolds to support this growing industry [4].
What makes these biomaterials so appealing? Their ability to be eaten, their adjustable properties, and their renewable nature are key. For example, bacterial cellulose, fungal mycelium, and alginate from brown algae can be tailored to specific needs, aligning perfectly with the ethical goals of producing meat without animals [1][2]. These materials not only complement traditional scaffolds but also provide a renewable and customisable alternative for cultivated meat production.
Biocompatibility
Bacterial cellulose stands out for its compatibility with animal cells used in cultivated meat. Its nanofibrous structure closely resembles the natural extracellular matrix, promoting strong cell adhesion and tissue growth. Studies have shown successful cultivation of bovine and fish muscle cells on bacterial cellulose scaffolds, achieving promising tissue structures with excellent cell viability [1][2][8].
Algal alginate is another strong contender, offering gentle gelation properties and non-toxic characteristics. It supports essential cell functions - like attachment, growth, and differentiation - making it ideal for encapsulating muscle and fat cells during cultivation [1][2].
Fungal mycelium, while requiring some engineering to enhance cell attachment, provides a naturally fibrous base for muscle cell development. Surface modifications can further improve its compatibility with cultivated cells [1][2].
Mechanical Strength
The mechanical properties of these biomaterials vary, making them adaptable to different uses. Bacterial cellulose, for instance, forms strong yet flexible films with adjustable stiffness. Processing techniques and changes in cross-linking density allow manufacturers to fine-tune its properties to meet specific product needs [1][2].
Alginate hydrogels, on the other hand, offer a softer option. While naturally more pliable than bacterial cellulose, their firmness can be enhanced through careful formulation and processing [1][2].
Fungal mycelium provides a spongy, fibrous structure that mimics meat textures. However, achieving the elasticity and tensile strength of natural muscle tissue often requires combining mycelium with other biomaterials or additional engineering [1][2].
Algae-based scaffolds can also be designed with porous, layered structures that closely resemble animal tissue. With pore sizes between 50 and 250 μm, they create an ideal environment for muscle cell infiltration and tissue formation [9][10].
Degradation Profile
The degradation rates of these materials are well-suited to the timelines required for cultivated meat production. While mechanical properties can be adjusted during processing, their degradation profiles can also be tailored to match tissue growth.
Bacterial cellulose degrades slowly, offering long-term support, whereas alginate breaks down more quickly and can be controlled to fit different cultivation schedules [1][2].
Fungal mycelium has moderate degradation rates, which can be adjusted based on its composition and processing techniques. Combining it with other materials or modifying its structure allows further control over its breakdown [1][2].
Scalability
One of the biggest advantages of microbial and algae-derived biomaterials is their scalability. Bacterial cellulose, for example, can be mass-produced through fermentation using low-cost feedstocks, making it an economical choice for commercial meat production [1][2][6].
Algal alginate benefits from an already established manufacturing infrastructure, as it is widely used in the food and pharmaceutical industries. This existing supply chain makes it easier to integrate into cultivated meat production [1][2][6].
Fungal mycelium also shows great potential for scaling up. It can be grown quickly on agricultural by-products, reducing costs and supporting sustainability by repurposing waste materials [1][2][6].
Given that scaffolding materials account for about 5% of total production costs, these economical options significantly enhance the financial viability of cultivated meat. For UK-based researchers and businesses, platforms like Cellbase simplify access to these advanced materials. They offer transparent pricing in pounds sterling and connect buyers with trusted suppliers specialising in microbial and algae-derived scaffolds tailored for cultivated meat applications.
