For decades, tissue engineering has relied on synthetic polymers, ceramics, and animal-derived collagen to support healing after injury. But these materials come with trade-offs: high costs, complex manufacturing, and inconsistent biological outcomes. As the demand grows for sustainable, patient-friendly solutions, researchers are turning to an unlikely source—fungi.
Mycelium, the root-like network of fungi, is now being explored as a biocompatible, biodegradable scaffold for tissue repair. Cultivated on agricultural waste and shaped with minimal processing, these natural structures offer a promising alternative to conventional medical scaffolds.
Mycelium: Nature’s Self-Assembling Scaffold
Fungi grow by extending thread-like cells called hyphae, which weave together into dense, porous networks known as mycelium. In nature, these networks help decompose organic matter and interact with plant roots. In the lab, they can be harnessed to form scaffolds—3D frameworks that guide cells to grow, divide, and form new tissues.
Once sterilised, mycelium scaffolds offer structural support while degrading gradually as healthy tissue forms. Their natural components, like chitin and β-glucans, are known to promote healing and modulate immune responses.
Comparing the Field: Traditional vs. Mycelium-Based Scaffolds
Traditional scaffolds made from collagen, synthetic polymers (like PLGA or PCL), or ceramics have shaped the field of regenerative medicine for years. They offer customisable mechanical properties and a robust track record of clinical use. But they also come with limitations: animal-based materials carry immune risks and high variability; synthetic materials often require surface modifications to support cell growth.
Mycelium scaffolds, by contrast, grow themselves. Fungi can be cultivated on cheap, renewable substrates such as sawdust or straw, and shaped into tailored geometries through moulding or 3D printing. These scaffolds are innately porous, bioactive, and biodegradable.
"You're growing the structure, not building it from parts," says Manaal Lakhani, whose recent review compares these platforms in detail. "It’s bottom-up manufacturing guided by biology."
Promising Applications
Mycelium scaffolds have already shown early success in:
Wound healing: Mycelium-based dressings accelerate healing in skin wounds by maintaining moisture and encouraging cell migration.
Bone regeneration: When mineralised with calcium phosphate, mycelium supports osteoblast attachment and bone tissue formation.
Soft tissue repair: Flexible sheets of mycelium could be adapted for muscle, tendon, or even organ regeneration when reinforced.
Drug delivery: Their porous structure allows loading with antibiotics, growth factors, or anti-inflammatory agents, releasing them as the scaffold degrades.
Challenges Remain
Despite their promise, fungal scaffolds face technical and regulatory barriers:
Scalability: Small changes in growth conditions—humidity, temperature, substrate—can affect structure, making consistent manufacturing a challenge.
Mechanical strength: Mycelium suits soft tissue well but often needs reinforcement for load-bearing applications.
Regulatory uncertainty: With no precedent for fungi-based implants, approval pathways remain undefined.
Researchers are addressing these issues through composite design (e.g., combining mycelium with ceramics or silks), genetic engineering of fungal strains, and the development of bioreactor-based growth systems.
Rethinking Biofabrication
One emerging vision is to grow scaffolds on demand. Clinics could one day cultivate patient-specific implants using local fungal cultures shaped to CT-scan data. This would shorten supply chains, lower costs, and reduce environmental impact.
Mycelium’s sustainability credentials are strong: it grows on waste, requires little energy, and leaves no harmful residues. As medicine grapples with the ecological cost of care, mycelium offers a pathway to greener solutions.
What's Next?
To bring fungal scaffolds to the clinic, researchers must:
Establish consistent, standardised production protocols
Conduct long-term safety and immunogenicity studies
Demonstrate efficacy across a range of tissue types in large animal models
Engage regulators to define clear approval pathways
Mycelium scaffolds are not yet ready to replace conventional materials outright. But as their capabilities grow—and clinical evidence mounts—they may offer a safer, cheaper, and more sustainable option for tissue regeneration.
With ongoing work at the intersection of mycology, bioengineering, and regenerative medicine, the future of healing definitely has the potential of being transformed by fungi.
