What Is Nidogen-1, the Molecular Guide of Skin Regeneration?
Nidogen-1 is our patented ingredient. ChaMeditech holds the global patent for the efficacy of recombinant Nidogen-1. No other exosome-based product in the world offers this added benefit. Its inclusion helps optimise and support superior collagen synthesis, making it a standout advancement in skin regeneration and tissue engineering.
Definition & Biological Role
Nidogen-1, also known as entactin, is a structural protein found in the extracellular matrix (ECM), the intricate network that surrounds and supports cells within tissues. Think of it as the molecular glue that holds the ECM together.
Nidogen-1 forms critical connections between laminin, collagen type IV, and Perlecan, three primary components of the basement membrane and the dermal-epidermal junction (DEJ). By linking these structural proteins, Nidogen-1 helps maintain the integrity, resilience, and function of skin tissue.
Its key biological roles include:
- Cell adhesion – helping cells anchor in place.
- Cell differentiation – guiding cells to take on specialised roles.
- Tissue repair and regeneration – supporting healing and structural renewal
The Dermal-Epidermal Junction (DEJ)
The DEJ is the specialised boundary layer that connects the epidermis (outer skin) to the dermis beneath. Simply put, it acts as the skin’s adhesive layer, keeping the epidermis stably attached while supporting communication and repair.
Structure of the DEJ
- Lamina lucida – lies directly beneath epidermal basal cells; contains links between cells and ECM proteins like laminin.
- Lamina densa – composed of collagen IV, nidogen-1, and perlecan; provides strength and stability.
- Sub-lamina densa – on the dermal side; contains collagen VII anchoring fibrils that firmly connect epidermis to dermis.
Key Proteins of the DEJ
- Laminin – promotes cell adhesion and signalling.
- Collagen IV – provides a supportive scaffold.
- Perlecan – binds growth factors and regulates cell behaviour.
- Nidogen-1 (Entactin) – acts as the molecular adhesive, linking laminin and collagen IV and ensuring structural cohesion.
Functions of the DEJ
- Maintains skin stability by anchoring epidermis to dermis
- Regulates cell signalling, growth, and migration
- Acts as a protective barrier and supports wound healing
- Maintains elasticity; DEJ weakening is linked to sagging and wrinkle formation.
Clinical & Cosmetic Relevance
- Ageing – thinning of the DEJ contributes to skin laxity and wrinkles.
- Cosmetic interventions, such as peptides, boosters, or ECM-supporting ingredients, can strengthen the DEJ, restoring firmness and elasticity.
How Is Nidogen-1 Made?
Nidogen-1 is produced using advanced recombinant technology, a laboratory-based process that allows for safe, consistent, and controlled production. This ensures Nidogen-1 is manufactured under highly regulated conditions, resulting in a purified, bioidentical protein aligned with native Nidogen-1.
The process delivers:
- Consistent high-yield manufacturing
- Precision in structure and function
- High-purity output, suitable for advanced cosmetic and biomedical applications
The outcome is a stable, high-performance ingredient that maintains functionality and quality across every batch, without reliance on human or animal derivatives. Rigorous purification and quality testing further ensure purity levels of ≥90%, meeting elite performance standards.
Key Advantages
- Produced using advanced recombinant methods
- High purity (≥90%) for consistent performance
- Scalable, high-yield batches (e.g., >10g per 200L)
- Suitable for dermatological and regenerative applications
- Optimises collagen synthesis – a unique and exclusive feature not found in any other exosome-based product globally
Applications of Nidogen-1
Thanks to its pivotal role in ECM stabilisation and DEJ support, Nidogen-1 is an ideal active in:
- Skin Rejuvenation & Firming – supports dermal structure and elasticity
- Wound Healing & Scar Management – promotes tissue repair and regeneration
- Stem Cell Culture & 3D Tissue Engineering – enhances scaffold environments and cellular behaviour in advanced research
