A defined and long-term 3D organoid culture with Biosilk and Biolaminin®
Biosilk + Biolaminin provide a stable, biorelevant microfiber system that supports reproducible organoid growth, improved differentiation, and long-term viability
Biosilk and Biolaminin microfiber networks generate tissue-specific 3D microenvironment
The combination of Biosilk and Biolaminin delivers a highly controlled 3D microenvironment that reduces batch‐to‐batch and intra-culture variation, supports long-term differentiation protocols, provides physiologically relevant cell–matrix and cell–cell interactions, and enables the generation of organoid models with improved organization and functional maturity. It therefore provides a robust platform for disease modelling, drug discovery, regenerative medicine, and advanced cell-therapy applications.
Key Advantages for Biosilk and Biolaminin
Biorelevant 3D microenvironment
Combining Biosilk with tissue-specific Biolaminin creates a defined network that closely mimics the natural cellular niche, supporting optimal attachment, survival, and lineage-specific differentiation.
Long-term culture support
The microfiber network enables efficient nutrient and oxygen diffusion, allowing long-term growth and maturation of organoids without compromising cell viability.
Defined and animal-origin free
Chemically defined, recombinant, biodegradable, and non-immunogenic, Biosilk and Biolaminin are animal-origin free, providing a consistent matrix for research and translational applications.
Reduced variability
Biosilk and Biolaminin promote uniform cell integration and organization, reducing batch-to-batch and intra-organoid variation compared with conventional organoid systems.
No necrotic cores
Enhanced diffusion and 3D architecture prevent formation of necrotic centers, even in large organoids, supporting healthier, fully functional tissue models.
Versatile and easy to use
Biosilk self-assembles into microfibers networks without special equipment, supporting diverse cell types, organoid formats, and long-term differentiation protocols.
