BSF Enterprise Pioneering the Future of Bio-Sustainability
Turning pioneering biotechnology into focused commercial businesses
BSF Enterprise is a life sciences platform. 3D Bio-Tissues develops and owns the Group’s core technology, and our companies take it to market.
A welcome from our CEO
Dr Che Connon
Chief Executive Officer, BSF Enterprise PLC
Welcome to BSF Enterprise’s investor website, and thank you for your interest in what we are building.
Our aim is to grow high-quality tissue and materials from cells, as an alternative to sources that today depend on animals or human donors.
At the heart of the Group is 3D Bio-Tissues, our research and IP company in Newcastle upon Tyne. Its tissue-engineering platform uses macromolecular crowding to help cells lay down their own natural matrix.
From that platform, our companies are taking the technology into several markets: leather for luxury fashion and automotive interiors through Lab-Grown Leather, corneal repair through Kerato, and cell-culture media supplements through milieu.bio. ETSYL®, our collagen-stimulating peptide, is licensed for skincare. 3D Bio-Tissues has also filed a patent application for seamless tissue coverings for humanoid robot hands.
This site is built for our shareholders and anyone considering investing. You can read every announcement, watch updates from the team and ask questions on any piece of news. Please do send yours. My team and I read them all and will reply wherever we can.
BSF expands into humanoid robotics
3D Bio-Tissues has filed a priority patent application (GB2622781.9) for moulding tissue into a single, seamless 3D piece, including coverings for humanoid robot hands. It is the same stitchless architecture already in partner-funded evaluation programmes with two leading luxury fashion houses through Lab-Grown Leather.
- One continuous covering, with no glued seams to fail
- Footwear-grade wear resistance over the finger pads, thinning to 0.3 mm over the joints
- To be developed with robotics manufacturers through partner-funded agreements
Design concept from patent application GB2622781.9

US patent allowance for macromolecular crowding technology
The USPTO has issued a Notice of Allowance for US Patent Application No. 18/578,286, "Cell culture medium and supplements for corneal and skin cell culture," held by 3D Bio-Tissues. All 17 examined claims have been allowed, covering serum-free and reduced-serum media formulations that use 3D Bio-Tissues’ proprietary macromolecular crowding agents.
On issuance, the patent will protect the technology behind CityMix® and CytoBoost™, which milieu.bio sells under licence from 3D Bio-Tissues. The claims also cover the skin cell culture and matrix deposition used in Lab-Grown Leather’s production route, and support long-term cell-based options for Kerato.

US patent allowance for ETSYL® technology
The USPTO has issued a Notice of Allowance for US Patent Application No. 17/782,948, "Collagen Production," held by 3D Bio-Tissues. The allowed claims cover methods using ETSYL® (palmitoyl pentapeptide-87) to stimulate and enhance collagen production in cells.
On issuance, the patent will strengthen 3D Bio-Tissues’ IP position in the United States, a major market for anti-ageing skincare and bioactive peptides. It supports the worldwide exclusive commercialisation agreement with SCHAKAU for ETSYL® in cosmetics and luxury beauty.

Exploring cell-grown skin for robots
Robots are getting smarter and more agile, but they still meet the world through their outer surface. 3D Bio-Tissues is exploring whether its cell-grown tissue could give robot makers an alternative to the synthetic coverings they use today.
Today
Synthetic elastomers
Silicones, polyurethanes and synthetic rubbers cover most humanoid and autonomous robots. In continuous use they can wear and degrade, especially at the joints.
What we are exploring
Cell-grown tissue
3DBT’s platform grows tissue from cells, which lay down their own natural matrix. The research question is whether its natural flexibility can hold up better where synthetic coverings are under most strain.
