3D Printed Silk Bio-ink for Bone Marrow Modeling and Drug Testing

healthTestedTRL 5

Imagine trying to grow fragile blood-forming cells in a lab, but they keep dying because the surface is too rough. This project creates a special 'ink' made from silk that acts like a soft, protective cushion, mimicking the natural environment of human bone marrow. It allows scientists to 3D print a realistic miniature version of bone marrow to test new medicines without needing animal trials.

The business problem

What needed solving

Current in vitro models cannot accurately replicate the soft tissue environment of human bone marrow, making it difficult to culture fragile stem cells. This limits the effectiveness of drug development and personalized medicine for hematological diseases.

The solution

What was built

A silk-based bioink optimized for 3D bioprinting with specific viscosity and stiffness to support the viability and differentiation of hematopoietic stem cells.

Who can put this to work

Pharmaceuticals
enterprise
Target: Drug Discovery Firm

If you are a drug discovery firm dealing with high failure rates in animal testing for blood diseases — this project developed a silk-based bioink that enables high-throughput drug discovery using human-specific models. This reduces the reliance on animals and improves the accuracy of early-stage testing.

Biotechnology
SME
Target: Personalized Medicine Clinic

If you are a clinic dealing with patients suffering from chemotherapy-induced bone marrow failure — this project developed a 3D printing platform that uses minimal cells from patients to screen for the most effective treatments. This allows for tailored therapy based on the patient's own biological response.

Medical Device Manufacturing
mid-size
Target: Bioprinting Hardware Provider

If you are a bioprinting hardware provider dealing with a lack of specialized materials for hematological research — this project developed a validated silk bioink with optimized viscosity and stiffness. This expands the range of compatible biological tissues your machines can produce.

Frequently asked

Quick answers

What is the cost or pricing model for SILKink?

Based on available project data, specific pricing is not mentioned, but the project aims to found an investment-ready spin-off company to commercialize the product.

Can this be produced at an industrial scale?

The project involves CELLINK, a partner responsible for product development, and focuses on creating standardized printing protocols to ensure high repeatability and fidelity.

Who owns the IP and how is licensing handled?

The University of Pavia and CELLINK co-own the background IP developed during the previous SilkFUSION project.

How does this integrate into existing lab workflows?

The bioink is designed for 3D bioprinting, allowing researchers to create models in the specific shape or volume desired for their experiments.

What is the timeline for market availability?

The project runs from June 2023 to May 2026, with the goal of creating an investment-ready spin-off by the end of the period.

Consortium

Who built it

The consortium is highly commercially oriented, with a 75% industry ratio consisting of 3 industrial partners (including 2 SMEs) and 1 university. The presence of CELLINK for product development and Catalyze-Group for venture building indicates a strong push toward market entry and the creation of a spin-off company.
