Scaling Natural Cell Manufacturing

VitelleX is a biotech venture pioneering the development of stem cell-derived, bioengineered models for scalable production of specific cell types. Our proprietary platform open new pathways toward universal, ethically-sourced and clinically applicable alternatives to donor-derived materials.

VitelleX mission

VitelleX applies the principles of early human development to industrialize human tissue production without relying on donors or classical cell culture. These new multicellular systems have the potential to give rise to various stable and expandable cell types, which are currently in short supply, and to serve as a game changer in the field of Regenerative Medicine. The goal is to make cell manufacturing safer, more scalable, and more accessible than current culturing technologies.

“VitelleX represents a next-generation approach to regenerative medicine,” says Prof. Dr. Clemens van Blitterswijk, co-founder and professor at the MERLN Institute. “We’re building an entire platform that makes complex cell technologies scalable and ready for real-world use.” Co-founder and CSO Dr. Erik Vrij adds: “Our platform allows us to grow cells in a controlled 3D environment. It’s not just about making cells; it’s about making reliable systems that can work at scale.” Prof. Dr. Stefan Giselbrecht, also co-founder, continues: “What excites me is the shift from one-off scientific discoveries to generic cell-based platforms that can power many future therapies. This is how regenerative medicine becomes a real, scalable solution.”

Building on its international reputation, Maastricht University (UM) is a driver of groundbreaking, cross-disciplinary research. Organized around four core themes—Quality of Life, Learning and Innovation, Europe and a Globalising World, and Sustainability and Circularity—UM addresses complex societal challenges and translates knowledge into real-world solutions.

Our goal

In the coming years, VitelleX will focus on testing and refining its technology platform, improving efficiency, reproducibility, and readiness for clinical application. VitelleX operates as a focused innovation venture, with research and development carried out by ReGEN Biomedical. The company works closely with academic and industry partners to bring promising technologies toward medical application.

Over the past years, the Weijerhorst foundation supported this research with a generous donation towards research in tissue engineering and regenerative biology. Weijerhorst is following up on this through investments via its subsidiary Particon. Together with Brightlands Life Sciences Ventures, they are making it possible for VitelleX to test and improve the new method, in order to bring this science one step closer to benefiting society and patients.

Prof. Dr. Clemens van Blitterswijk

Founder & Scientific Advisory. In the early 1990s, Prof. Clemens van Blitterswijk was one of a small group of scientists worldwide who was beginning to realize that biomaterials could be used to induce the body’s cells to heal damaged tissues. These discoveries formed the basis for a new field called tissue engineering, which aims to replace or regenerate diseased or damaged tissues through a combination of biology and engineering. Van Blitterswijk is widely considered to be the founder of tissue engineering in Europe.
