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.”

Maastricht University
https://www.maastrichtuniversity.nl/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.

Dr. Erik Vrij
Scientific Director & Founder. Dr. Erik Vrij is an Assistant Professor at the Department of Obstetrics and Gynecology at Maastricht University’s GROW Research Institute for Oncology and Reproduction, with a close affiliation to the MERLN institute. He obtained his bachelor’s degree in mechanical engineering and his master’s degree in biomedical engineering, both from the University of Twente (The Netherlands). He subsequently earned his PhD at Maastricht University under the supervision of Prof. Dr. Van Blitterswijk and Dr. Rivron, with his thesis entitled Directed assembly and development of engineered tissues using microwell screening platforms.

Prof. Dr. Stefan Giselbrecht
Founder & Scientific Advisor. Dr. Stefan Giselbrecht graduated from the University of Saarbrücken (Germany) in Technical Biology and Bionics/Biology. He received his doctorate in mechanical/micro engineering from Karlsruhe Institute of Technology (KIT, Germany) in 2005.
From 2007 to 2014 he headed the research group 'Biomimetic Microdevices' at the Institute for Biological Interfaces-1 at KIT. Since 2014, he has been working at the MERLN Institute for Technology-Inspired Regenerative Medicine. Currently he is Associate Professor at the Faculty of Health, Medicine and Life Sciences of Maastricht University.

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.

Dr. Ensieh (Ava) Zahmatkesh
Application Specialist. Ensieh (Ava) obtained her Bachelor’s degree in Biology and Master’s degree in histology and embryology. Her Ph.D. project aimed to develop a more reliable, rapid, and cost-effective functional liver organoid derived from human pluripotent stem cells for drug screening and disease modeling applications. To this end, she applied the tissue engineering method and co-culture system along with micropatterning approach. During this project, she tried to recapitulate a natural microenvironment in terms of supportive cells and ECM for further maturation of hepatocyte cells.

Dr. Vinidhra Shankar
Application Specialist. Decoding mammalian embryogenesis using Blastocyst-like structures grown on micro-engineered 3D environment. In September 2019, she started her PhD journey at the MERLN institute in the department of Instructive Biomaterials Engineering (IBE). Her research focusses on using the previously established ‘Blastoid’ (3D blastocyst-like) model system in the lab to extensively study the dynamics of mammalian embryogenesis and decipher some of the missing pieces in the available model systems. She is planning to combine the 3D cell culture systems with innovative bioengineering platforms to recapitulate the in vivo scenario.
