Prof. Dr. Tim Welting / Maastricht University / The Netherlands

Tim Welting is professor at the department of orthopedic surgery of MUMC+ and an expert in molecular cartilage biology. He is head of the Laboratory for Experimental Orthopedics and is principal investigator and group leader of the Molecular Cartilage Biology research group. He recieved his PhD in biochemistry from the Radboud University Nijmegen in 2007.

The clinic of the Department of Orthopaedic Surgery is a Top Referral clinic for amongst others OA and cartilage repair surgery, and for many decades it has been our mission to provide innovation in orthopaedic health care through translating basic science towards meaningful clinical applications. We are leading the Dutch joint preservation clinics network. We approach our clinical orthopaedic challenges through basic molecular and preclinical research in our Laboratory for Experimental Orthopaedics, a ReumaNL Research Centre of Excellence. We are working on focal cartilage defects and attenuation of the progression of OA with a research team of more than 20 skilled experts bridging and connecting basic chondrocyte molecular biology with orthopaedic medical engineering. We have committed our research activities towards the development of autologous biological and artificial chondro-compatible implants for focal cartilage defects and towards the identification of osteoarthritis disease-modifying drugs (peptides in particular). Pre-clinical animal models for cartilage defects and OA are fully operational and lined-up with advanced high-resolution MR imaging for follow-up of treatment efficacy. Together with our growing (OA) joint tissue biobank, in-house orthopaedic clinical trial bureau to initiate and coordinate (first-in-man) clinical trials, and a campus that actively supports and propels valorisation activities, we are in a unique environment to enable the translation of science products towards meaningful clinical applications. In OSTASKILLS, UM offers specific training in (OA) chondrocyte and cartilage molecular biology; the design of drug screening approaches for OA; a variety of preclinical animal models for OA, cartilage defects, cartilage regeneration, and high resolution MR imaging, functional, biomolecular and histological follow-up; and clinical study design/first-in-man clinical studies for joint preservative new treatments in GCP-trained experienced orthopaedic clinical trial centre. UM has a solid track record of European training programmes: PersonalizeAF (MSCA-ITN-2019), MARCIUS, SINERGIA (MSCA-ITN-2019), THERADNET (MSCA-ITN-2019) and INSPIRE.

Prof. Dr. Andrea Barbero /University Hospital Basel / Switzerland

The common denominator of the research projects performed in the Cartilage Engineering Group (Prof. Dr. Andrea Barbero) is related to the establishment of three-dimensional culture systems, combining interdisciplinary efforts in cell biology, engineered technologies and materials science. These systems are used as model to investigate fundamental aspects of tissue (mainly cartilage) development, and as grafts to induce tissue regeneration.
Prof. Barbero`s group demonstrated that adult human nasal chondrocytes (NCs) display a large degree of plasticity and unique regenerative properties. Two phase I clinical trials at the University Hospital Basel demonstrating that engineered grafts based of nasal chondrocytes can be safely used for the treatment of nasal and articular cartilage. A phase II clinical study is now ongoing to assess the efficacy of such experimental procedure.
Currently, the potential of NCs for intervertebral disc (IVD) repair is being explored.

The multidisciplinary group of the Laboratory of Tissue Engineering includes biologists, engineers and clinical staff, has a wide network of cooperation with international biotech industries and academic institutes, and is funded through public, private or foundation grants, acquired on a competitive basis. The core competence of the group lies in development of 3D cell culture models as well as in the engineering of cellular grafts to repair cartilage and bone tissues. As part of UNIBAS close interactions between the lab and the clinic allow for obtaining biopsies of human tissues, after patient informed consent as well as the conduction of clinical trials. The group established a streamlined automated manufacturing of these implants in perfusion-based bioreactor systems. After establishing a GMP-compliant quality management system, several clinical phase I and II trials have been conducted, translating the findings of the lab from bench to bedside. An international multicentre phase II study within the BIO-CHIP project (H2020 681103), is currently ongoing with 108 patients in 5 clinical centres treated with tissue engineered cartilage grafts for repair of focal cartilage lesions (about 2/3 of the patients enrolled). The Clinical Trial Unit (CTU) of the University Hospital Basel offers support for clinical trials.

The OSTASKILLS training plan foresees access to 1) hands-on training experience, 2) clinical data and theoretical training on biological systems provided by clinical-oriented partners (collaborators). The PhD candidate will validate the performance of own development complying with regulatory requirements of DDP. UNIBAS provides strong research supervision and intensive training in material sciences, biomaterial/biological integrated research design, medical device manufacturing. UNIBAS is a world leader in surgical training, where the doctoral candidate will collect experience, and deepen knowledge in the application of 3D-printed materials and their translation into the clinic. The candidates will be trained on in vitro and ex vivo studies, using chondrocytes and mesenchymal stem cells for example, and the use of specifically design bioreactors allowing control over the tissue environment.

UNIBAS comprises state-of-the-art facilities for the cell culture, cytofluorimetric activities (FACS cell sorting instrument), biochemistry, histology, animal facilities (mice, rats and rabbits). Furthermore, also in EU context there a vast experience in trainings of ESR’s, for example with MSCA-ITN-2019: “Advanced technologies for drug discovery and precision medicine: in vitro modelling human physiology and disease” and EU-Horizon 2020: “From Epigenetics of Cranial Neural Crest Plasticity to Intervertebral Disc Regeneration”.

Ass. Prof. Dr. Paul Bourgine / Lund University / Sweden

Paul currently holds an assistant professor position at the University of Lund (Sweden), where he leads the Cell, Tissue & Organ engineering laboratory ( His research aims at studying Bone as an organ system, understanding from a fundamental perspective how its constitutive tissues (bone, cartilage, marrow) form, interact and regenerate. By exploiting innovative in vitro/in vivo models of bone formation, he ambitions to compile human specific knowledge helping the design of regenerative therapies. One of the group favorite approaches consists in using death-inducible human cell lines as factory units to produce molecularly customized biological tissues, subsequently decellularized for skeletal repair. From bone, Paul´s interest extended to the hematopoietic system where the lab intends to understand the function of human mesenchymal cells in supporting blood stem cell renewal and differentiation.

Paul studied Biotechnology at the Ecole Superieure de Biotechnologie de Strasbourg, a European school joint venture of the universities of Freiburg, Strasbourg, Basel and Karlsruhe. He obtained his engineering diploma in 2010 after a stay at the Ragon Institute of Harvard, MIT and MGH (Boston, USA). Paul subsequently moved to Switzerland and received his Ph.D in Cell Biology from the University of Basel in 2013. After a three years post-doc at the Biosystem department of the ETH-Zürich, he opened his lab in 2018 at the faculty of medicine in Lund, embedded within the Stem Cell Centre and the Wallenberg Centre of Molecular medicine framework.

In the past 3 years, Paul has secured over 5M euros in funding as principal investigator, through prestigious national (e.g. Swedish Research foundation starting grant) and international calls (e.g. ERC Starting grant). Paul´s group has published in highly ranked journals including Advanced Materials, PNAS, Cell Stem Cell, Advanced Functional Materials, Trends in Biotechnology, Blood and his strongly connected to the TERMIS, ISSCR and ISEH societies. His research is at the crossroad between tissue/organ engineering and stem cell technologies, exploiting state-of-the-art technologies such as personalized engineering of human bone organs in mice, 3D quantitative microscopy, single cell transcriptomics, and 3D-printing of custom bioreactor system.  

Lund University is one of the biggest campuses worldwide, hosting over 44´000 students.
