Research Areas
The Regenerative Medicine Program focuses on the development and in vitro generation of novel, cell based therapies. The group’s research expertise lies in the fields of tissue engineering, cell based therapies and disease modelling.
- Tissue engineering : These include tissue engineered blood vessels, heart valves as well as microscale strategies for myocardial regeneration. Presently utilized heart valve and blood vessel prostheses carry disadvantages for the patients mainly because non-living, artificial devices are inserted into the human organism. Tissue engineering enables the in vitro production of autologous, living and functional replacements with the capacity of growth for congenital application as an alternative to state of the art artificial replacements.
- Cell Transplantation : An additional focus is the development of cell based implants based on the design of in vitro generated microtissues to improve myocardial functionality of the diseased heart.
- Disease Modelling : Furthermore, we accomplish disease modelling studying e.g. inflammatory processes that occur in the early development of arteriosclerosis.
Selected research projects:
- LifeValve:
LifeValve is a collaborative project funded by the European Commission under the Seventh European Framework Programme and brings together a unique consortium of academic and industrial partners from Switzerland (Leading House), Germany, The Netherlands, Austria and Hungary. The principal objective of the LifeValve project is to develop a new therapeutic strategy to treat heart valve disease patients more efficiently.
- Advanced Cell Therapies for Cardiac Repair:
Advanced Cell Therapies for Cardiac Repair is a collaborative project funded by the Special Program University Medicine (SPUM) launched by Swiss National Science Foundation. The project aims to develop an advanced cell therapy concept for the injured heart. Leaded by Zurich group, the consortium comprises the partner groups from Lausanne and Geneva. The expertise of the consortium ranges from human embryonic (hESC) and induced pluripotent stem cells (iPSC) to resident cardiac (CSC) and adult mesenchymal stem cells (MSC). The main objective of the project is to compare in a systematic manner the cell types at hands, and to evaluate whether it is possible to overcome cell-specific limitations. The best cell type, delivery format and delivery time will be evaluated in a defined timeline from in vitro to in vivo tests with regard to a realistic clinical implementation. Next to the development of novel cell therapy concept, the consortium provides the thoughtful training program for the clinical candidates. Their career development plans will enable them to qualify among the first generation of scientifically trained clinical specialists for the routine use of cell-based therapies for the treatment of cardiac diseases.
