Institute for Tendon and Bone Regeneration

Head: Priv.-Doz. Mag. Dr. Andreas Traweger


The Institute for Tendon and Bone Regeneration originates from a research initiative for cell biology and was founded at the end of 2011 by Univ.-Prof. Dr. Herbert Resch, Rector of Paracelsus Medical Private University and Senior Consultant of the University Hospital for Trauma Surgery and Sports Traumatology. This was possible by an endowment by three sponsors – Red Bull GmbH, Rauch GmbH and Rexam PLC, which have financed the institute first for five years. Univ.-Doz. Dr. Hans-Christian Bauer was entrusted as a research professor with the management of the institute for the duration of three years. The work group around Bauer was taken over in the institute and thus the long cooperation between the head of the institute, its employees and the rector was strengthened and expanded.


The name of the new institute reveals its goal: to develop new treatment strategies for defective/damaged tendons and bones, in order to restore their functionality as far as possible. These strategies have to do very often with the potential of the plastic precursor cells which differentiate themselves during the regeneration process in cells with clearly specific functions. In this way, the own healthy cells of the body can be attracted and stimulated. Alternatively, the damaged cells and tissues can be replaced by transplantation. Generally, we follow the "From Bench to Bedside" philosophy and focus primarily on the research of the fundamental mechanisms of the tendons and bone degeneration and their correction. This is done both in vitro and in vivo, in order to be able as a result to develop therapeutic strategies for tissue regeneration.

Research projects and methods


There are already several strategies that are applied in the hospital in order to accelerate the regeneration of the bones, but, as before, new ways were desirable. Certain pathological conditions in the bones can still not be explained and require scientific research. On the other hand, the regeneration of the tendons is still very little understood and in the recent decades it was often neglected. Therefore, the need to research the regeneration capabilities of the tendons is obvious – and, due to the increasing ageing of the population, is becoming even more urgent. One of the possible strategies in both tissues is the use of precursor cells. Therefore, our projects will answer the questions about the nature and the effectiveness of these cells and what significant role they can play in the regeneration. In addition, in the tendon area, the fundamental research of the tendon cells is important and also to what extent their precursor cells play a role in the healthy and the damaged tendons.


Currently running projects:

  • The properties of the perivascular tendon cells in vitro and in vivo
  • The effect of age and gender on the stability of the tendons and the build-up of the tendon and bone structures, in particular of the osteocytes
  • The comparison of the mesenchimales stem cells with tendon precursor cells (TDSCs)
  • Establishing the suitable animal models in order to be able to analyse the regeneration models

Project: Exciting regeneration research – development of a new type of bioreactor for the cultivation of tendons

The injuries and chronic diseases of tendons and ligaments are a big challenge for surgery and there is an urgent need for helpful and quickly effective therapies for the functional tendon regeneration. The tendons are collagen-rich connective bands which are subjected to high mechanical forces, contain relatively small number of cells and because of that they heal very slowly and incompletely. Compared to the tissues with high regenerative potential (e.g. skin or bones), after an injury no functional tissue is formed but in fact cicatrisation occurs. The resulting changes reduce the mechanical properties of the tendons and often it comes to secondary injuries.

In order to be able to develop more effective therapy methods, first the biomechanical and biological processes, which are the cause for the low regeneration capability of the tendons, must be understood. The objective of the project is to build, jointly with the Higher Technical Federal College and Research Institute (HTBLuVA Salzburg; focus of training: biomedicine and healthcare technology) a bioreactor for the organotypical tendon culture which permits continuous measurement of the biomechanical properties of the tendons of rats in vitro. In collaboration with the students of HTBLuVA Salzburg, a bioreactor is going to be built, which permits to cultivate tendon tissue under cyclical or constant tension in vitro and thereby to measure its mechanical changes. The planning and the technical realisation of the bioreactor is done by the students within the framework of their diploma thesis. Thereby there are various "experimental modules" to be realised such as, for example, a mechanical loading and testing module, a module for calibrated tension-based testing as well as the necessary sensors and measurement data logging. In the second phase of the project, the students have an opportunity to operate the bioreactor in the Paracelsus Medical University Salzburg and research various scientific issues. In this way, they have the possibility to learn the real scientific research work in the area of the basic medical research and thus to enter deeper in the use of the bioreactor constructed by them.

The in-vitro culture of tendons in this bioreactor makes possible the research of the cellular, biomechanical and molecular biology changes under various controlled conditions. One test approach must research the effects of the thrombocyte lysate (PRP) on the quality of the tendons, because different tendon diseases are treated often with PRP. However, some advantages of this treatment are still discussed in controversy. The organotypical culture offers the possibility to research the tendons under almost physiological conditions, because only under these conditions the tendon cells embedded in the collagen matrix are screened by a cellular barrier that is similar to the one in vivo.

Project: What tendons want: The influence of the nutrition on the musculoskeletal system

The tendons are important component part of the musculoskeletal system and serve as connection and force transmitters between the muscles and the bones. They are very elastic and at the same time have high tensile strength. Histologically, the tendon tissue is considered as tight connecting tissue with parallel fibres, which is distinguished by its high collagen content and low cell density. In addition, the tendons have a very small regeneration/healing potential.

Sports accidents, but also household or workplace accidents are the cause of injuries of the support and musculoskeletal system. Along with this, injuries of the tendons and bands often occur, such as, for example, Achilles tendon ruptures in soccer players, cruciate ligament ruptures in skiers or injuries of the rotator cuff of the shoulders after physical overloads or falls.

Usually with the old age the quality of the tendons decrease. In addition, intrinsic factors also play a role (e.g. gender, weight, chronic diseases and their medication of) as well as extrinsic factors (e.g. loading and overloading through physical activities and way of life) play a role in the degeneration of the tendons. The current works contain also indications that the blood sugar level also has an effect on the tendon properties. Our work group at Paracelsus Medical University was able to show that the tendon cells produce insulin and react with this release to the increase in the glucose level in the environment.

In this project,the effect of factors such as nutrition – in particular of glucose-rich food – both on the quality of the extracellular matrix and the microstructure and function of the tendons is going to be researched. Thereby molecular biology, histological and biomechanical methods of analysis are used to this purpose. Many of these analyses will be made jointly with the students of the Europe and Federal Grammar School Salzburg-Nonntal (Karlheinz-Böhm Grammar School) and the Bundesgymnasium & Bundesrealgymnasium Hallein. Within the framework of the biology elective subject, the students receive an overview of the structure and functioning of the musculoskeletal system, which otherwise is at a higher level than the level taught in the regular school education. In addition, they receive an overview of the work in a laboratory for molecular biology, cell biology and histology and also access to a scientific research workplace outside of the school. They partially plan experiments individually as well as perform and evaluate experiments under the supervision of a scientist.

The objective of the project is to study the effect of the nutrition-based sugar intake on the molecular and cellular properties of the tendon cells and tendon tissue and possibly to create the scientific groundwork for a form of conservative therapy (such as, for example, a special diet) which can influence favourably the functional regeneration of the tendons after an injury.
