C02 - Electrical and mechanical stimulation of hyaline cartilage: Characterisation of biological response and stimulation parameters
Summary of the work programme
Within this project, the influence of electrical and mechanical stimulation on chondrogenic differentiation of human cartilage cells and mesenchymal stem cells will be analysed in vitro. For this purpose, we will use a specific stimulation chamber for experimental analyses of single and combined stimulation. Further, we will establish a multiphysics simulation model which should comprise the stimulation parameters and their influence on cells resulting in an enhanced understanding of the stimulation process. In the first funding period, the main goal of C02 is to establish and achieve optimised 3D cultivation of human chondrocytes and mesenchymal stem cells on novel collagen- and hydrogel-based biomaterials (scaffolds) by means of combined electrical and mechanical stimulation to derive effective therapeutic approaches.
