The work of our group aims at understanding how biomechanical cues of the extracellular environment, e.g. micropatterning of cell adhesion points and substrate/matrix stiffness/elasticity govern cell behaviour, in order to maintain or modulate cell and tissue homeostasis.
To this end, identification and characterization of mechano-sensitive molecules is indispensible. In this context, molecules of particular importance address cell functions including (i) mechanopercetion, (ii) signal-/mechanotransduction, and (iii) execution of mechano-response. To realize this aim, we employ simple monolayer cultures and/or interactive co-cultures of tissue-relevant cells, considering physiological, i.e. soluble growth factor-orchestrated in vivo-relevant cell-to-cell-interactions. Tissues addressed include epithelia in conjunction with connective tissue counterparts of oral cavity and skin, the periodontal ligament as well as the alveolar bone, but also cornea. As a prospective goal, we focus on translation of the experimental progressive elucidation of biomechanics in mechano-signalling terms into material science, i.e. the creation of new tissue-supporting biomaterials.
