Regenerative biomechanical cues
Regenerative biomechanical cues are for example the Young’s modulus (e.g. material stiffness) and the patterning of stem cell anchoring points. Oral tissues feature very different properties with elasticities ranging from hard tissue such as bone and teeth to soft tissue such as gum and periodontal ligament. Further, tissue defects and wound dressings exhibit interfaces of different textures that act on stem cells. Those cells sense biomechanical properties by anchoring via integrin-based focal adhesion sites that facilitate actin fiber assembly and reciprocal transformation of biomechanical to biochemical signals. In this context, we focus on how stem cell performance can be directed by such biomechanical cues. This information is important for the development of scaffolds suitable for tissue engineering and for predicting the efficiency of stem cell-based therapies.
