OxTalks is Changing
OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Fibroblast functions in tissue repair and fibrosis
In person
Tissues lose integrity upon injury. To rapidly restore mechanical stability, a variety of different cell types are activated to become myofibroblasts. Hallmarks of the myofibroblast are secretion of extracellular matrix, development of adhesion structures with the extracellular matrix, and formation of contractile stress fiber bundles. Rapid repair comes at the cost of tissue contracture due to the inability of the myofibroblast to regenerate tissue. When contracture and extracellular matrix remodeling become progressive and manifest as organ fibrosis, stiff scar tissue obstructs and ultimately destroys organ function. Pivotal for the formation and persistence of myofibroblasts are mechanical stimuli arising during tissue repair and chronic presence of inflammatory cells. I will provide an overview on our current projects aiming at investigating of how mechanical factors orchestrate the activation of myofibroblasts. I will focus on myofibroblast interactions with macrophages and extracellular matrix in persisting wound environments, using lung injury and implant fibrosis as paradigms. By understanding and manipulating myofibroblast mechanoperception and intercellular communication, we will be able to devise better therapies to reduce scarring and support normal wound healing in organ and implant fibrosis.
