Microenvironments for New Therapies

The vision of our group is to render bioengineered microenvironments powerful tools for the treatment and diagnosis of disease. The activity of the group is strongly translation-oriented, based on well-established collaborations with medical professionals, namely neurosurgeons and orthopaedic surgeons. Osteoarticular diseases, namely those associated with ageing (e.g. spine degeneration and osteoarthritis), are major areas of application. Pivotal in our strategy is the modulation of the inflammatory response, namely through immunomodulatory biomaterials, which are strongly influenced by our “learn with nature” approach. The extracellular matrix (ECM) is a permanent source of inspiration for the bioengineered microenvironments developed by us. We bioengineer matrix-inspired biomaterials that modulate the inflammatory response, including hierarchically designed matrices and nanocomplexes for tissue regeneration.

Morphology of macrophages differentiated on surfaces can be observed by staining for F-actin filaments (red) and nuclei (green).
