Synthetic extracellular matrix analogs guiding the repair and regeneration of musculoskeletal tissues

With a growing and aging population, the demand for synthetic grafts assisting the repair and reconstruction of musculoskeletal tissue defects induced by trauma, aging, cancer and metabolic diseases is quickly rising. Our lab is interested in designing synthetic extracellular matrix (ECM) analogs capable of promoting the repair or guiding the regeneration of musculoskeletal tissues. These synthetic constructs are also programmed with unique physical properties to facilitate surgical handling (e.g. deployable, elastic, injectable) and proper in vivo degradation. Specific research directions include:

• Development of chondrogenic / osteogenic tissue grafts for the repair and reconstruction of musculoskeletal defects via minimally invasive surgical procedures;
• Development of organic/inorganic composite bone grafts with tailored mechanical properties and controlled structural integration of the organic and inorganic components for weight-bearing applications;
• Development of new methods for spatially controlled presentation and temporally controlled release of growth factors and cytokines on and from 3-dimentional synthetic tissue grafts.

  

  We are also interested in nanostructured biomaterials for therapeutic and biomedical imaging applications.
