The Tissue Engineering group, founded in 2006, is one of four research groups at the Department of Clinical Dentistry. The group, led by Prof. Kamal Mustafa, aims to address the shortage of tissues available for repair & regeneration. It includes a multidisciplinary team of scientists, clinicians & bioengineers working in close collaboration with national & international partners. Currently, we are developing functional engineered bone-tissue constructs, with combinations of cells, growth factors & the appropriate biomaterial scaffolds. The scope of our work includes all aspects of pre-clinical & clinical biomedical research.  Read more

The group has consistently received funding from national and international (including EU) agencies to partner and coordinate large research projects. Currently, four major projects are ongoing:

- Trond Mohn Foundation (StemBoneReg)              

- Research Council of Norway (NFR BEHANDLING)

- EU MAXIBONE                                                       

- Commercialising R&D results (NFR FORNY2020)

We also provide a Micro-CT Core Facility for both internal (UiB) and external users. Read more
