Main Field(s) of Research, Abstract

The laboratory focuses on tissue engineering of bone, pulp and cartilage and is specialized on in situ tissue engineering by using newly developed synthetic andnatural biomimetic materials. In the dental field, beside our pulp regeneration project, we have developed several synthetic and biodegradable guided bone regeneration membranes and have patented the first bioactive degradable guided bone regeneration membrane. Just recently we have unraveled that the bioactivity of these membranes and from the membrane released small chemicals is based on their affinity to bromodomains. Therefore these drugs are epigenetically active. At present wetry to utilize them in clinical applications reaching from bone substitute materials for accelerated bone regeneration to antiresorptive drug for the prevention of osteoporosis.

Main Fields of Research, Keywords

Epigenetics in bone regeneration, osteoconduction, osteoinduction, bone morphogenetic proteins guided bone regeneration, bone regeneration, pulp regeneration, cartilage regeneration , slow release systems for proteins, epigenetically active small chemicals, biomimetic matrices, ECM, tissue engineering, synthetic fibrin, , in vitro bone tissue engineering, surface modification for the attachment of growth factors, anti-resorptive small chemicals, BMP enhancers.

Special Techniques and Equipment

A highly multidisciplinary spectrum of methods is established in the group including 3D-additive manufacturing, molecular biology, animal models, biochemistry, histomorphometry, basic immunological techniques, expression of proteins in E.coli, and the establishment of primary cell cultures including mesenchymal stem cells, periodontal ligament cells, pulp cells, osteoclasts, osteocytes and osteoblasts.

Education and Training

We have training opportunities for PhD students.
