StemBoneReg: Reconstruction of mandibular bone using stem cells and biomedical engineering approaches

Recent project activity
Increased emphasis is being placed on translational research discoveries, which will bring the use of stem cells in laboratory studies into the clinical setting. However, only few early stage clinical studies with a limited number of patients have proven safety of this novel regenerative treatment. According to the clinical database ( and Medline, it appears that our research is at the forefront of regenerative medicine as we have successfully performed an early stage pilot clinical study using stem cell therapy in 11 patients for reconstruction of alveolar bone with excellent results at the 24 month examination. These results pave the way for improved and well-designed phase II clinical trial using stem cell therapy for bone regeneration.
The StemRegBone project consists of a number of sub-projects including therapeutic and safety assessment in clinical trial and optimization of MSC expansion in preclinical studies.
Reconstruction of jaw/alveolar bones using stem cells and biomaterials.
Atrophied bone has a limited spontaneous healing capacity. A clinical trial is designed to demonstrate the safety and efficacy of mesenchymal stem cells (MSC) for making new bone.
Monitoring grafted MSC using a minimally invasive diagnostic concept
The interactions between the transplanted MSCs and host immune cells is under elucidation by liquid biopsy to assess safety and immune efficacy of autologous bone marrow MSC therapy
Optimization and production of clinical grade MSC
For the production of clinical grade, xeno-free culture condition is to be adopted. In this project, the efficacy of using Human Platelet Lysates (HPLs) as an alternative to animal serum (i.e., fatal bovine serum) is tested for MSC expansion for the application of cell transplantation therapy.
Optimization of capacity and cost of ex-vivo expansion using bioreactors to facilitate commercialization of MSC as ATMP
In bone tissue engineering, various bioreactor systems are used to control MSC fate mechanically. In the project, mechanical regulation of MSC dynamics is assessed by applying dynamic culture conditions.
