Scientific Focus
Current Research Interests
Stem Cell Imaging: The ultimate goal of my research is to develop clinically applicable, non-invasive and repeatable imaging tools, which can be used for long-term tracking of transplanted stem cells in bone defects and osteochondral defects. I evaluate novel contrast agents for non-invasive in vivo detection of stem cells with MR imaging in mouse models of bone and cartilage repair, I test smart, activatable MR contrast agents, which can provide non-invasive information about the viability and in vivo differentiation of transplanted stem cells, and I evaluate specific nanoparticle-based labels for immune cells, which allow monitoring host responses to stem cell transplants. The new imaging tools are used to improve bone and cartilage regeneration outcomes of mesenchymal stem cells, adipose derived stem cells and induced pluripotent stem cells.
