Focus Area
Tissue Engineering

Since the late 1800s, many methods for reconstructing non-ossifying adult calvarial defects have been developed. Yet, the search for the source of donor materials continues. Recent findings have suggested that adipose tissue, capable of in vitro adipogenic, osteogenic, chondrogenic, and neurogenic differentiation, could contain multi potent stromal progenitor cells. These findings opened new possibilities for reconstruction of calvarial defects using tissue engineering and cell-based therapies. While much interest has been generated over the multilineage potential of these adipose-derived mesenchymal stromal cells (ADMSCs), very little is known about the effect of tissue donor age on the biology or function of ADMSCs. We hypothesize that juvenile and adult ADMSCs have different biologic profiles and thus different abilities to re-ossify calvarial defects. In the first Specific Aim, we will determine the differences in the molecular biology of juvenile and adult ADMSCs undergoing osteogenesis differentiation. Alterations in osteogenic gene expression will be assessed using micro array technology and quantitative, real-time RT-PCR. In the Second Specific Aim, we will utilize an established mouse critical size calvarial defect model to determine the ability of juvenile and adult ADMSCs to re-ossify critical size calvarial defects. The research proposed in this application will help to direct future strategies in cell-based therapies for calvarial healing. This will facilitate the development of novel, clinically applicable techniques with which to reconstruct non-healing calvarial defects.
