| Outline of Final Research Achievements |
The extracellular matrix (ECM) is dynamically remodeled to regulate stem cell functions during tissue development. Here, we have prepared novel types of matrices that mimic the dynamic variation of ECMs by using simultaneous osteogenesis and adipogenesis of mesenchymal stem cells (MSCs). The matrices had different effects on differentiation of MSCs due to the different compositions depending on the differentiation stage. Late osteogenesis and early adipogenesis (LOEA) and late osteogenesis and late adipogenesis (LOLA) matrices promoted osteogenesis but not adipogenesis. Early osteogenesis and early adipogenesis (EOEA) matrices promoted adipogenesis but not osteogenesis. Early osteogenesis and late adipogenesis (EOLA) did not promote either osteogenic or adipogenesis. The tissue development mimicking matrices can be prepared at large scale and thus should be useful as versatile biomaterials.
