A Regulatory Mechanism of a Stepwise Osteogenesis-Mimicking Decellularized Extracellular Matrix on the Osteogenic Differentiation of Bone Marrow-Derived Mesenchymal Stem Cells

Four types of stepwise decellularized ECMs were prepared from bone marrow-derived mesenchymal stem cells undergoing osteogenic differentiation for 0, 7, 14, and 21 days after decellularization.
