Abstract
Various approaches have been evaluated for developing three-dimensional (3D) scaffolds for modeling or engineering of the bone tissue. However, most of such attempts have come up short in mimicking the natural bone tissue extracellular matrix (ECM) microenvironment, especially its natural bioactive content. Here we describe the methodology for the preparation of a natural ECM-based multichannel construct as a biomimetic 3D bone tissue model. We elucidate the construction of the composite scaffold incorporating decellularized small intestinal submucosa ECM, synthetic hydroxyapatite and poly(ε-caprolactone), and the mechanical stimulation of the cell-seeded construct under bioreactor culture.
