Poly (ε-caprolactone)/layered double hydroxide microspheres-aggregated nanocomposite scaffold for osteogenic differentiation of mesenchymal stem cell

In this study, Three-dimensional porous scaffolds made of Mg/Al-layered double hydroxide (LDH)/polycaprolactone (PCL) nanocomposites with different LDH contents have been prepared for bone tissue engineering applications. The microspheres-aggregated nanocomposite scaffolds were fabricated by freeze-drying and particulate leaching methods. The size of the microspheres ranges from 13 μm to 58 μm, in which the minimum microsphere size was achieved...
