Fig. 2. Scanning electron microscopy images of the explanted unsintered-hydroxyapatite/poly-L lactic acid (u-HA/PLLA) nanocomposite at increasing magnifications 20 months after surgical implantation. At lower magnification (A-C), the surface of the device appears roughened with pores. At higher magnification, cells and exosomes are observed attached to the surface (D), and fibrous fibers have formed bundles and adhered to the surface of the u-HA/PLLA nanocomposite (E, F).
