In Vivo Study of Ligament-Bone Healing after Anterior Cruciate Ligament Reconstruction Using Autologous Tendons with Mesenchymal Stem Cells Affinity Peptide Conjugated Electrospun Nanofibrous Scaffold
Schematic illustration of electrospinning devices and scanning electron microscope observation of nanofibers characteristics in lattice-like electrospun scaffolds. (a) Schematic diagram of electrospun scaffold device showed lattice-like fibers collecting by copper wire grid. (b) Picture of scaffold showed general view of lattice-like PLLA meshes. ((c), (e), and (f)) Micrographs showed nanofibers distribution in different regions of lattice-like PLLA meshes. Detailed view showed local enlarged fibers on ridge (e) and nonwoven region (f) of each lattice. (d) Histogram showed distribution of nanofibers’ diameter in scaffolds.
