Thin-Layer Hydroxyapatite Deposition on a Nanofiber Surface Stimulates Mesenchymal Stem Cell Proliferation and Their Differentiation into Osteoblasts
Visualization of scaffolds by SEM and confocal microscopy. Prepared scaffolds were visualized using SEM (a, b, c, d). On day 7, MSCs were stained using BCECF-AM and propidium iodide for live/dead staining, and samples were visualized by confocal microscopy (e, f, g, h); PCL/PVA (a, e), PCL/PVA200HA (b, f), PCL/PVA400HA (c, g), and PCL/PVA800HA (d, h).
