Exosomes Secreted from Hypoxia-Preconditioned Mesenchymal Stem Cells Prevent Steroid-Induced Osteonecrosis of the Femoral Head by Promoting Angiogenesis in Rats

<div>Characterization of Exos<sup>N</sup> and Exos<sup>H</sup>. (a) Typical cup-shaped morphology assessed by TEM. (b) Western blot analysis of CD9, TSG101, and Calnexin expression in Exos<sup>N</sup> and Exos<sup>H</sup>. (c) The size distribution of Exos<sup>N</sup> and Exos<sup>H</sup> assessed by nanoparticle tracking analysis. (d) The concentration analysis of Exos<sup>N</sup> and Exos<sup>H</sup> assessed by nanoparticle tracking analysis. The results are from three independent experiments.
