Exosomes Derived from Nerve Stem Cells Loaded with FTY720 Promote the Recovery after Spinal Cord Injury in Rats by PTEN/AKT Signal Pathway

<div>FTY720-NSC-Exos restored histological abnormalities and alleviated damages in spinal cord. (a) Representative microphotographs of HE (original magnification 20x, 100x) and TUNEL staining in each group (original magnification 200x, 400x). (b) Semiquantitative estimate of the histological lesions. (c) Quantitative analysis of the neuronal apoptosis in the lesions site of the spinal cord (<span class="nowrap"><svg height="14.4349pt" id="M27" style="vertical-align:-3.638201pt" version="1.1"
