Abstract
Background Bone-tendon injury is characterized by poor self-healing. It is established that exosomes are favorable for tissue repair and regeneration. However, their effect on bone-tendon healing has not yet been determined. Purpose To compare the effectiveness of exosomes derived from adipose-derived mesenchymal stromal cells (ADSC-Exos) and bone marrow-derived mesenchymal stromal cells (BMSC-Exos) on bone-tendon interface healing in murine rotator cuff injury model and explore the underlying mechanisms thereof. Study Design Controlled laboratory study. Methods A total of 63 male C57BL6 mice with rotator cuff injuries underwent surgery and were randomly assigned to a control group treated without exosomes (n = 21), an ADSC-Exos group (n = 21), or a BMSC-Exos group (n = 21). The mice were sacrificed 4 or 8 weeks after surgery, and tissues were collected for histologic examination and radiographic and biomechanical testing. For exosome tracing in vivo, mice were sacrificed 7 days after surgery. A series of functional assays (radiographic evaluation, proliferation assay, Alizarin Red staining, alkaline phosphatase staining and activity, Alcian blue staining, quantitative polymerase chain reaction analyses, and glycosaminoglycans quantification) were conducted to evaluate the effect of exosomes on the cellular behaviors of the BMSCs in vitro. A statistical analysis of multiple-group comparisons was performed by 1-way analysis of variance, followed by the Bonferroni post hoc test to assess the differences between the 2 groups. Results The ADSCs and BMSCs were positive for surface markers CD29 and CD90 and negative for surface markers CD34 and CD45 and could differentiate into osteoblasts, chondrocytes, and adipocytes. Exosomes showed a cup- or sphere-shaped morphology and were positive for CD63 and TGS101. Local injection of ADSC-Exos and BMSC-Exos could recruit BMSCs and promote osteogenesis, chondrogenesis, and bone-tendon healing. In vitro, ADSC-Exos and BMSC-Exos could significantly promote the proliferation, migration, osteogenic differentiation, and chondrogenic differentiation ability of BMSCs. In vivo, ADSC-Exos and BMSC-Exos significantly accelerated bone-tendon injury healing, with no significant statistical difference between them. Conclusion ADSC-Exos and BMSC-Exos exhibited similar therapeutic effects on bone-tendon healing in our murine animal model. Clinical Relevance ADSC-Exos and BMSC-Exos may be used to develop a new cell-free therapy method for promoting rotator cuff injury repair.

Abstract
Bone metastasis is a frequent and incurable consequence of advanced prostate cancer (PC). An interplay between disseminated tumor cells and heterogeneous bone resident cells in the metastatic niche initiates this process. Melanoma differentiation associated gene-9 (mda-9/Syntenin/syndecan binding protein) is a prometastatic gene expressed in multiple organs, including bone marrow-derived mesenchymal stromal cells (BM-MSCs), under both physiological and pathological conditions. We demonstrate that PDGF-AA secreted by tumor cells induces CXCL5 expression in BM-MSCs by suppressing MDA-9-dependent YAP/MST signaling. CXCL5-derived tumor cell proliferation and immune suppression are consequences of the MDA-9/CXCL5 signaling axis, promoting PC disease progression. mda-9 knockout tumor cells express less PDGF-AA and do not develop bone metastases. Our data document a previously undefined role of MDA-9/Syntenin in the tumor and microenvironment in regulating PC bone metastasis. This study provides a framework for translational strategies to ameliorate health complications and morbidity associated with advanced PC.

Abstract
BACKGROUND AIMS Bone marrow-derived mesenchymal stromal cells (BMSCs) are being extensively investigated as cellular therapeutics for many diseases, including cardiovascular diseases. Although preclinical studies indicated that BMSC transplantation into infarcted hearts improved heart function, there are problems to be resolved, such as the low survival rate of BMSCs during the transplantation process and in the ischemic region with extreme oxidative stress. Autophagy plays pivotal roles in maintaining cellular homeostasis and defending against environmental stresses. However, the precise roles of autophagy in BMSCs under oxidative stress remain largely uncharacterized. METHODS BMSCs were treated with H2O2, and autophagic flux was examined by means of microtubule-associated protein 1A/1B-light chain 3 II/I ratio (LC3 II/I), autophagosome formation and p62 expression. Cytotoxicity and cell death assays were performed after co-treatment of BMSCs by autophagy inhibitor (3-methyladenine) or autophagy activator (rapamycin) together with H2O2. RESULTS We show that short exposure (1 h) of BMSCs to H2O2 dramatically elevates autophagic flux (2- to 4-fold), whereas 6-h prolonged oxidative treatment reduces autophagy but enhances caspase-3 and caspase-6-associated apoptosis. Furthermore, we show that pre- and co-treatment with rapamycin ameliorates H2O2-induced caspase-3 and caspase-6 activation and cell toxicity but that 3-methyladenine exacerbates H2O2-induced cell apoptotic cell death. CONCLUSIONS Our results demonstrate that autophagy is critical for the survival of BMSCs under oxidative conditions. Importantly, we also suggest that the early induction of autophagic flux is possibly a self-defensive mechanism common in oxidant-tolerant cells.
