Exosomes from antler stem cells alleviates MSC senescence and osteoarthritis

Project description:The therapeutic functions of stem cells were mainly depending on paracrine effects rather than their own proliferation and differentiation on site. In advantage of easy to collected from conditioned medium, have contents of cytokines, growth factors, signaling lipids, mRNAs, and regulatory miRNAs, exosomes from stem cells were considered to be a promising material for stem cell-based cell-free therapies. In traditional Chinese medicine, antler extracts have been used to alleviates aging and aging related diseases. We have demonstrated that exosomes from antler stem cells (ASCs), the source of the annual full regeneration of deer antler, could alleviate cellular senescence and aging related diseases. With exosomes treatment, the senescent phenotype of primary MSCs and hMSCs at late passage were significantly mitigated. When injected into articular cavity, exosomes from ASCs markedly promote joint function recovery and bone and cartilage regeneration. By LC-MS/MS assay, we found that exosomes from ASCs contain various proteins which in the regulation of biological processes including cell proliferation and migration, immunoregulation, wound healing and angiogenesis. With the advantages of abundant sources, low risk of tumorigenicity and immunogenicity, exosomes from ASCs may consider as a promising bio-material for cell-free therapies in the future.

Exosomes from MSC facilitate diabetic wound healing by promoting angiogenesis

Project description:Mesenchymal stem cell (MSC)-derived exosomes had been reported to be a prospective candidate in accelerating diabetic wound healing. Hence, this study intended to explore whether exosomes originating from the human umbilical cord MSC (hucMSC) could display a superior proangiogenic effect on diabetic wound repair and its underlying molecular mechanism.

Exosomal lncRNA sequencing in Atorvastatin treated and non-treated MSC-derived exosomes

Project description:In order to investigate the molecular mechanisms underlying the further enhancement of Atorvastatin pretreated MSC-derived exosomes (MSCATV-Exo) in cardiac protection, we performed lncRNA sequencing on exosomes secreted from ATV pretreated MSCs and non treated MSCs to identify differentially expressed lncRNA. We found that 450 lncRNAs were identified to be upregulated and 1332 lncRNAs downregulated (over 1.5 fold change) in MSCATV-Exo compared to MSC-Exo.

Exosomal microRNA sequencing in Tongxinluo pretreated and non-treated MSC-derived exosomes

Project description:In order to investigate the specific mechanisms underlying the cardioprotective effects of Tongxinluo pretreated MSC-derived exosomes (MSCTXL-Exo) in cardiac repair, we performed microRNA sequencing on exosomes secreted from Tongxinluo pretreated MSCs and non-treated MSCs to identify differentially expressed miRNA. We found that 18 miRNAs were identified to be upregulated and 25 miRNAs downregulated (over 2-fold change) in MSCTXL-Exo compared to MSC-Exo.

miRNA expression profile of cells and exosomes

Project description:We hypothesized that miRNAs in the bone maroow mesenchymal stem cells (BM-MSC)-derived exosomes contributed to the phenotype change of breast cancer cells through exosome transfer. We analyzed the miRNA expression signature in BM-MSC-derived exosomes. We compared the miRNA expression levels in exosomes between BM-MSCs and adult fibroblasts (as a control). In this study, miRNA expression including in bone-marrow mesenchymal cell (BM-MSC)-derived exosomes was examined, and compared with that of exosomes derived from adult fibroblast cells or the BM-MSC cells. In addition, miRNA expression of BM-MSC exosomes was also compared with that of breast cancer cells with or without cancer stem cell marker.
