Abstract
Investigating the role of cranial bone marrow mesenchymal stem cells (cBMMSC) based on nanosilver hydrogel nerve conduits in the repair of spinal cord injury. Thirty adult Wistar rats, male and female, with body mass of 210-240 g, were selected as experimental animals and divided into control group and experimental group, 15 rats each, by random number table method. The experimental group was treated with spinal cord injury and localized transplantation of cBMMSC-containing nanosilver hydrogel nerve conduits, while the control group was treated with spinal cord injury and localized transplantation of cBMMSC-free nanosilver hydrogel nerve conduits. Four weeks after transplantation, the expression of neuron-specific enolase (NSE) in rat anti-human nuclear monoclonal antibody (MAB1281)-positive cells was detected by immunostaining in spinal cord tissue sections of the two groups to assess the differentiation of cBMMSC to neuron-like cells in the nerve conduits after transplantation; the number of BrdU-positive cells was detected to assess the neuronal regeneration of the localized spinal cord injury of the two groups; and the length of axons was observed with laser Confocal photography was used to observe the length of axons; HE staining was used to observe the scarring and cavities in the spinal cord sections of the two groups; immunofluorescence was used to detect neuron-like markers (Nestin, NSE, NF200, GFAP) in the two groups, and the OD values were determined by the Image Processing and Analysis System (IPAAS); and Western blot was used to detect the neurotransmitters of motor fibres, acetylcholinesterase (ChAT), sensory fibres, and sensory fibres, as well as the neurotransmission of motor fibres, acetylcholine production-limiting enzyme (ChAT) and sensory fibre neurotransmitter glutamate synthase (GOGAT); motor function was assessed by BBB score; somatosensory evoked potentials (SEPs) and motor evoked potentials (MEPs) were detected by body surface electrode assay in the two groups, and the neurophysiological recovery effect was evaluated. Four weeks after transplantation, the NSE content of MAB1281-positive cells in the experimental group was significantly higher than that of the control group; the number of BrdU-positive cells and axon length were significantly greater than that of the control group (p < 0.05); the scarring and cavitation of spinal cord slices were significantly lighter than that of the control group; the expression levels of Nestin, NSE, NF200, GFAP, ChAT, GOGAT, and BBB scores were significantly higher than that of the control group (p < 0.05); SEP and MEP latency time were significantly shorter than that of the control group (p < 0.05), and wave amplitude was significantly greater than that of the control group (p < 0.05). The cBMMSC transplantation based on nanosilver hydrogel nerve conduit was effective in repairing spinal cord injury, promoting neuronal and axonal regeneration, and restoring neuromotor and electrophysiological functions.

Overexpression of Wnt5a promoted the protective effect of mesenchymal stem cells on Lipopolysaccharide-induced endothelial cell injury via activating PI3K/AKT signaling pathway. BMC Infect Dis 2024; 24:335. [PMID: 38509522 PMCID: PMC10953236 DOI: 10.1186/s12879-024-09204-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Accepted: 03/07/2024] [Indexed: 03/22/2024] Open
Abstract
BACKGROUND Lung endothelial barrier injury plays an important role in the pathophysiology of acute lung injury/acute respiratory distress syndrome (ALI/ARDS). Mesenchymal stem cells (MSCs) therapy has shown promise in ARDS treatment and restoration of the impaired barrier function. It has been reported that Wnt5a shows protective effects on endothelial cells. Therefore, the study aimed to investigate whether overexpression of Wnt5a could promote the protective effects of MSCs on Lipopolysaccharide (LPS)-induced endothelial cell injury. METHODS To evaluate the protective effects of MSCs overexpressing Wnt5a, we assessed the migration, proliferation, apoptosis, and angiogenic ability of endothelial cells. We assessed the transcription of protective cellular factors using qPCR and determined the molecular mechanism using Western blot analysis. RESULTS Overexpression of Wnt5a upregulated the transcription of protective cellular factors in MSCs. Co-culture of MSCWnt5a promoted endothelial migration, proliferation and angiogenesis, and inhibited endothelial cell apoptosis through the PI3K/AKT pathway. CONCLUSIONS Overexpression of Wnt5a promoted the therapeutic effect of MSCs on endothelial cell injury through the PI3K/AKT signaling. Our study provides a novel approach for utilizing genetically modified MSCs in the transplantation therapy for ARDS.

Abstract
Articular cartilage injury is a prevalent clinical condition resulting from trauma, tumors, infection, osteoarthritis, and other factors. The intrinsic lack of blood vessels, nerves, and lymphatic vessels within cartilage tissue severely limits its self-regenerative capacity after injury. Current treatment options, such as conservative drug therapy and joint replacement, have inherent limitations. Achieving perfect regeneration and repair of articular cartilage remains an ongoing challenge in the field of regenerative medicine. Tissue engineering has emerged as a key focus in articular cartilage injury research, aiming to utilize cultured and expanded tissue cells combined with suitable scaffold materials to create viable, functional tissues. This review article encompasses the latest advancements in seed cells, scaffolds, and cytokines. Additionally, the role of stimulatory factors including cytokines and growth factors, genetic engineering techniques, biophysical stimulation, and bioreactor systems, as well as the role of scaffolding materials including natural scaffolds, synthetic scaffolds, and nanostructured scaffolds in the regeneration of cartilage tissues are discussed. Finally, we also outline the signaling pathways involved in cartilage regeneration. Our review provides valuable insights for scholars to address the complex problem of cartilage regeneration and repair.

Umbilical Cord Mesenchymal-Stem-Cell-Derived Exosomes Exhibit Anti-Oxidant and Antiviral Effects as Cell-Free Therapies. Viruses 2023; 15:2094. [PMID: 37896871 PMCID: PMC10612094 DOI: 10.3390/v15102094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 10/09/2023] [Accepted: 10/13/2023] [Indexed: 10/29/2023] Open
Abstract
The oxidative stress induced by the accumulation of reactive oxygen species (ROS) can lead to cell aging and death. Equally, the skeletal muscle usually hosts enteroviral persistent infection in inflammatory muscle diseases. As excellent bioactive products, the exosomes derived from umbilical cord mesenchymal stem cells (ucMSCs) have been proven to be safe and have low immunogenicity with a potential cell-free therapeutic function. Here, exosomes derived from ucMSCs (ucMSC-EXO) were extracted and characterized. In a model of oxidative damage to skin fibroblasts (HSFs) under exposure to H2O2, ucMSC-EXO had an observable repairing effect for the HSFs suffering from oxidative damage. Furthermore, ucMSC-EXO inhibited mitogen-activated protein kinases (MAPK), c-Jun N-terminal kinase (JNK), and nuclear factor kappa-B (NF-κB) signaling pathways, thereby promoting p21 protein expression while decreasing lamin B1 protein expression, and finally alleviated oxidative stress-induced cell damage and aging. In a model of rhabdomyosarcoma (RD) cells being infected by enterovirus 71 (EV71) and coxsackievirus B3 (CVB3), the ucMSC-EXO enhanced the expression of interferon-stimulated gene 15 (ISG15) and ISG56 to inhibit enteroviral replication, whereafter reducing the virus-induced proinflammatory factor production. This study provides a promising therapeutic strategy for ucMSC-EXO in anti-oxidative stress and antiviral effects, which provides insight into extending the function of ucMSC-EXO in cell-free therapy.
