Cellular senescence is a stress response that is characterized by a stable cellular growth arrest, which is important for many physiological and pathological processes, such as cancer and ageing. Recently, senescence has also been implicated in tissue repair and regeneration. Therefore, it has become increasingly critical to identify senescent cells in vivo. Senescence-associated β-galactosidase (SA-β-Gal) assay is the most widely used assay to detect senescent cells both in culture and in vivo. This assay is based on the increased lysosomal contents in the senescent cells, which allows the histochemical detection of lysosomal β-galactosidase activity at suboptimum pH (6 or 5...

Spinal cord injury (SCI) is an incurable disease causing an ischemic environment and functional defect, thus a new therapeutic approach is needed for SCI treatment. Vascular endothelial growth factor (VEGF) is a potent therapeutic gene to treat SCI via angiogenesis and neuroprotection, and both tissue-specific gene expression and high gene delivery efficiency are important for successful gene therapy. Here we design the hypoxia/neuron dual-specific gene expression system (pEpo-NSE) and efficient gene delivery platform can be achieved by the combination ex vivo gene therapy with erythropoietin (Epo) enhancer, neuron-specific enolase (NSE) promoter and neural stem cells (NSCs)...

Microvascular injury initiates the pathogenesis of radiation enteropathy. As previously demonstrated, the secretome from mesenchymal stem cells contains various angiogenic cytokines that exhibited therapeutic potential for ischemic lesions. As such, the present study aimed to investigate whether cytokines derived from mesenchymal stem cells can repair endothelial injuries from irradiated intestine. Here, serum-free medium was conditioned by human adipose-derived mesenchymal stem cells, and we found that there were several angiogenic cytokines in the medium, including IL-8, angiogenin, HGF and VEGF...

Acute lung injury (ALI) is one of the most common clinical critical illnesses. Its severe stage is acute respiratory distress syndrome (ARDS), characterized by rapid onset and high mortality. There is no effective treatment. Based on many preclinical studies, mesenchymal stem cells (MSCs) have great potential as a therapeutic strategy for ALI, clinical trials are underway, and studies on the therapeutic effects of MSCs progressively deep into the molecular mechanism and continue to make new progress. However, the use of MSCs, their specific methods and risks, especially on the risk of iatrogenic tumor formation remains unresolved...

Reduced muscle activity leads to muscle atrophy and function loss in patients and animal models. Satellite cells (SCs) are postnatal muscle stem cells that play a pivotal role in skeletal muscle regeneration following injury. The regenerative potential, satellite cell numbers, and markers during recovery following immobilization of the hindlimb for seven days were explored. In mice exposed to seven days of hindlimb immobilization, in those exposed to recovery (seven days, splint removal), and in contralateral control muscles, muscle precursor cells were isolated from all hindlimb muscles (fluorescence-activated cell sorting, FACS), and SCs and muscle regeneration were identified using immunofluorescence (gastrocnemius and soleus) and electron microscopy (EM, gastrocnemius)...

BACKGROUND Neural stem cells are reported to exist in the hippocampus of adult mammals and are important sources of neurons for repair. The Notch1 signaling pathway is considered as one of the important regulators of neural stem cells, but its role in adult brains is unclear. We aimed to describe the role of Notch1 signaling in the adult rat hippocampus after traumatic brain injury. MATERIAL AND METHODS The model rats were randomly divided into 4 groups as follows: sham, sham-TBI, sham-Ad-TBI, and NICD-Ad-TBI...

Studies have demonstrated that microvesicles (MVs) derived from human Wharton's Jelly mesenchymal stromal cells (hWJMSCs) could ameliorate renal ischemia/reperfusion injury (IRI), however, the underlying mechanisms were not clear yet. Here, MVs were isolated and injected intravenously into rats immediately after ischemia of the left kidney, and Erk1/2 activator HGF or inhibitor U0126 was administrated, respectively. Tubular cell proliferation and apoptosis were identified by Ki67 or TUNEL immunostaining. Masson's tri-chrome straining and alpha-smooth muscle actin (α -SMA) staining were used for assessing renal fibrosis...

Myogenesis is a highly orchestrated, complex developmental process by which cell lineages that are mesodermal in origin generate differentiated multinucleate muscle cells as a final product. Considerable insight into the process of myogenesis has been obtained for the embryonic development of the larval muscles of Drosophila. More recently, the postembryonic development of the muscles of the adult fly has become a focus of experimental investigation of myogenesis since specific flight muscles of the fly manifest remarkable similarities to vertebrate muscles in their development and organization...

BACKGROUND: Using kidneys from deceased donors is an available strategy to meet the growing need of grafts. However, higher incidences of delayed graft function (DGF) and acute rejection exert adverse effects on graft outcomes. Since ischemia-reperfusion injury (IRI) and ongoing process of immune response to grafts are the major causes of DGF and acute rejection, the optimal induction intervention should possess capacities of both repairing renal structure injury and suppressing immune response simultaneously...

Autoimmune hepatitis is a chronic inflammatory disease in the liver with potential to the development of liver fibrosis. Recent evidences suggest that bone marrow derived mesenchymal stem cells (BMSCs) may exert its therapeutic activity through exosomes. Moreover, miR-223 is highly expressed in BMSCs and plays an important role in autoimmune diseases. Therefore, in this study, hepatoprotective role of BMSCs and miR-223 was investigated in both mice and hepatocytes. Liver antigen S100 was used to establish autoimmune hepatitis model in mice while LPS and ATP were used to establish cell injury model in hepatocyte...

Growing evidence that cell-based therapies can improve recovery outcome in spinal cord injury (SCI) models substantiates their application for treatment of human with SCI. To address the effectiveness of these stem cells, potential candidates should be evaluated in proper SCI platform that allows direct real-time monitoring. In this study, the role of epidermal neural crest stem cells (EPI-NCSCs) was elucidated in an ex vivo model of SCI and valproic acid (VPA) was administered to ameliorate the inhospitable context of injury for grafted EPI-NCSCs...

Myelosuppression is the most common complication of chemotherapy. Decline of self-renewal capacity and stress-induced premature senescence (SIPS) of hematopoietic stem cells (HSCs) induced by chemotherapeutic agents may be the cause of long-term myelosuppression after chemotherapy. Whether the mechanism of SIPS of hematopoietic cells relates to chemotherapeutic injury occurred in hematopoietic microenvironment (HM) is still not well elucidated. This study explored the protective effect of Angelica sinensis polysaccharide (ASP), an acetone extract polysaccharide found as the major effective ingredients of a traditional Chinese medicinal herb named Chinese Angelica (Dong Quai), on oxidative damage of homo sapiens bone marrow/stroma cell line (HS-5) caused by 5-fluorouracil (5-FU), and the effect of ASP relieving oxidative stress in HM on SIPS of hematopoietic cells...

Craniomaxillofacial injuries produce complex wound environments involving various tissue types and treatment strategies. In a clinical setting, care is taken to properly irrigate and stabilize the injury, while grafts are molded in an attempt to maintain physiological functionality and cosmesis. This often requires multiple surgeries and grafts leading to added discomfort, pain and financial burden. Many of these injuries can lead to disfigurement and resultant loss of system function including mastication, respiration, and articulation, and these can lead to acute and long-term psychological impact on the patient...

RATIONALE: Burn injuries represent one of the major worldwide public health problems causing more severe physiological stress than other traumas. Effective treatment of burn injuries is mandatory to prevent the numerous life-threatening complications and possible disabilities. Stem cells, a population of multipotent cells retaining the properties of self-renewal and differentiation, are the main player in tissue regeneration after major trauma. Thus, they are thought to play a key role in wound healing inducing efficient and physiological skin regeneration...

Adult neurogenesis, a complex process by which stem cells in the hippocampal brain region differentiate and proliferate into new neurons and other resident brain cells, is known to be affected by many intrinsic and extrinsic factors, including diet. Neurogenesis plays a critical role in neural plasticity, brain homeostasis, and maintenance in the central nervous system and is a crucial factor in preserving the cognitive function and repair of damaged brain cells affected by aging and brain disorders. Intrinsic factors such as aging, neuroinflammation, oxidative stress, and brain injury, as well as lifestyle factors such as high-fat and high-sugar diets and alcohol and opioid addiction, negatively affect adult neurogenesis...

BACKGROUND: Radiation exposure poses a significant threat to public health. Hematopoietic injury is one of the major manifestations of acute radiation sickness. Protection and/or mitigation of hematopoietic stem cells (HSCs) from radiation injury is an important goal in the development of medical countermeasure agents (MCM). We recently identified thioredoxin (TXN) as a novel molecule that has marked protective and proliferative effects on HSCs. In the current study, we investigated the effectiveness of TXN in rescuing mice from a lethal dose of total body radiation (TBI) and in enhancing hematopoietic reconstitution following a lethal dose of irradiation...

BACKGROUND: Growing numbers of allogeneic stem cell transplants (HSCT) and improved post-transplant care have led to an increase of individuals with chronic graft versus host disease (cGVHD). Although cGVHD leads to functional impairment for many, there is limited literature regarding the benefits of acute inpatient rehabilitation for cGVHD patients. OBJECTIVE: To assess Functional Independence Measure (FIM) outcomes of cGVHD patients during acute inpatient rehabilitation, and to compare inpatient rehabilitation outcomes to burn patients, a rehabilitation patient population with similar co-morbidities...
