Objective To explore the possible mechanism of umbilical cord mesenchymal stem cells (UCMSCs) regulating milk protein synthesis in bovine mammary gland epithelial cells (BMECs). Methods UCMSCs and BMECs were co-cultured by double-chamber Transwell(TM), and other BMECs were cultured alone as a control group. Insulin like growth factor 1 receptor (IGF-1R) inhibitor AG1024 was used to treat cells. IGF-1, β casein (CSN2) and κ casein (CSN3) content in the supernatants were determined by ELISA; the relative expression abundance of Janus kinase and signal transducer and activator of transcription factor (JAK/STAT) signaling pathway-related genes were detected by quantitative real-time PCR (qRT-PCR); and after the cells were treated with JAK2 signal blocker AG490, qRT-PCR was performed to test the relative expression abundance of CSN2 and CSN3 mRNAs...

Human umbilical cord-derived mesenchymal stem cells (UC-MSCs) are considered an attractive cell source for tissue regeneration. However, environmental oxidative stress can trigger premature senescence in MSCs and thus compromises their regenerative potential. Extracellular matrix (ECM) derived from MSCs has been shown to facilitate cell proliferation and multilineage differentiation. This investigation evaluated the effect of cell-deposited decellularized ECM (DECM) on oxidative stress-induced premature senescence in UC-MSCs...

The aberrant generation or activation of T follicular helper (Tfh) cells contributes to the pathogenesis of systemic lupus erythematosus (SLE), yet little is known about how these cells are regulated. In this study, we demonstrated that the frequency of Tfh cells was increased in lupus-prone B6.MRL-<em>Fas<sup>lpr</sup></em> (B6.<em>lpr</em>) mice and positively correlated to plasma cell proportions and serum total IgG as well as anti-dsDNA antibody levels. Transplantation of human umbilical cord mesenchymal stem cells (UC-MSCs) ameliorated lupus symptoms in B6...

Several cell therapies have been explored as novel therapeutic strategies for neonatal encephalopathy because the benefits of current treatments are limited. We previously reported that intravenous administration of human umbilical cord blood (hUCB) CD34+ cells (hematopoietic stem cells/endothelial progenitor cells) at 48 h after insult exerts therapeutic effects in neonatal mice with stroke, i.e., permanent middle cerebral artery occlusion. Although neonatal stroke and hypoxic-ischemic encephalopathy (HIE) are grouped under the term "neonatal encephalopathy," their pathogenesis differs...

Cell-based approaches, including hepatocyte transplantation and tissue-engineered livers, offer promising alternatives and are expected to help support patients with liver diseases until liver transplantation or recovery via regeneration of the damaged liver. However, the success of cell therapies remains dependent on how well the cells are accepted after transplantation and is directly related to their degree of immunogenicity. In this study, hepatic differentiation of human umbilical cord mesenchymal stem cells (hUC-MSCs) was induced in the traditional monolayer (2D) culture and newly established three-dimensional (3D) aggregation culture with the porcine decellularized liver scaffold (DLS) system (3D-DLS)...

The use of stem or progenitor cells from bone marrow, or peripheral or umbilical cord blood is becoming more common for treatment of diabetic foot problems. These cells promote neovascularization by angiogenic factors and they promote epithelium formation by stimulating cell replication and migration under certain pathological conditions. We investigated the role of CD34 + stem cells from human umbilical cord blood in wound healing using a rat model. Rats were randomly divided into a control group and two groups with diabetes induced by a single dose of 55 mg/kg intraperitoneal streptozocin...

Redox homeostasis plays a crucial role in the regulation of self-renewal and differentiation of stem cells. However, the behavioral actions of mesenchymal stem cells in redox imbalance state remain elusive. In the present study, the effect of redox imbalance that was induced by either hydrogen peroxide (H2O2) or ascorbic acid on human cardiac-resident (hC-MSCs) and non-resident (umbilical cord) mesenchymal stem cells (hUC-MSCs) was evaluated. Both cells were sensitive and responsive when exposed to either H2O2 or ascorbic acid at a concentration of 400 µmol/L...

Improving the immunomodulatory efficacy of mesenchymal stem cells (MSCs) through pretreatment with pro-inflammatory cytokines is an evolving field of investigation. However, the underlying mechanisms have not been fully clarified. Here, we pretreated human umbilical cord-derived MSCs with interleukin-1β (IL-1β) and evaluated their therapeutic effects in a cecal ligation and puncture (CLP)-induced sepsis model. We found that systemic administration of IL-1β-pretreated MSCs (βMSCs) ameliorated the symptoms of murine sepsis more effectively and increased the survival rate compared with naïve MSCs...

Exosomes are small biological membrane vesicles secreted by various cells, including mesenchymal stem cells (MSCs). We previously reported that MSC-derived exosomes (MSC-Ex) can elicit hepatoprotective effects against toxicant-induced injury. However, the success of MSC-Ex-based therapy for treatment of liver diseases and the underlying mechanisms have not been well characterized. We used human umbilical cord MSC-derived exosome (hucMSC-Ex) administrated by tail vein or oral gavage at different doses and, in engrafted liver mouse models, noted antioxidant and anti-apoptotic effects and rescue from liver failure...

BACKGROUND AND PURPOSE: Neonatal hypoxic-ischemic encephalopathy (HIE) is one of the leading causes of neurological handicap in developing countries. Human umbilical cord blood (hUCB) CD34-positive (CD34⁺) stem cells exhibit the potential for neural repair. We tested the hypothesis that hUCB CD34⁺ stem cells and other cell types [leukocytes and nucleated red blood cells (NRBCs)] that are up-regulated during the acute stage of perinatal asphyxia (PA) could play a role in the early prediction of the occurrence, severity, and mortality of HIE...

There has been recently been increased interest in the plasticity of human umbilical cord mesenchymal stem cells (UMSCs) and their potential in the treatment of neurological disorders. In this study, UMSCs were transdifferentiated into neural stem-like cells (uNSCL), these cells grow in neurosphere-like structures and express high levels of NSCs markers. Epigenetics-related gene screening was here used to assess the relationship between E1A-like inhibitor of differentiation 3 (EID3), a p300 inhibitor, and DNA methyltransferase 3 A (DNMT3A) during the transdifferentiation of UMSCs into uNSCL in vitro...

Liposomes are used for encapsulation of the active compounds in different therapies, with the increasing frequency. The important areas of clinical applications of liposomes are cancer targeted treatment, antibiotic delivery or regenerative medicine. The liposomes can transfer both hydrophilic and hydrophobic compounds and have the lipid bilayer which imitates the cell membrane. Liposomes additionally may extend half-live period of drugs and protect them against the elimination in different ways, such as phagocytosis, enzymatic cleavage or exclusion by detoxification...

INTRODUCTION: Erectile dysfunction (ED) worsens in men with diabetes. Human umbilical cord blood (HUCB), because of its widespread availability and low immunogenicity, is a valuable source for stem cell-based therapies. AIM: To determine the effect of intracavernous injection of HUCB mononuclear cells (MNCs) on ED in rats with diabetes induced by streptozotocin. METHODS: Thirty adult male Sprague-Dawley rats were equally divided into three groups: (i) control, (ii) diabetes induced by streptozotocin (35 mg/kg intravenously for 8 weeks), and (iii) diabetic rats treated with MNCs (1 × 10(6) cells by intracavernosal injection)...

Articular cartilage is an avascular, alymphatic, and aneural system with very low regeneration potential because of its limited capacity for self-repair. Mesenchymal stem cells (MSCs) are the preferred choice for cell-based therapies. Glycogen synthase kinase 3 (GSK-3) inhibitors are compounds that can induce the Wnt signaling pathway, which is involved in chondrogenesis and cartilage development. Here, we investigated the influence of lithium chloride (LiCl) and SB216763 synergistically with TGF-β3 on chondrogenic differentiation in human mesenchymal stem cells derived from Wharton's jelly tissue (hWJ-MSCs)...
