Multifaceted Therapeutic Benefits of Factors Derived From Dental Pulp Stem Cells for Mouse Liver Fibrosis.

Unlabelled: : Chronic liver injury from various causes often results in liver fibrosis (LF). Although the liver possesses endogenous tissue-repairing activities, these can be overcome by sustained inflammation and excessive fibrotic scar formation. Advanced LF leads to irreversible cirrhosis and subsequent liver failure and/or hepatic cancer.

Conditioned Medium from the Stem Cells of Human Exfoliated Deciduous Teeth Ameliorates Experimental Autoimmune Encephalomyelitis.

Multiple sclerosis (MS) is a major neuroinflammatory demyelinating disease of the CNS. Current MS treatments, including immunomodulators and immunosuppressants, do not result in complete remission. Stem cells from human exfoliated deciduous teeth (SHEDs) are mesenchymal stem cells derived from dental pulp.

Conditioned medium from the stem cells of human dental pulp improves cognitive function in a mouse model of Alzheimer's disease.

Alzheimer's disease (AD) is a progressive, neurodegenerative disease characterized by a decline in cognitive abilities and the appearance of β-amyloid plaques in the brain. Although the pathogenic mechanisms associated with AD are not fully understood, activated microglia releasing various neurotoxic factors, including pro-inflammatory cytokines and oxidative stress mediators, appear to play major roles. Here, we investigated the therapeutic benefits of a serum-free conditioned medium (CM) derived from the stem cells of human exfoliated deciduous teeth (SHEDs) in a mouse model of AD.

Lewis y antigen is expressed in oral squamous cell carcinoma cell lines and tissues, but disappears in the invasive regions leading to the enhanced malignant properties irrespective of sialyl-Lewis x.

Expression and implication of carbohydrate antigens in squamous cell carcinomas (SCCs) in oral cavity was examined. In the cell lines, type 2H and Lewis y antigens were markedly expressed. In the tissues from SCC patients and benign disorders, type 2H was highly expressed in hyperplasia (96.

Stem cells from human exfoliated deciduous tooth-derived conditioned medium enhance recovery of focal cerebral ischemia in rats.

Regenerative therapy using stem cells is a promising approach for the treatment of stroke. Recently, we reported that dental pulp stem cells (DPSC) ameliorated ischemic tissue injury in the rat brain and accelerated functional recovery after middle cerebral artery occlusion (MCAO). In this study, we investigated the effects of stem cells from human exfoliated deciduous tooth (SHED)-derived conditioned medium (SHED-CM) on permanent MCAO (pMCAO).

Enhancement of malignant properties of human osteosarcoma cells with disialyl gangliosides GD2/GD3.

The expression and implications of gangliosides in human osteosarcomas have not been systematically analyzed. In this study, we showed that gangliosides GD3 and GD2 are highly expressed in the majority of human osteosarcoma cell lines derived from oral cavity regions. Introduction of GD3 synthase cDNA into a GD3/GD2-negative (GD3/GD2-) human osteosarcoma subline resulted in the establishment of GD3/GD2+ transfectant cells.

Functional activation of Src family kinase yes protein is essential for the enhanced malignant properties of human melanoma cells expressing ganglioside GD3.

The possible roles of Src family kinases in the enhanced malignant properties of melanomas related to GD3 expression were analyzed. Among Src family kinases only Yes, not Fyn or Src, was functionally involved in the increased cell proliferation and invasion of GD3-expressing transfectant cells (GD3+). Yes was located upstream of p130Cas and paxillin and at an equivalent level to focal adhesion kinase.

Dental pulp-derived CD31⁻/CD146⁻ side population stem/progenitor cells enhance recovery of focal cerebral ischemia in rats.

Regenerative therapy using stem cells is a promising approach for the treatment of stroke. Recently, we reported that CD31⁻/CD146⁻ side population (SP) cells from porcine dental pulp exhibit highly vasculogenic potential in hindlimb ischemia. In this study, we investigated the influence of CD31⁻/CD146⁻ SP cells after transient middle cerebral artery occlusion (TMCAO).

Stability of a locking plate and self-drilling screws as orthodontic skeletal anchorage in the maxilla: a retrospective study.

Purpose: The aim of this retrospective study was to determine the success rate of an orthodontic skeletal anchorage system consisting of a locking plate and 2 self-drilling screws to intrude the upper molars and detect factors that contribute to its stability.

Patients And Methods: The subjects were 32 orthodontic and generally healthy patients who had skeletal anchorage plates placed supraperiosteally and unilaterally or bilaterally. The anchorage plate was considered successful if the plate remained stable throughout the period of intrusion of the upper molar without any movement, persistent pain, or infection and was then retrieved without difficulty.

Downregulation of the beta1,3- galactosyltransferase gene in tonsillar B lymphocytes and aberrant lectin bindings to tonsillar IgA as a pathogenesis of IgA nephropathy.

IgA is a glycoprotein with multiple O-glycans. Under-O-glycosylation of the hinge in IgA in patients with IgA nephropathy (IgAN) is reported. The development of IgAN is frequently preceded by episodes of upper respiratory tract infections such as tonsillitis.

STAT1 is involved in the pathogenesis of murine allergic rhinitis.

Background: Signal transducer and activator of transcription (STAT) 1 signaling pathway mediates biological functions of interferon (IFN) gamma, which is a key cytokine-regulating T helper 1 (Thl) differentiation. Although constitutive activation of STAT1 has been reported in the airway epithelium of patients with chronic asthma, its in vivo role in the pathogenesis of allergic rhinitis is not clear. We determined the role of STAT1 in the pathogenesis of allergic rhinitis in vivo using STAT1 gene-deficient (STAT1-/-) mice and a murine model of Schistosoma mansoni egg antigen (SEA)-induced allergic rhinitis.
