BACKGROUND The synovial tissues with temporomandibular disorders (TMDs) often show chronic inflammatory changes and the synovial cells participate in the pathogenic processes of TMDs. The synovial membrane is composed of a synovial lining layer and a connective sublining layer. The synovial lining layer is made up of two kinds of cells: macrophage-like type(More)
BACKGROUND AND OBJECTIVE The gingival epithelium is the physiologically important interface between the bacterially colonized gingival sulcus and periodontal soft and mineralized connective tissues, requiring protection from exposure to bacteria and their products. However, of the three epithelia comprising the gingival epithelium, the junctional epithelium(More)
BACKGROUND AND OBJECTIVE It has been reported that retinoic acid disintegrates the desmosome formation of squamous epithelium, resulting in inhibition of stratification. In contrast, it is not known whether retinoic acid influences the integration of tight junctions. Therefore, our objective of this study is to disclose effects of retinoic acid on the(More)
Differential expression of members of the connexin (Cx) gap junction multigene family permits formation of gap junctions with the varied physiological properties required by different tissues. The aim of this study was to characterize connexin expression and the influence of all-trans-retinoic acid (RA) in mouse gingival epithelial cells (GE1). The cells(More)
BACKGROUND Although it is known that retinoic acid (RA) regulates the cellular differentiation of skin keratinocytes, the effects of RA on the anchoring junction have not been clarified. The effects of all-trans RA on cell-cell and cell-matrix connections of gingival epithelial (GE)1 cells in a multilayered culture were investigated. METHODS(More)
BACKGROUND An in vitro cell culture system of dental epithelium is useful for the investigations of cellular differentiation and function of ameloblast in amelogenesis and of regenerative therapy in human tooth. However, there have been no immortalized human dental epithelial ameloblastic-lineage cell lines, which proliferate indefinitely and additionally(More)
The objective of this study was to find the sites with proliferative activity in the human gingival epithelium, where stem cells are likely to exist. Gingival tissues were excised from 16 adult patients and immunohistochemically examined for the presence of bromodeoxyuridine (BrdU)-incorporating, p63- and low affinity nerve growth factor receptor(More)
A 24-year-old woman was admitted to our hospital on November 2, 1989 for investigation and treatment of abnormal shadows detected in her routine chest radiograph on July 19, 1989. The chest X-ray film on admission showed diffuse infiltrative shadows in the peripheral regions of the bilateral middle and lower lung fields. In addition centrilobular shadows in(More)
A myelo dysplastic syndrome (MDS), refractory anemia with excess of blasts (RAEB), that occurred in a patient with small cell lung cancer (SCLC) during a period of complete response (CR) was reported. A 66-year-old female patient was diagnosed as SCLC in March, 1985. Induction chemotherapy (CDDP, ADM, VCR, VP-16) achieved CR in May, 1985. She had received(More)
