background: endometriosis is the presence of endometrial tissue outside of the uterine cavity and is the most common gynecologic disorder in women of reproductive age. we have preliminary evidence that in the presence of a 3-dimensional (3-d) fibrin matrix, human endometrial glands, stroma, and neovascularization can develop in vitro, mimicking the earliest stages of endometriosis. the aim of t...
We have evaluated the degree of MMP-9 and TIMP-1 messenger RNA (mRNA) expressions according to cell types in tumor tissues, and evaluated the implication of balance between the MMP-9 mRNA and the TIMP-1 mRNA expression in liver metastasis using orthotopic-implanted colon cancer in nude mouse, and also in 47 patients with colorectal cancer. The grade of MMP-9 or TIMP-1 mRNA expression was classi...
We have used a c-kit-specific monoclonal antibody, immuno-fluorescence staining and flow fluorocytometry or microscopy analysis to assess the cell surface expression of the c-kit receptor on a panel of non-transformed clones representing different stages of T- and B-lymphocyte development, freshly isolated lymphoid cells from thymus, bone marrow and spleen of young adult C57BL/6 mice and cells ...
Lymphocyte infiltration into epithelial tissues and proinflammatory cytokine release are key steps in autoimmune disease. Although cell-autonomous roles of lymphocytes are well studied in autoimmunity, much less is understood about the stromal factors that dictate immune cell function. Tissue inhibitor of metalloproteinases 3 (TIMP3) controls systemic cytokine bioavailability and sig-naling by ...
background: dendritic cells (dcs) are potent antigen presenting cells for triggering of the immune reaction post transplantation. these cells are centrally involved in the initiation of t cell-dependent immune responses. objective: to compare the level of dc maturation and function in liver transplant recipients with healthy controls. methods: in this study, twelve peripheral blood samples were...
In 1995 and 1997 we proposed that gap junctions between stromal and hematopoietic cells formed by connexin43 (Cx43) determine hematopoiesis. If this were the case, are the critical gap junctions in this regard those between hematopoietic and stromal cells, or those between stromal cells alone? To test the first possibility, we compared hematopoietic repopulating capacity between fetal liver hem...
BACKGROUND Hepatocellular carcinoma (HCC) is considered the 3rd leading cause of death by cancer worldwide with the majority of patients were diagnosed in the late stages. Currently, there is no effective therapy. The selection of an animal model that mimics human cancer is essential for the identification of prognostic/predictive markers, candidate genes underlying cancer induction and the exa...
objectives: periodontal tissue regeneration for treatment of periodontal disease has not yet been mastered in tissue engineering. stem cells, scaffold, and growth factors are the three main basic components of tissue engineering. periodontal ligament (pdl) contains stem cells; however, the number, potency and features of these cells have not yet been understood. this study aimed to isolate and ...
introdution: stroke is one of the most common diseases caused by occlusion or rupture of blood vessels in brain. it brings heavily loads for families and societies. although some new strategies including treatment of tissue plasminogen activator have been applied in the clinic, these methods do not have perfect effect. accordingly, more effective therapeutic strategies need to be developed. thi...
