Schwann cells (SC) which are myelin-forming cells in peripheral nervous system are very useful for the treatment of diseases of peripheral nervous system and central nervous system. However, it is difficult to obtain sufficient large number of SC for clinical use, so alternative cell systems are desired. Using a procedure similar to the one used for(More)
Despite well-studied tumor hypoxia in laboratory, little is known about the association with other pathophysiological events in the clinical view. We investigated the prognostic value of hypoxia-inducible factor-1 alpha (HIF-1alpha) in hepatocellular carcinoma (HCC), and its correlations with inflammation, angiogenesis and MYC oncogene. In a random series(More)
BACKGROUND & AIMS Neutrophil infiltration has been linked to clinical outcome of various cancer types. However, its role in hepatocellular carcinoma (HCC) is unclear. In this study, we investigated prognostic values for intratumoral and peritumoral neutrophils in HCC patients undergoing curative resection. METHODS The expression of CD66b, CD8, TGF-beta,(More)
Human mesenchymal stem cells (MSCs) have been studied and applied extensively because of their ability to self-renew and differentiate into various cell types. Since most human diseases models are murine, mouse MSCs should have been studied in detail. The mdx mouse – a Duchenne muscular dystrophy model – was produced by introducing a point mutation in the(More)
PURPOSE Human leukocyte antigen-G (HLA-G) is a tumor-associated immunosuppressive molecule involved in tumor escape mechanisms. The aim of this study is to elucidate its prognostic significance in hepatocellular carcinoma (HCC). EXPERIMENTAL DESIGN Immunohistochemical staining of HLA-G expression as well as tumor-infiltrating FoxP3+ regulatory (Tregs) and(More)
Although Schwann cell (SC) transplantation can enhance peripheral and central nerve repair experimentally, it is difficult to generate sufficient SC quickly for clinical application. So alternative cell systems for SC are desired. SC-like cells induced from adipose-derived stem cells (ADSC) may be one of the ideal alternative cell systems for SC. However,(More)
Microvessel density (MVD) as an angiogenesis predictor is inefficient per se in cancer prognosis. We evaluated prognostic values of combining intratumoral alpha-smooth muscle actin (α-SMA)-positive stromal cell density and MVD after curative resection in hypervascular hepatocellular carcinoma (HCC) and hypovascular pancreatic cancer (PC). Tissue microarrays(More)
PURPOSE Interleukin (IL)-21 has recently been shown to play a vital role in the development of many autoimmune diseases. Our study is designed to investigate the alteration and possible function of IL-21 in the development of an experimental autoimmune uveitis (EAU) model. METHODS EAU was induced in B10.RIII mice by subcutaneous injection of(More)
BACKGROUND & AIMS Phosphatidylethanolamine-binding protein 1 (PEBP1, also RKIP) plays a pivotal role in cancer by regulating multiple cellular signaling processes and suppressing metastasis in animal models. We examined whether PEBP1 expression in hepatocellular carcinoma (HCC) correlated with the risk of recurrence and survival after resection. METHODS A(More)
Solid pseudopapillary tumor of the pancreas is a rare neoplasm with low malignant potential, which affects predominantly young females. Only approximately 10% to 15% cases of solid pseudopapillary tumors (SPTs) are malignant. We present the case of a 57-year-old woman who developed malignant SPT of the pancreas. Meanwhile, a literature review was carried(More)
