Activation of hepatic stellate cells (HSCs) plays a crucial role in liver fibrogenesis. armepavine (Arm, C19H23O3N), an active compound from Nelumbo nucifera, has been shown to exert immunosuppressive effects on T lymphocytes and on lupus nephritic mice. The aim of this study was to investigate whether Arm could exert anti-hepatic fibrogenic effects in(More)
OBJECTIVE Amniotic fluid mesenchymal stem cells (MSCs) have the potential to differentiate into neuronal stem cells in vitro. We evaluated using amniotic fluid MSCs to support or enhance the ability of the injured sciatic nerve to cross a nerve gap. MATERIALS AND METHODS We created a 5 mm nerve defect in Sprague Dawley rats. One group received therapy(More)
The protective effect of combination therapy with valsartan and aliskiren against renal fibrosis remains to be defined. This study was undertaken to examine the protective effects of the combination of valsartan and aliskiren against renal fibrosis induced by unilateral ureteral obstruction (UUO). Combination therapy with valsartan (15 mg·kg(-1)·day(-1))(More)
BACKGROUND Anti-inflammation strategies are one of the proposed therapeutic approaches to hepatic fibrosis. Tetrandrine (C(38)H(42)O(8)N(2), molecular weight: 622; Tet), an alkaloid isolated from the Chinese medicinal herb Stephania tetrandra, has been shown to exert anti-inflammatory activity in pulmonary diseases. The purpose of the present study was to(More)
The purposes of this study were to examine technical details in deriving and maintaining rabbit embryonic stem (rES) cell lines and to analyze their characteristics. When STO cells were used as feeder cells, no rES cell lines were established using either intact blastocysts or inner cell masses (ICMs). On the mouse embryonic fibroblasts (MEF) feeder, rES(More)
We investigated the individual and combined effects of leukemia inhibitory factor (LIF) and basic fibroblast growth factor 2 (bFGF2) on the derivation and maintenance of rabbit embryonic stem cell lines isolated from parthenogenetic activated embryos (p-rES). First, we demonstrated that p-rES cell lines can be prevented from differentiation via LIF (STAT3)(More)
OBJECTIVES Heart failure is associated with increased plasma norepinephrine (NE) and endothelial apoptosis. Recent reports have suggested that endothelial dysfunction is an important target for future therapies of heart failure. However, whether NE can induce endothelial apoptosis and its mechanism remains unknown. METHODS Endothelial cells from neonatal(More)
OBJECTIVE Norepinephrine (NE)-induced apoptosis in cardiomyocytes is an important cause of heart failure. Previous studies revealed that reactive oxygen species (ROS) are involved in apoptosis. Tumor necrosis factor-alpha (TNF), a well-known mediator that stimulates apoptosis, is not only produced by macrophages but also by cardiomyocytes. Until now, the(More)
Fibrosis-related changes in livers of cirrhotic rats induced by dimethylnitrosamine (DMN) have not yet been fully clarified. The aim of this study was to investigate changes in molecular and biochemical markers in DMN-intoxicated rats. DMN was administered to Sprague-Dawley rats for 2 and 5 weeks to induce different degrees of hepatic fibrosis. Liver(More)
The homeobox gene families play important roles in the transcriptional regulation of gene expression prior to and during embryo development. To identify novel homeobox genes expressed in early embryonic development, we conducted a degenerated oligonucleotide polymerase chain reaction (PCR) to screen a mouse embryonic stem (ES) cell cDNA library. A novel(More)
