There have been intensive studies on the differentiation of endothelial progenitor cells (EPCs) into endothelial cells. We investigated the endothelial differentiation of placenta-derived multipotent cells (PDMCs), a population of CD34(-)/CD133(-)/Flk-1(-) cells. PDMCs were cultured in basal media or media containing endothelial growth factors (EGM),(More)
To study the roles of anisotropic cell morphology and directionality of mechanical force in apoptosis, the spreading of human umbilical vein endothelial cells (HUVECs) was constrained by growing on micropatterned (MP) strips of fibronectin (FN, 20 microg/cm2) with widths of 15, 30, and 60 microm on silicone membrane. Cells on 30- and 60-microm strips, like(More)
Flow patterns in blood vessels contribute to focal distribution of atherosclerosis; the underlying mechanotransduction pathways remain to be investigated. We demonstrate that different flow patterns elicit distinct responses of Krüppel-like factor-2 (KLF2) in endothelial cells (ECs) in vitro and in vivo. While pulsatile flow with a significant forward(More)
Discoidin domain receptor 1 (DDR1) promotes E-cadherin-mediated adhesion. The underlying mechanism and its significance, however, have not been elucidated. Here we show that DDR1 overexpression augmented, whereas dominant negative mutant (DN-DDR1) or knockdown of DDR1 inhibited E-cadherin localized in cell-cell junctions in epithelial cells. DDR1 changed(More)
Recent studies have shown that use of nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with an increased risk of myocardial infarction. To explore whether NSAIDs may induce endothelial apoptosis and thereby enhance atherothrombosis, we treated human umbilical vein endothelial cells (HUVECs) with sulindac sulfide (SUL), indomethacin (IND), aspirin(More)
Intradermal adipose tissue plays an essential role for hair follicles (HFs) regeneration by regulating hair cycles. However, the effect of reconstruction of HFs and the involvement of adipose-related cells are poorly understood. We investigated assembly strategies for the interactions of dermal papilla (DP) cells with adipose-derived stem cells (ASCs) in(More)
OBJECTIVES To study the presence of lower urinary tract symptoms and parameters of uroflowmetry in women with type 2 diabetes mellitus with and without bladder dysfunction versus healthy controls. METHODS After eliminating the possible confounders that might cause bladder dysfunction, 182 female patients at a diabetic clinic were evaluated by the American(More)
PURPOSE We studied bladder motor dysfunction and searched for markers of neurogenic and myogenic alterations among fructose fed rats with or without abnormal voiding behavior. MATERIALS AND METHODS Female Wistar rats were fed with a fructose rich diet (60%) or a normal diet for 6 months. Based on cystometry and voiding behavior the fructose fed rats were(More)
We investigated the effects of oscillatory flow in regulating the gene expressions of type I collagen (COL1, the main component of human bone tissues) and osteopontin (OPN, the key gene for calcium deposition) in human osteoblast-like (MG-63) cells, and the roles of mitogen-activated protein kinases (MAPKs) in this regulation. The cells were subjected to(More)
RATIONALE Hyperhomocysteinemia contributes to vascular dysfunction and risks of cardiovascular diseases. Stromal cell-derived factor (SDF)-1, a chemokine expressed by endothelial cells (ECs), is highly expressed in advanced atherosclerotic lesions. The interplays among homocysteine, chemokines, and shear stress in regulating vascular endothelial function(More)
