The growth of endometrial cells in ectopic locations (endometriosis) is dependent on the establishment of an adequate blood supply. Neovascularization (angiogenesis) is therefore a vital step toward the progression of this disease. We first revealed the presence of a potent mitogenic activity for human endothelial cells in the culture medium of immortalized(More)
Hydroquinone (HQ), a reactive metabolite of benzene, is known to inhibit mitogen-stimulated activation of both T and B lymphocytes. Despite extensive study, the underlying mechanism for the immunotoxicity of the HQ is not clear. We have previously demonstrated that 1 μmol/L HQ inhibits TNF-induced activation of NFκB in CD4+ T cells, resulting in decreased(More)
In the present study, we differentiated hepatocyte-like cells (HLCs) from human adipose tissue-derived mesenchymal stem cells (AT-MSCs). The hepatic differentiation was confirmed by increases in hepatic proteins or genes, the cytochrome P450 (CYP) activities, albumin secretion, and glycogen storage. To determine the developmental toxic effect of arsanilic(More)
Natural killer (NK) cells play an important role in the innate immune response. Interleukin-18 (IL-18) is a well-known interferon-gamma (IFN-gamma inducing factor, which stimulates immune response in NK and T cells. Sphingosine kinase (SPHK) catalyzes the formation of sphingosine 1-phosphate (S1P), which acts as a second messenger to function as an(More)
