The aim of our study was to elucidate the effect of tacrolimus (FK506) and of C-X-C chemokine receptor type 4 (CXCR4), which is a receptor specific to the stromal cell-derived factor-1α (SDF‑1α), on growth and metastasis of hepatocellular carcinoma (HCC). Following treatment with different concentrations of FK506, AMD3100 or normal saline (NS), the proliferation of Morris rat hepatoma 3924A (MH...

BACKGROUND The production of chemokines by tissue resident cells during inflammation is considered one of the main mechanisms involved in the formation of inflammatory infiltrates. Fibroblasts are the main resident cell type in gingival and periodontal ligament tissues, and their ability to produce chemokine stromal cell-derived factor 1 alpha (SDF-1α) and its receptor CXCR4 under stimulation b...

BACKGROUND Cardiac progenitor cells (CPCs) have been proven suitable for stem cell therapy after myocardial infarction, especially c-kit(+)CPCs. CPCs marker c-kit and its ligand, the stem cell factor (SCF), are linked as c-kit/SCF axis, which is associated with the functions of proliferation and differentiation. In our previous study, we found that stromal cell-derived factor-1α (SDF-1α) could ...

background: stem cell factor (scf) is a transcriptional factor which plays crucial roles in normal proliferation, differentiation and survival in a range of stem cells. objective: the aim of the present study was to examine the proliferation effect of different concentrations of scf on expansion of human endometrial cd146+ cells. materials and methods: in this experimental study, total populati...

Increased plasticity, migratory and immunosuppressive abilities characterize mesenchymal stromal cells (MSC) which enable them to be active participants in the development of hypoxic solid tumours. Our understanding of the oncogenic adaptation of MSC to hypoxia however lacks the identification and characterization of specific biomarkers. In this study, we assessed the hypoxic regulation of 3BP2...

background: the present study investigated the functional maturity of oligodendrocyte derived from rat bone marrow stromal cells (bmsc). methods: the bmsc were isolated from female sprague-dawley rats and evaluated for different markers, such as fibronectin, cd106, cd90, oct-4 and cd45. transdifferentiation of olc from bmsc was obtained by exposing the bmsc to dmso and 1 µm all-trans-retinoic a...

OBJECTIVE Kawasaki disease (KD) is the most common cause of acute vasculitis and acquired cardiac disease among US children. We have previously shown that both TLR2/MyD88 and interleukin (IL)-1β signaling are required for the Lactobacillus casei cell wall extract-induced KD vasculitis mouse model. The objectives of this study were to investigate the cellular origins of IL-1 production, the role...
