objective(s):the limited homing potential of bone-marrow-derived mesenchymal stem cells (bm-msc) is the key obstacle in msc-based therapy. it is believed that chemokines and chemokine receptor interactions play key roles in cellular processes associated with migration. meanwhile, mscs express a low level of distinct chemokine receptors and they even lose these receptors on their surface after a...

Angiogenesis is vitally important in diabetic wound healing. We had previously demonstrated that a Chinese 2-herb formula (NF3) significantly stimulated angiogenesis of HUVEC in wound healing. However, the molecular mechanism has not yet been elucidated. In line with this, global expression profiling of NF3-treated HUVEC was performed so as to assess the regulatory role of NF3 involved in the u...
Chemokines critically regulate chemotaxis in normal and pathologic states, but there is limited understanding of how multicellular interactions generate gradients needed for cell migration. Previous studies of chemotaxis of CXCR4+ cells toward chemokine CXCL12 suggest the requirement of cells expressing scavenger receptor CXCR7 in a source-sink system. We leveraged an established microfluidic d...
PURPOSE We report a novel analytic method, named intercohort co-analysis or Ican, which aids in the discovery of genes with predictive value for the progression or outcome of diseases from small-size cohorts. We tested this premise in Ewing's sarcoma (ES), a highly metastatic cancer of bone and soft tissues that lacks validated molecular metastasis and prognostic indicators. EXPERIMENTAL DESI...
Transplanted mesenchymal stem cells (MSCs) have been shown to contribute to myocardial repair after myocardial infarction (MI), primarily through production and secretion some growth factors and cytokines related to cell survival and regeneration. Further improvement of the therapeutic potential of MSCs appears to be an attractive strategy for MI treatment. CXC chemokine receptor (CXCR) 7 is th...
Circulating glucocorticoid levels oscillate with a robust circadian rhythm, yet the physiological relevance of this rhythmicity remains unclear. Here, we show that modulation of circadian glucocorticoid oscillation by enhancing its amplitude leads to anxiolytic-like behavior. We observed that mice with adrenal subcapsular cell hyperplasia (SCH), a common histological change in the adrenals, are...
The present study involved the isolation and characterization of canine tumor endothelial cells (TECs) from 2 malignancies. TECs were isolated using magnetic cell sorting following FITC labeling with UEA1 lectin, and they were characterized by measuring genetic and histopathological endothelial markers. Isolated TECs exhibited a cobblestone-like morphology and expressed both vascular endothelia...
OBJECTIVE Although stromal cell-derived factor (SDF)-1αis well known to modulate the mobilization of hematopoietic stem cells and endothelial progenitor cells, its effects on some pre-existing vascular functions remain unknown. We have investigated here the role of SDF-1αsignaling in endothelial barrier function. APPROACH AND RESULTS Treatment with SDF-1α elevated transendothelial electrical ...
