Little is known about the architecture of cellular microenvironments that support stem and precursor cells during tissue development. Although adult stem cell niches are organized by specialized supporting cells, in the developing cerebral cortex, neural stem/precursor cells reside in a neurogenic niche lacking distinct supporting cells. Here, we find that(More)
CXC chemokine recepter-4 (CXCR4) and its ligand, stromal cell-derived factor-1alpha (SDF-1alpha) have been implicated in the organ-specific metastasis of several malignancies. Hca-F and its syngeneic cell line Hca-P are mouse hepatocarcinoma cell lines with high and low potential of lymphatic metastasis, respectively. Previous studies showed that the(More)
Livin, X-linked inhibitor of apoptosis (XIAP), and Survivin are three well-known inhibitors of apoptosis almost exclusively over-expressed in cancer cells and are considered potent targets for cancer treatment. In the present study, we found that Livin, XIAP, and Survivin were simultaneously expressed in bladder cancer cells. We speculated that Livin, XIAP,(More)
Individualized treatment is a promising clinical strategy for lung cancer, and drug sensitivity testing is fundamental to this scheme. We aimed to develop an effective drug sensitivity test platform to support individualized treatment. We designed a microfluidic chip-based, three-dimensional (3D) co-culture drug sensitivity test platform. A mono-lung cancer(More)
During cerebral cortical development, neural precursor-precursor interactions in the ventricular zone neurogenic niche coordinate signaling pathways that regulate proliferation and differentiation. Previous studies with shRNA knockdown approaches indicated that N-cadherin adhesion between cortical precursors regulates β-catenin signaling, but the underlying(More)
Extracellular matrix metalloproteinase inducer (EMMPRIN, CD147), which is a plasma membrane glycoprotein enriched on the surface of many malignant tumors promotes adhesion, invasion and metastasis of tumor cells. In addition, tumor-associated CD147 also induces vascular endothelial growth factors (VEGFs) expression. To investigate the possible role of CD147(More)
CD147 which is a regulator of matrix metalloproteinase (MMP) production on the surface of many malignant tumor cells, shows a highly specific association with caveolin-1 (Cav-1). As a result of heterogeneous N-glycosylation, CD147 exists in both highly glycosylated form, HG-CD147 ( approximately 40-60kDa) and lowly glycosylated form, LG-CD147 ((More)
β-elemene, a natural drug extracted from Curcuma wenyujin, strongly inhibits glioblastoma growth. However, the mechanism of β-elemene antitumor action remains unclear. Glia maturation factor β (GMFβ) regulates cellular growth, fission, differentiation and apoptosis. It has been reported that overexpression of GMFβ inhibits the growth of glioblastoma cells(More)
fatty acids are considered to be effective components to promote wound healing and Lucilia sericata larvae are applied clinically to treat intractable wounds. We aimed to investigat the effect of fatty acid extracts from dried Lucilia sericata larvae on murine cutaneuous wound healing as well as angiogenesis. On day 7 and 10 after murine acute excision(More)
Matrix metalloproteinase-11 (MMP-11) belongs to the particular member of MMP family, a group of zinc-dependent endopeptidases involved in tumor progression, invasion and metastasis. MMP-11 is strongly expressed in tumor cells and stromal fibroblasts located in the immediate vicinity of tumor. This study investigated the possible role of MMP-11 expression in(More)
