Significant endeavor has been applied to identify functional therapeutic targets in glioblastoma (GBM) to halt the growth of this aggressive cancer. We show that the receptor tyrosine kinase EphA3 is frequently overexpressed in GBM and, in particular, in the most aggressive mesenchymal subtype. Importantly, EphA3 is highly expressed on the tumor-initiating(More)
Use of flow cytometry to detect pluripotency markers on or in human embryonic stem cells (hESCs) is a powerful analytical tool. However, current staining methodologies for high-content analysis of large numbers of samples utilize large quantities of primary and secondary antibodies, are time consuming, and may suffer from sample-to-sample variability. To(More)
It is widely acknowledged that neurogenesis occurs in the adult hippocampus under normal conditions and that the rate can be regulated by environmental factors, including antidepressant drugs, with concomitant effects on behaviour. Using a quick and sensitive flow cytometry method that can assess changes in the number of bromodeoxyuridine (BrdU)-positive(More)
Individual tumour cells display diverse functional behaviours in terms of proliferation rate, cell-cell interactions, metastatic potential and sensitivity to therapy. Moreover, sequencing studies have demonstrated surprising levels of genetic diversity between individual patient tumours of the same type. Tumour heterogeneity presents a significant(More)
Inflammasomes are large protein complexes induced by a wide range of microbial, stress, and environmental stimuli that function to induce cell death and inflammatory cytokine processing. Formation of an inflammasome involves dramatic relocalization of the inflammasome adapter protein apoptosis-associated speck-like protein containing a caspase recruitment(More)
Brain cancer research has been hampered by a paucity of viable clinical tissue of sufficient quality and quantity for experimental research. This has driven researchers to rely heavily on long term cultured cells which no longer represent the cancers from which they were derived. Resection of brain tumors, particularly at the interface between normal and(More)
The activity of neural precursor cells in the adult hippocampus is regulated by various stimuli; however, whether these stimuli regulate the same or different precursor populations remains unknown. Here, we developed a novel cell-sorting protocol that allows the purification to homogeneity of neurosphere-forming neural precursors from the adult mouse(More)
Cells resembling bone marrow mesenchymal stem cells (MSC) have been isolated from many organs but their functional relationships have not been thoroughly examined. Here we compared the immunophenotype, gene expression, multipotency and immunosuppressive potential of MSC-like colony-forming cells from adult murine bone marrow (bmMSC), kidney (kCFU-F) and(More)
The receptor-generated signals that are responsible for driving the cell cycle are incompletely characterised in mammalian cells. It is clear, however, that the cellular messenger systems that stimulate DNA synthesis and mitosis are separable. These are interwoven with biochemical checkpoints that ensure that processes, such as chromosomal replication and(More)
Implantation of sterile foreign objects in the peritoneal cavity of an animal initiates an inflammatory response and results in encapsulation of the objects by bone marrow-derived cells. Over time, a multilayered tissue capsule develops with abundant myofibroblasts embedded in extracellular matrix. The present study used the transgenic MacGreen mouse to(More)
