Transgenic GFAP-, NES-, and SYN- CRE mice were injected with a lenti-viral construct containing a floxed RFP directly upstream of a cassette containing si-p53, GFP, and mutant HRAS. Tumors arising from the various CRE tissue specific promoters and differing injections sites were compared to normal hippocampus and cortex.

View SamplesEGFRvIII is the most common deletion mutant of EGFR in human cancer and its levels are highly correlated with poor prognosis in GBM. The deletion of exons 2-7 removes most of the extracellular ligand binding domain, so it is unable to bind EGF or other EGFR-binding ligands. Nevertheless, the mutant receptor is constitutively phosphorylated, and is capable of activating downstream signaling pathways at a low level.

View SamplesThe establishment of induced pluripotent stem (iPS) cells methodologies has widened the possibilities of stem cell related clinical therapies. However, safety concerns over current reprogramming technologies as well as lack of efficient protocols for differentiation raise serious questions over their usage in clinical settings. Direct lineage conversion may represent a safer technology for cell-therapy. Here, we identify Sox2 as a factor able to transdetermine human mesenchymal stem cells (MSCs) to hematopoietic progenitor cells (HPCs), recapitulating the molecular events during in vivo hematopoiesis. This technology offers an efficiency of up to 70% HPC generation in less than 8 days under feeder-free conditions. With the goal of devising ways for transplantation into diseased patients we developed two different methodologies that avoid exogenous DNA integration or viral infections. The first, by transduction of recombinant Sox2 protein, and the second by functional replacement of Sox2 by inhibition of TGF signaling. The DNA integration-, virus-, and feeder-free transdetermination system here described may complement and enhance current approaches for autologous as well as heterologous HPC transplantation in humans.
