Transplantation of neural stem cells (NSC) appears to be a promising regenerative therapies for various neurological disorders. However, NSC engraftment limited by the number of surviving cells. To maximize the effect of stem cell-mediated, time of implantation and the number of cells should be appropriately evaluated. Here, transgenic murine NSC line is optimized for high-level expression of the imaging reporter Luc2 and copGFP. NSC 150 000, 75 000, 15 000 or 1500 cell or Hanks buffered saline solution infused into the striatum of nude mice. NSCs survival was monitored by in vivo bioluminescence imaging (BLI) over 2 weeks and part of the brain that are histologically analyzed for the glial cells of the innate immune system.
Longitudinal Data vivo survival BLI revealed significantly reduced with the highest level of 150 000 engrafted NSCs. Cell loss is not correlated with the number of Iba-1 + immune cells or GFAP + astrocytes. histological quantification copGFP + cells at 14 days pasaimplantasi the data confirmed in vivo with the highest density copGFP + cells in 150-cell graft 000 and the highest survival rate for 1500 cells / graft. In conclusion, regenerative therapies should be rigorously evaluate the maximum number of stem cells to be transplanted in a single location, such as the results show that there is a critical limit cell is able to survive in the adult brain. Survival is limited by the availability of oxygen and nutrients, but not the inflammatory response caused by the implantation.
Gene therapy is a rapidly evolving field of molecular medicine. New, effective, and promoter-specific cancers in high demand by researchers seeking to treat cancer therapy via gene expression. Here, we are creating a combinatorial library of chimeric tumor-specific promoter module to identify new promoter with the desired function.
The library was constructed by combining the random fragments of the promoter of the eight human genes involved in the control of cell proliferation. Swimming promoter chimeric incorporated into lentiviral expression vector upstream CopGFP reporter genes, transduced into A431 cells, and enriched to an active promoter with cell sorting. Enriched library containing a very high proportion of active and tumor-specific promoter. This approach for generating combinatorial libraries of chimeric promoters may serve as a useful tool for selecting the promoter very specific and effective for cancer research and gene therapy.
Initial graft size and not the innate immune response limit survival of engrafted neural stem cells.
Transcriptome interstitial cells of Cajal express the unique gene signatures and selective.
Data scale transcriptome can reveal important clues in understanding the underlying molecular mechanism behind a particular cellular function and biological processes. Transcriptomics is a constantly evolving field of research use in biomarker discovery. Transcriptomic profile interstitial cells of Cajal (ICC), which serves as the slow-wave electrical pacemaker for gastrointestinal (GI) smooth muscle, has not been revealed.
ICC copGFP-label use of rats and flow cytometry, we isolated a population of ICC of murine small intestine and colon and obtain their transcriptome. In analyzing the transcriptome, we identified a set of unique markers including the ICC-restricted transcription factors, epigenetic enzyme / regulator, growth factors, receptors, protein kinase / phosphatase, and ion channels / transporters. This analysis provides new and unique insights into the cellular and biological functions of the ICC in GI physiology. In addition, we construct a genome browser interactive ICC

(http://med.unr.edu/physio/transcriptome) based UCSC genome database. To our knowledge, this is an online resource that provides a complete library of all known genetic transcripts expressed in primary ICC. Our genome browser offers a new perspective of an alternative expression of genes in the ICC and provide valuable reference for future functional studies.
