Isolating gene-corrected stem cells without drug selection.
Progress in isolating stem cells from tissues, or generating them from adult cells by nuclear transfer, encourages attempts to use stem cells from affected individuals for gene correction and autologous therapy. Current viral vectors are efficient at introducing transgenic sequences but result in random integrations. Gene targeting, in contrast, can directly correct an affected gene, or incorpo...
متن کاملIsolating stem cells from soft musculoskeletal tissues.
Adult stem cells have long been discussed in regards to their application in regenerative medicine. Adult stem cells have generated a great deal of excitement for treating injured and diseased tissues due to their impressive capabilities to undergo multi-lineage cell differentiation and their self-renewal ability. Most importantly, these qualities have made them advantageous for use in autologo...
متن کاملGene Delivery to Mesenchymal Stem Cells
There is increasing trend in using recombinant stem cells as novel therapeutic candidates in different diseases. These studies encompass different applications from targeted homing of Mesenchymal Stromal (stem) Cells (MSC), to arming them with different cytokines. Resistance to transfection or transduction methods had urged researchers to look for better gene delivery alternates and optimizing ...
متن کاملKinetics of drug selection systems in mouse embryonic stem cells
BACKGROUND Stable expression of transgenes is an important technique to analyze gene function. Various drug resistance genes, such as neo, pac, hph, zeo, bsd, and hisD, have been equally used as selection markers to isolate a transfectant without considering their dose-dependent characters. RESULTS We quantitatively measured the variation of transgene expression levels in mouse embryonic stem...
متن کاملHomologous integration in mammalian cells without target gene selection.
Homologous integrations into a nonselectable target locus have been highly enriched for following DNA transfections into mammalian cells. The target gene, the SV40 early region in COS1 cells, provides transcription signals to activate a defective selectable marker, the gpt gene. We find that nearly half of the selected clones have integrated the gpt gene at the homologous sequence in the COS1 g...
