Stem Cell Transfection Solutions

Ideal Entry Points for Transfection in Stem Cell Workflow. Somatic cells such as adult fibroblast cells can be transfected or transduced via several methods (e.g. recombinant virus, plasmid, protein, mRNA, small molecule and miRNA) with a combination of transcription factors including KLF4, SOX2, c-Myc, Nanog, Oct-3/4 and LIN-28 to reprogram the cells to a pluripotent state. iPS cells can then be differentiated to a myriad of cell types through growth factor addition and/or transfection of selection markers driven by cell type specific promoters. Stem cell derived cell types such as cardiomyocytes, adipocytes, neural cells, pancreatic-β cells, and hematopoietic progenitor cells can provide researchers with relevant models for their experiments.

Efficient Genome Editing with Cas9 + Guide RNA Ribonucleoprotein Complexes. TransIT-X2® Dynamic Delivery System was used to deliver Cas9 protein/guide RNA ribonucleoprotein (RNP) complexes in human induced pluripotent stem cells (iPSCs). A T7E1 mismatch assay was used to measure cleavage efficiency at 48 hours post-transfection.
