Project description:Owing to the risk of insertional mutagenesis, viral transduction has been increasingly replaced by nonviral methods to generate induced pluripotent stem (iPS) cells. We report the use of âminicircleâ DNA, a vector type that is free of bacterial DNA and capable of high expression in cells. Here we use a single minicircle vector to generate transgene-free iPSCs from adult human adipose stem cells. (Note: Our Nature Methods publication included analysis of array data from GSM378832 (Foreskin), GSM378833-GSM378838 (JT-iPSC), and GSM378817-GSM378820 (H1, H7, H9, H13, H14) in conjunction with this series). Total RNA from human adipose stem cells (hASC, n = 3 replicate samples), hASC-derived iPS cells using lentiviral factors (lenti-iPSC, n = 3 replicate samples), and minicircle-derived human iPS cells (mc-iPSC, n = 3 subclones from adipose tissue of three individual patients) was hybridized to nine Affymetrix GeneChip Human Genome U133 Plus 2.0 Arrays.
Project description:Owing to the risk of insertional mutagenesis, viral transduction has been increasingly replaced by nonviral methods to generate induced pluripotent stem (iPS) cells. We report the use of ‘minicircle’ DNA, a vector type that is free of bacterial DNA and capable of high expression in cells. Here we use a single minicircle vector to generate transgene-free iPSCs from adult human adipose stem cells. (Note: Our Nature Methods publication included analysis of array data from GSM374067 and GSM374068 in conjunction with this series).

Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
