Summary (written by the submitters)

Groundbreaking work demonstrated that ectopic expression of four transcription factors, Oct4, Klf4, Sox2, and c-Myc, could reprogram murine somatic cells to induced pluripotent stem cells (iPSCs) (Takahashi and Yamanaka, 2006), and human iPSCs were subsequently generated using similar genetic manipulation (Takahashi et al., 2007,Yu et al., 2007).

To address the safety issues arose from harboring integrated exogenous sequences in the target cell genome, a number of modified genetic methods have been developed and produced iPSCs with potentially reduced risks (for discussion, see Yamanaka, 2009, and references therein). However, all of the methods developed to date still involve the use of genetic materials and thus the potential for unexpected genetic modifications by the exogenous sequences in the target cells. Here we report generation of protein-induced pluripotent stem cells (piPSCs) from murine embryonic fibroblasts using recombinant cell-penetrating reprogramming proteins. We demonstrated that such piPSCs can long-term self-renew and are pluripotent in vitro and in vivo.

Download · which file do I need?

Direct links to NCBI, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need.

All supplementary files ↗

3 · The original raw files

Whole study · RAW.tar

Everything the authors deposited as one archive (GSE16062_RAW.tar), including the raw array or instrument files. Can be large; the picker in step 2 takes just the samples you need.

Whole study · RAW.tar ↓

What the files usually look like: For arrays the series matrix is normally the normalised expression table you want; the raw array files (CEL and similar) are in the RAW.tar.

Also filed as BioProject PRJNA115481. Searching any of these in the dataset finder brings you back here.
