Project description:The Human Induced Pluripotent Stem Cells Initiative (HipSci) is generating a large, high-quality reference panel of human IPSC lines. This is a pilot submission of mass-spectrometry analyses from 18 induced pluripotent stem cell lines generated by the HipSci project. This submission includes also data for two embryonic stem cell lines, and one reference sample comprising a mixture of 42 IPSC lines. Raw data files for this study can be accessed from the PRIDE database at EMBL-EBI under accession number PXD003903: http://www.ebi.ac.uk/pride/archive/projects/PXD003903.
