Subject area	Biology
More specific subject area	Toxicogenomics
Type of data	1)Processed microarray data in .CEL format 2)Excel spreadsheet files listing identified genes, GO terms and functional clusters
How data was acquired	Microarray data generated on Affymetrix Mouse Gene 2.0 ST Array
Data format	Processed or analyzed
Experimental factors	Induction of spontaneous differentiation was achieved through embryoid body (EB) formation in hanging drop culture following a procedure adapted from De Smedt et al.[2]
Experimental features	Cells were collected at 24, 48, and 72 h after exposure to 0.25 mM thalidomide. Total RNA (50 ng) were preprocessed using the Affymetrix GeneChip WT PLUS Reagent Kit and hybridized onto the Affymetrix Mouse Gene 2.0 ST Array
Data source location	Laurel, MD, USA
Data accessibility	The analyzed data is with this article. Processed microarray data (.CEL files) can be accessed at Gene Expression Omnibus with accession number GSE61306 (http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE61306)
