mouse {clValid} | R Documentation |
Data from an Affymetrix microarray experiment (moe430a) comparing comparing gene expression of mesenchymal cells from two distinct lineages, neural crest and mesoderm derived. The dataset consists of 147 genes and ESTs which were determined to be significantly differentially expressed between the two cell lineages, with at least a 1.5 fold increase or decrease in expression. There are three samples for each of the neural crest and mesoderm derived cells.
