Gene expression profiles of Bapx1 expressing FACS sorted cells from wildtype and Bapx1-EGFP null mouse embryos.

The data described in this article refers to Chatterjee et al. (2015) "In vivo genome-wide analysis of multiple tissues identifies gene regulatory networks, novel functions and downstream regulatory genes for Bapx1 and its co-regulation with Sox9 in the mammalian vertebral column" (GEO GSE35649) [1]. Transcriptional profiling combined with genome wide binding data is a powerful tool to elucidate the molecular mechanism behind vertebrate organogenesis. It also helps to uncover multiple roles of a single gene in different organs. In the above mentioned report we reveal the function of the homeobox gene Bapx1 during the embryogenesis of five distinct organs (vertebral column, spleen, gut, forelimb and hindlimb) at a relevant developmental stage (E12.5), microarray analysis of isolated wildtype and mutant cells in is compared in conjunction with ChIP-Seq analysis. We also analyzed the development of the vertebral column by comparing microarray and ChIP-Seq data for Bapx1 with similarly generated data sets for Sox9 to generate a gene regulatory network controlling various facets of the organogenesis.
