Overview of gene expression changes after addition of BMP-7 to sympathetic neurons.

Venn diagram showing concordance of significant changes in transcript levels between treatment comparisons. The numbers in each section refer to the number of annotated genes that were found to be significantly different between treatment groups (p<0.05, 1.2 fold change up or down). Specific genes corresponding to groups identified by the letters A through G are identified in Tables S3, S4, S5 available in on-line supporting information.
