Gene expression profiles along the planarian A/P axis.

Planarian flatworms have the amazing ability to regenerate their entire body from tiny tissue pieces. This requires self-organising patterning systems to specify the positional identity of cells. In search of these mechanisms, worms of the model species Schmidtea mediterranea were cut into a series of 11 transverse sections and the mRNA content of each section was sequenced (Illumina, 75 bp SE). Collectively, these data provide gene expression profiles along the A/P axis for each gene in the S. mediterranea genome.
