The first 18 tags of the list of tags with significant differential frequency of occurrence between libraries are shown (ordered by increasing p-value). Three additional ventral tags are also included (DV22, DV25 and DV38). *Normalized ratio is the ratio of relative dorsal and ventral frequencies, considering 31,175 total dorsal tags and 32,047 total ventral tags. Negative numbers indicate a higher ventral frequency. ^† p-value given by the eSAGE software for the differential expression of each tag between both SAGE libraries.
