List of extreme probes for each of the tissues grouped according to the three embryonic layers. Ectoderm tissues were olfactory bulb, both hypophyses, pineal gland and hypothalamus; mesoderm comprised fat and muscle tissues; and endoderm, liver, stomach and ileum. An extreme probe for a given group was defined as one where all expression values in the tissue group were either higher or lower than the values in the rest of tissues (Material and Methods). The marginal difference is the difference between the maximum value of the extreme probe in the group of tissues under consideration and the minimum value in the rest of tissues (when marginal difference is negative) or between the minimum value in the group and the maximum value in the rest of tissues (a positive difference). Thus, a negative marginal diference means that the gene is underexpressed; a positive marginal difference, overexpressed. There are two sets of columns for negative and positive marginal differences, respectively.
