Table 1

EST library IDs categorized by the description of developmental stages. Each categorized mouse developmental stage contained about 22,300 (409–71,504) EST counts on average, which corresponded to 2,900 (194–5,923) non-redundant ENSEMBL gene entries on average. Developmental status was based on Manipulating the Mouse Embryo) [27] and The Mouse [28].
