Tissue sources represented in UniGene data. Based on tissue source information for the 639 mouse EST libraries, libraries were grouped into different organ systems (A). Embryo, whole embryo or part of embryo regardless of stage; part of body, combinations of adult organs or body parts; culture, cell culture, including stem cell libraries. Based on this grouping, the relative contribution from each tissue to the 2.7 million ESTs in the data was calculated (B).
