Specific spots in selected expression profiles: Tongue (panel a), oral mucosa (b), skeletal muscle (c), pituitary gland (d), cerebral cortex (e) and hypothalamus (f). The SOM-pattern of tongue (a) shows two spots of upregulated metagenes. One of them is characteristic for mucosa type tissues (b; red circles) and the other one is found in muscle tissues (c, yellow circles). Pituatary gland (d) shows a specific spot for this particular tissue and one which is characteristic for nervous system tissues (e and f, blue circles) as well.
