Fig. 1.

Genome-wide gene expression differences between cornea samples, tendon and lens. Heat image of 1087 genes with ≥ 500 arbitrary expression units in at least one sample type shown in green (below mean), black (mean) and red (above mean). Four major functional groups of genes differentially expressed in the different tissue types are shown on the left margin. Symbols of specific genes as they appear across all samples are shown on the right, and underlined if validated by RT-PCR or immunoblotting.
