Fig. 6. Adamts20 is expressed in the dermis. Radioactive in situ hybridization of Adamts20 expression during mouse skin development at E13.5 (A), E14.5 (B), E15.5 (C,D), E17.5 (E,F) and E18.5 (G,H). In A and B, the arrows indicate the epidermis where no hybridization is seen and D indicates labeling of cells in the dermis. In C,E,G, labeling of dermis is seen, as well as intense hybridization of cells in epidermal appendages. The arrows in corresponding DAPI-stained images illustrate hair follicles in D,F. (G,H) Images from the snout region showing intense staining in vibrissae follicle. Images A-C,E,G use red pseudocolor to identify silver grains viewed under dark-field illumination and blue staining corresponds to DAPI-stained nuclei viewed under UV light. Images D,F,H show DAPI staining alone of the same images shown in C,E,G, respectively. Scale bar: 50 µm.
