Grb7 expression in the mouse embryo visualised by immunohistochemistry on wild type e14.5 paraffin sections. Representative mid-sagittal sections were chosen to display a wide range of tissues (sections adjacent to those used to stain for Grb14 in Fig. 2). A Whole wild type embryo with expression highlighted in dermis (d), gut (g), inner ear (i), liver (li), lung (lu), nasal epithelium (ne), pancreas (p), pituitary (pi), ribs (r, ossified cartilage), stomach (s), salivary gland (sg) and tooth primordia (tp); B Expression in submandibular gland and tooth primordia; C Expression in kidney (ki) and adrenal gland (ad); D Expression in lung and liver, but not heart (h); E Expression in epithelial lining of mid- and hind-gut; F Endocrine pancreas. Brown staining is indicative of Grb7 expression, magnifications as indicated
