...-drocytes. After day 19, HGF immunoreactivity was also present in the pancreas, submaxillary glands and neural tissues. In addition to immunolocalizing HGF in tissue sections, bioreactive and immunoreactive HGF was extracted and purified from rat fetuses. Other studies demonstrated the presence of HGF and c...

... (27×10 3 M r , connexin 32) and heart (43×10 3 M r , connexin 43). Immunolocalization with antibodies to the rat liver gap junction protein (27 ×10 3 M r) demonstrated a ubiquitous and uniform distribution in all regions of the epithelium and mesenchyme except the nasal placode. In the placodal...

... that the expression of insulin-like growth factors is controlled at the translational level (Haselbacher, 1987). Another problem with immunolocalization is that growth factors are soluble molecules and change with tissue fixation. Referring to work in his laboratory, where they have used gold probes to immunolocalize...
