1 Binding of 125I-labelled EGF to skin membrane particles was temperature- and time-dependent, with equilibrium being reached within 1 h at 23 degrees C. Analysis of skin biopsies collected from ten castrated Merino sheep demonstrated the presence of a single class of saturable, high-affinity binding sites with a dissociation constant of 64 +/- 4 (S.E.M.) Iodine-125 epidermal growth factor Mus musculus
2 Autoradiography of skin sections incubated with 125I-labelled EGF in vitro or of sections from skin which was perfused with 125I-labelled EGF in vivo demonstrated that EGF receptors were localized in undifferentiated cells of the epidermis and sebaceous glands, the inner and outer root sheath and bulb of wool follicles and in dermal arterioles. Iodine-125 epidermal growth factor Mus musculus
3 Autoradiography of skin sections incubated with 125I-labelled EGF in vitro or of sections from skin which was perfused with 125I-labelled EGF in vivo demonstrated that EGF receptors were localized in undifferentiated cells of the epidermis and sebaceous glands, the inner and outer root sheath and bulb of wool follicles and in dermal arterioles. Iodine-125 epidermal growth factor Mus musculus
4 Autoradiography of skin sections incubated with 125I-labelled EGF in vitro or of sections from skin which was perfused with 125I-labelled EGF in vivo demonstrated that EGF receptors were localized in undifferentiated cells of the epidermis and sebaceous glands, the inner and outer root sheath and bulb of wool follicles and in dermal arterioles. Iodine-125 epidermal growth factor Mus musculus
5 Differences in receptor concentration were observed between follicles following in-vivo perfusion of 125I-labelled EGF but not when the in-vitro labelling technique was used. Iodine-125 epidermal growth factor Mus musculus
