... is transparent. Both the guanine localized in guanine cells in the opisthosoma and the uric acid localized in epidermis cells in the prosoma are responsible for the white coloration. The bright yellow color is due to the combination of ommochrome pigment granules and the white reflectance from coincident guanine...

... ganglion skin epidermis sense merkel cell Moles are experts at finding prey and navigating dark underground tunnels using the tip of their snout to make sensory discriminations. A close examination of the nasal skin of talpid moles reveals a dense array of small(60 μm) raised bumps. These bumps...

... (with the underlying epidermis removed) from winter larvae provided greater protection from inoculative freezing than did cuticle patches from summer larvae. The results indicate that seasonal modifications in epidermal and hemolymph AFPs contribute most strongly to the inhibition of inoculative freezing. Subcuticular...

..., hydrocortisone (HC) and corticosterone (C), each either supplemented with prolactin (PRL) or lacking PRL. Skin cultured with Aldo alone or with the corticoid mixture (Aldo+HC+C) developed an adult-type epidermis: (i) both types of skin reacted to human blood group antigen A, a marker for the adult-type epidermis...

... to measure. We conclude that neither permeability nor water content data support the existence of a significant water barrier in the region of the epidermis. * Present address: Department of Biology, York University, Downsview, Ontario, Canada M3J 1P3. 23 11 1984 © 1985 by Company...
