Both head-and-neck cancers and breast cancers, for example, have an abundance of molecules called epidermal growth-factor receptors (EGFRs).
Erbitux, for example, binds to a cell-surface protein called epidermal growth-factor receptor (EGFR).
Lapatinib, it turns out, also inhibits the activity of a protein called the epidermal growth factor receptor, which has been found to be important for stem-cell proliferation.
This will also house the company's infant skin-care business, Bübchen, and will presumably add other epidermal enterprises as time goes on.It will join a family of Nestlé companies that reek more of the laboratory than of the kitchen.
Bird feathers are developmentally modified epidermal scales.
The so-called horns of the horned lizard are specialized epidermal scales; and the rattle of rattlesnakes is a series of dried scales loosely attached to each other, the last one always remaining despite molting of the rest of the stratum corneum.
Whether covered with leaf armour or not, the surface of the fern stem is protected by an epidermis, or "skin," a single layer of epidermal cells, which are more or less flat cells with thick outer walls.
Nevus, plural Nevi, congenital skin lesion, or birthmark, caused by abnormal pigmentation or by proliferation of blood vessels and other dermal or epidermal structures.
Stick insects (Carausius) can change their colour to match that of the background by moving pigment granules in their epidermal cells.
In the case of hairs, the epidermal thickening proliferates downward and forms the root of the hair, from which the shaft then grows outward, emerging on the surface of the skin.
Some of the epidermal protein complexes migrate to the draining lymph nodes, where they stimulate T cells responsive to the newly formed antigen to multiply.
