The epidermal cells of sponges are responsible for cell adhesion and maintenance of their shape and structure. The epidermis is composed of pinacocytes (epidermal cells) which are flattened cells in the sponge's body wall.
Epidermal cells receive nutrients and oxygen from the blood vessels in the dermis.
An epidermal cell is a cell that is part of the outer layer of an organism. For example, in humans, skin cells are epidermal. Leaves on plants have epidermal layers on the top and bottom of the leaf.
Leaf epidermal cells are examined by making peelings of epidermal cells from both sides. Normally these peelings are stained and examined under the compound microscope.
The epidermal cells have their edges folded over which is part of the structure. This is as a result of the growth factors which makes the cells to proliferate.
The cells on the epidermis have definite life cycle. Each epidermal cell begins life deep in the epidermis, where cells divide to form new cells. The new cells gradually mature and move upwards in the epidermis as new cells form beneath them. After about two weeks, the cells die and become part of the surface layer of the epidermis. Hope this helps!!

HIV mainly attacks cells in the immune system. I'm not aware of a major impact on skin (epidermal) cells.
