The dermal cell system, aka the integumentary system, functions to protect the body’s tissues and organs from several injuries; such as dehydration, infectious organisms, and rapid temperature changes. In addition, the dermal system receives sensory information from the environment and produces melanin and vitamin D. Melanocytes, keratinocytes, endothelial cells, and fibroblasts are vital components necessary for normal skin development and function. Abnormal cell proliferation and regulation within the dermal cell system contributes to the development of pathological disorders such as eczema, psoriasis, and melanoma.
