epidermal growth factor (egf), a growth factor involved in cell growth and differentiation, is a small polypeptide with molecular weight of approximately 6 kda known to be present in a number of different mammalian species. experimental studies in animals and humans have demonstrated that the topical application of egf accelerates the rate of epidermal regeneration of partial-thickness wounds a...

Abstract Instead of waiting to fight diseases inside the human body, engineering can establish lines defense further out by either intercepting and neutralizing pathogens before they reach humans or diluting them so much that can’t build up an infective load. Good create robust public health.
