Dermal fibroblast fibroblast and a corneal fibroblasts are placed in the same concentrations of fibroblast growth factor, dermal fibroblast will not differentiate or change. As noted by Dr. J. Lewis and Dr. A. Johnson authors of "Microbiology of the Cell", "fibroblasts from the skin are different" and behave differently from other fibroblast cells to identical chemical stimuli. Furthermore, dermal fibroblasts are less likely to replicate in either "in vivo" and "in vitro" environments than are other fibroblast types. Dermal fibroblasts require far higher concentrations of fibroblast growth factor (FGF) in order to undergo cell replication. Dermal fibroblasts are responsible for creating the
Female body shape have been exactly identical to the Vitruvian Man because the human body is always changing to adapt its environment. "In the more than five centuries since, human height has changed." In fact, when Da Vinci was drawing this figure in the 15th century, the average height of men of European ancestry was 5'6"–5'8"; however the average male height today is 5'9"–5'11". Kilgore ends his experiment stating that the Vitruvian Man does not accurately describe the modern male or female. In another social experiment, researchers Kara Crossley, Piers L. Cornelissen, and Martin Tovée explore what an attractive body is, asking multiple
