Dermal fibroblast wound site perish. Without fibroblasts, the wound site cannot regenerate extracellular matrix and epidermis skin cells cannot proliferate over the wound site. Therefore, without dermal fibroblasts the skin cannot properly recover from injury. Yet, by differentiating mesenchymal stem cells from other regions of the body and injecting them into the wound site, scientists can restore dermal fibroblasts to burned regions of the body. By restoring fibroblasts to the burned regions, the body can restore the ECM within the wound site and recover from the injury. As noted "The injured dermis is also repaired by the recruitment and proliferation of fibroblasts
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
