Which type of gene is most likely to be widely expressed in the body of someone who has a superficial scrape?

A superficial scrape affects the skin, so the body needs to make new skin cells to repair the damaged area. The gene that controls the production of skin cells is therefore the most relevant and likely to be expressed. Genes for red blood cells or cardiac cells have roles in other tissues, while stem-cell production is not the specific repair need described.
