Final answer:
A skin graft is produced from fibroblasts and blood vessels that are involved in wound repair.
Step-by-step explanation:
A skin graft is produced from the fibroblasts and blood vessels that are involved in wound repair. When the skin is damaged, fibroblasts mobilize and divide rapidly to repair the tissue by collagen deposition, forming granulation tissue. Blood capillaries follow the fibroblasts and help increase blood circulation and oxygen supply to the area. These cells and blood vessels are collected and used to create a skin graft.
