Zigzag skin incisions heal five times faster than straight ones.

Scientists used in the experiments epithelial cells from the kidneys of dogs, which are similar in structure to human skin cells. They make up the structural tissue that covers our body. Next, biologists made incisions of various shapes and widths and looked at how this affects the healing process. It turned out that with curved cuts, it is easier for cells to connect with each other. Physicians and surgeons can use this knowledge to develop better strategies for operating and caring for patients' wounds in the future.
