Apoptosis: a basic physiologic process in wound healing
Abstract
Apoptosis, or programmed cell death, is a complex network of biochemical pathways for controlling such events in a cell. Apoptosis is essential, as its failure can lead to disease. Because apoptosis concerns the regulation of sequential events, including the removal of inflammatory cells and the evolution of granulation tissue into scar tissue, it has an essential role in wound repair. This article examines the literature and proposes that apoptosis features in the development of diabetic foot wounds. Hyperglycemia deregulates the sequential apoptotic events by multiple mechanisms, leading to delayed wound healing. Deregulated apoptosis is emerging as a prominent cause of delayed wound healing, especially in diabetic wounds, along with the well-known triad of peripheral vascular disease, neuropathy, and infection.
