Wound healing is complex and numerous factors overlap perfectly with the goal of wound closure. Among them, we will focus on a large amount of experimental and clinical evidence on the action of GH in wound repair. We will analyze how the physiological rhythm of GH secretion influences this process, and also one of the most important signaling pathways that mediate the effects of GH on tissue regeneration. The role of IGF-1 and the factors that stimulate GH secretion and that have also been shown to improve healing will also be reviewed. In addition, it will be analyzed the cellular senescence process, which plays a key role in nonhealing wounds associated with chronic diseases. The benefit of GH in this last circumstance is especially important. The lesions associated with catabolic states, mainly burns, are considered a delicate situation in which it is extraordinarily difficult to act with growth factors due to the fragile situation of these patients, often children. The positive action of GH in these states will also be described. In summary, we will analyze many evidences about the beneficial effects of GH and its main secretagogues in the healing of wounds.
