Effect of natural-based biological hydrogels combined with growth factors on skin wound healing

Skin wound healing is a continuous and complex process affected by many factors. Growth factors play an important role in the process of wound healing. Local application of growth factors can significantly promote wound healing. However, the degradation and time dependence of growth factors require appropriate delivery systems to help them play a role in wound healing. In recent years, wound dressing products with hydrogels as matrix materials or main components have shown obvious advantages in promoting wound healing. By modifying the hydrogel or combining it with other factors or materials that are beneficial to wound healing, the healing effect can be further enhanced. This review will introduce the research status of growth factors and hydrogels based on natural biological materials in skin wound repair and review the effects and research progress of the combination of growth factors and hydrogels in skin wound healing.
