Vascular Endothelial Growth Factor Release Following Electrical Stimulation in Human Subjects

Significance: Angiogenesis is an important phenomenon involved in the healing of chronic wounds, and it is mainly mediated by the release of vascular endothelial growth factor (VEGF) from endothelial cells. Electrical stimulation (ES) is a well-documented treatment used to assist the healing of chronic wounds. Due to the importance of VEGF in the healing process, and the need to know the mechanisms of action of ES involved in the process, this report aimed to determine by a literature review whether the VEGF release occurs following ES in human subjects. Recent Advances: The findings of this literature review suggest that ES releases VEGF, and this effect may be responsible for promoting angiogenesis after ES. Critical Issues: Despite the findings of this literature review on the release of VEGF by ES on wound healing are promising, a large number of studies are needed to confirm such effects. Future Directions: Further studies should be conducted to identify the best parameters and treatment schedule of ES to be used for the VEGF release.
