Abstract
This review explores the critical role of exosomes in promoting angiogenesis, a key factor in skin flap survival. Skin flaps are widely used in reconstructive surgery, and their survival depends heavily on the formation of new blood vessels. Exosomes, small extracellular vesicles secreted by various cells, have emerged as important mediators of intercellular communication and play a crucial role in biological processes such as angiogenesis. Compared to traditional methods of promoting angiogenesis, exosomes show more selective and targeted therapeutic potential as they naturally carry angiogenic factors and can precisely regulate the angiogenesis process. The review will delve into the molecular mechanisms by which exosomes facilitate angiogenesis, discuss their potential therapeutic applications in enhancing skin flap survival, and explore future research directions, particularly the challenges and prospects of exosomes in clinical translation. By highlighting the unique advantages of exosomes in skin flap survival, this review provides a new perspective in this field and opens up new research directions for future therapeutic strategies.
