In the repair of large bone defects, loss of the periosteum can result in diminished osteoinductive activity, nonunion, and incomplete regeneration of the bone structure, ultimately compromising the efficiency of bone regeneration. Therefore, the research and development of tissue-engineered periosteum which can replace the periosteum function has become the focus of current research. The functionalized electrospinning periosteum is expected to mimic the natural periosteum and enhance bone repair processes more effectively. This review explores the construction strategies for functionalized electrospun periosteum from the following perspectives: ⅰ) bioactive factor modification (bone morphogenetic protein-2 (BMP-2), vascular endothelial growth factor (VEGF) etc.), ⅱ) inorganic compound modification, ⅲ) drug modification, ⅳ) artificial periosteum in response to physical stimuli. Furthermore, the construction of artificial periosteum through electrospinning, in conjunction with other strategies, is also analyzed. Finally, the current challenges and prospects for the development of electrospinning periosteum are also discussed.
