Abstract
A serum exosome with high osteogenesis and high angiogenesis, a preparation method and an application thereof are provided, which belongs to the field of bone defect repair technologies. The serum exosome is derived from a serum in a fracture recovery period, and the fracture recovery period is in a range of a second week to a fifth week after fracture. It has been found that the exosomes extracted from the serum after fracture have stronger osteogenic and angiogenic properties than exosomes extracted from normal serum, which is helpful to solve problems that large segmental bone defects, extensive traumas and other diseases are difficult to repair, and provide a new therapy for all diseases that need to be repaired and cured through osteogenic and/or angiogenic properties.
