Reply: Exosomes are Comparable to Source Adipose Stem Cells in Fat Graft Retention with Up-Regulating Early Inflammation and Angiogenesis

Sir: We would like to thank Drs. Filippo Boriani and Francesca Perut for their thoughtful letter on the subject of exosome and its potential biomedical applications.1 In our study, unlike a similar article2 cited in the letter, which reported proinflammatory and angiogenic effects of extracellular vesicles isolated from adipose-derived stem cells, we specifically compared the functions of adipose-derived stem cell–derived exosomes (a...
