Data represent fold change in gene expression when HMSCs were cultured in 3D type I collagen hydrogels in the presence of regular and osteogenic exosomes isolated from 4-week cultures. Data are presented as mean fold change in gene expression with respect to control. value specified in brackets shows statistical significance with respect to control obtained by means of Student’s -test.
