Fig. 5From: Small extracellular vesicles from human adipose-derived mesenchymal stromal cells: a potential promoter of fat graft survivalHistological changes in adipose tissue over time. a HE staining revealed that the grafted fat in the hADMSC-sEVs groups exhibited better survival and morphologic integrity (evidenced by the presence of intact and nucleated adipocytes and the presence of cysts and vacuoles) compared to the control group. b, c Semiquantitative scale of integrity and cysts/vacuoles of HE staining (***p < 0.001,****p < 0.0001)Back to article page
