Milk-sEVs promoted bone repair in a mice skull defect model. A Schematic diagram of the mice skull defect model; B external and internal views of the skull defect model; C the result of HE staining (scale bar = 200 μm); the results of Masson staining (scale bar = 200 μm); the results of IHC staining; (n = 4/group) (scale bar = 100 μm). The statistical results are presented as means ± SD, ***P-value < 0.001
