PDGFRA and infection: Furthermore, compared with the H2O2 treatment, fewer Ly6G+ neutrophils and more CD140a+ MSCs could be observed from the Ru-Cu/EDHJ group with S. aureus-infection via immunofluorescence staining, indicating that the high anti-infective efficacy of Ru-Cu/EDHJ can enhance the survival of endogenous MSCs (Supplementary Fig. 53).
