The ROS staining results of primary rat GCs after 4-HC and rhLF treatments. a The representative ROS staining results of primary rat GCs in different groups after rhLF treatments. Scale bar = 100 μm. b The relative densities of ROS staining of primary rat GCs in different groups after rhLF treatments. Note: In each panel, labeling with the different letter in each column indicates significant differences between different groups (P < 0.05)
