Fig. 4From: NEP1-40-modified human serum albumin nanoparticles enhance the therapeutic effect of methylprednisolone against spinal cord injuryCellular uptake of NPs by RSC-96 cells and HUVECs. Fluorescently labeled NEP1-40 appeared green; fluorescently labeled NPs, red. Representative images showing a RSC-96 cells or b HUVECs treated with NEP1-40-MP-NPs. Representative images showing c RSC-96 cells or d HUVECs treated with MP-NPs. e Summary of red fluorescence intensity analyzed by NIH Image-Pro Plus 6.0.
