Figure 6

Competitive binding experiments: (a) Confocal microscopy images of hMSCs pretreated with monoclonal antiCD44 primary antibody and incubated with HA/CS-RhB NPs for 90 min (scale bar = 50 μm); (b) red fluorescent intensities of HA/CS-RhB NPs localized in the cell cytoplasm after 90 min of incubation at 37 °C with (w/antiCD44) or without (37 °C, CTRL) antiCD44 primary antibody. HAs with different Mw were used: 280 kDa (yellow bar), 540 kDa (green bar) and 820 kDa (blue bar). Results are presented as CTCF percentage mean ± SD. **** p value < 0.0001.
