In vitro evaluation of the presence of CCM proteins on the shell of formulated NBs. a Coomassie blue stained proteins of NBs formulated with decreasing percentage of CCM resolved in 4–12% gradient SDS-PAGE (M: protein molecular weight marker; b-e refer to NB names as indicated in Fig. 1e); b FACS histogram showing the presence of CD29, CD61, PD-L1 and CD184 proteins on the surface of NBCCM; c SEM images showing the morphology of NBctrl (top) and NBCCM (bottom). Scale bar = 1 μm.
