Figure 3: SDF-1α loaded into liposomes does not alter particle diameter or surface charge.

Figure 3:

(A) Quantification of liposomal polydispersity index (PdI), encapsulation efficiency (EE%), and diffusion coefficients in water as measured by dynamic light scattering. (B) Cryo-TEM imaging of lipoSDF shows mostly spherical, unilamellar particles averaging around 200 nm in diameter (Scale bar: 200 nm). (C, D) Size and (E, F) zeta potential distributions of loaded and unloaded liposomes. The means between the two groups do not differ significantly (n = 3, mean ± STD. Student’s T-test, p > 0.05). Each measurement was conducted with a different preparation of liposomes.
