Specific Accumulation of Intraperitoneally Injected BSA-NPs in Ectopic Lesions. A, B. TEM image A and hydrodynamic diameters B of BSA-NPs. Scale bar is 200 nm. C, D Ex vivo fluorescence images C and corresponding quantification of average fluorescence intensities of eutopic endometrium, ectopic lesion and major organs D collected 16 h post FITC-BSA-NPs injection by intravenous or intraperitoneal, respectively. N = 5 per group. E Ratio of ectopic/eutopic fluorescence in D. N = 5 per group. F–H. Ex vivo fluorescence images F, corresponding quantification of average fluorescence intensities of the ectopic lesion G and the ratio of ectopic/eutopic fluorescence H at different time points post intraperitoneal injection of FITC-BSA-NPs. N = 5–6 per group. Data were shown as mean ± SEM and analyzed by one-way ANOVA with Turkey’s post hoc test or two-tailed t-test. *P < 0.05, **P < 0.01
