In vitro cellular uptake and biocompatibility of PPR NPs
(A and B) CLSM images of HK-2 cells, after being incubated with Rho labeled PRP NPs for 1–8 h (left) and their statistic intensities (right). Scar bar, 30 μm.
(C) Cell viabilities of HK-2 cells, after being incubated with PDA, PP, and PPR NPs, using CCK-8 assay.
(D) Cell viabilities of LPS-induced HK-2 cells, after being incubated with PP and PPR NPs, using CCK-8 assay.
(E) LDH leakage of LPS-induced HK-2 cells, after being incubated with PP and PPR NPs, using Elisa assay. n = 3. ∗∗p < 0.01, ∗∗∗p < 0.001. Data are represented as mean ± SEM.
