Cell uptake of polymersomes at (A) different incubation temperatures and in the presence of various inhibitors of endocytosis for (B) CBSA-PO and (C) PO.

Notes: The bEND.3 cells were incubated with 100 μg/mL PO or CBSA-PO for one hour. Data presented as the mean ± standard deviation (n = 5). **P < 0.01, statistically significant differences by Student’s t-test when compared with the corresponding value of the control.

Abbreviations: PO, polymersomes; CBSA, cationic bovine serum albumin; pheASO, phenylarsine oxide.
