PTX-CDs inhibited EMT in glioblastoma cells. (A) Cell morphology of aggressive glioblastoma cells was affected by PTX-CDs. (B) Migration and invasion of glioblastoma cells were inhibited by PTX-CDs in Transwell assay. (C) Expression of N-cadherin and Vimentin in glioblastoma cells was decreased, while expression of E-cadherin was increased after PTX-CDs treatment for 24Â h. (D) Immunofluorescent staining of E-cadherin and Vimentin in U251 cells after PTX-CDs treatment for 48Â h
