Different Persistence of the Cellular Effects Promoted by Protein Kinase CK2 Inhibitors CX-4945 and TDB

Figure 4

Effects of CX-4945 and TDB on spheroid formation. U2OS cells were pretreated for 24 h with the indicated concentrations of inhibitors and then allowed to form spheroids. Images were taken after 24 h and 96 h. Two separate experiments were performed, with triplicates of each condition (2.5x objective, magnification-changer 1.6). Two representative images for each condition are shown.
