Figure 8From: Drug-induced cell cycle modulation leading to cell-cycle arrest, nuclear mis-segregation, or endoreplicationExposure to 3 μM Cdk4 inhibitor caused NMuMG/Fucci2 cells to undergo G 1 arrest or endoreplication in a cell-cycle phase dependent manner. When the drug was applied, the observed cells were in early G1 (A), late G1 (B), G1/S (C), and S/G2 (D) phases. Scale bar, 10 μm. (B) A white arrow indicates the endoreplication. (C and D) M, M phase. A solid arrow indicates a daughter cell, which was tracked. A solid arrowhead indicates the other daughter cell.Back to article page
