Figure 3From: SHP1-mediated cell cycle redistribution inhibits radiosensitivity of non-small cell lung cancerAssessment of cell cycle in A549, A549S1 and A549S2 cells. Following culture for three months, cell cycle progression of A549, A549S1 and A549S2 cells were detected by FACS analysis (**P < 0.01 vs. A549 cells).Back to article page
