Poly-L-Arginine Induces Apoptosis of NCI-H292 Cells via ERK1/2 Signaling Pathway

Figure 1

Effects of PLA on the morphology of NCI-H292 cells. (a) Control cells were flattened; the cytoplasm stretched to the periphery and adhered to the growth of the support (×8000). (b) In the control group, the mitochondrial ridge displayed continuous integrity and was regularly arranged (×20000). (c) After treatment by PLA, the surface of the nuclear membrane was uneven and the chromosomes were concentrated under it (×8000). (d) After treatment by PLA, the mitochondria were round and empty (×20000).
