Atomic force microscopy study of emodin treated MCF 7 human breast cancer cells

... The effects of emodin on the filamentous structures of MCF 7 cells were examined  by acquiring AFM images from three sets of samples: MCF 7 cells, MCF 7 cells pre‐ treated with 20µM emodin,  and MCF 7 cells pre treated with DMSO. About 5 to 10  ... The effects of emodin on the elasticity of MCF 7 cells were examined by collecting  force curves on three sets of samples: MCF 7 cells, MCF 7 ce...
