Objective To explore the effect of macrophage colony stimulating factor (M-CSF) on lung cancer cell line A549. Methods After M-CSF at 0.1
1 and 10 ng/ml was given to cultured A549 cells for 0
24
48
72 and 92 h respectively
their morphological changes were observed with inverted microscopy
proliferation was measured by MTT assay
and cell cycles were determined by flow cytometry. RT-PCR was used to detect the change of expression of M-CSF receptor. Result The growth of A549 was significantly inhibited by M-CSF in a concentration- and time- dependent manner. The maximum response was obtained at 10 ng/ml of M-CSF. Flow cytometric analysis revealed that the t
reated A549 cells arrested at the G

phase of the cell cycle. RT-PCR showed that the mRNA expression of M-CSF receptor was reduced after the M-CSF treatment. Conclusion M-CSF has an anti-tumour activity on lung cancer cell A549.
