Representative Photographs of Treated Cells Six Days Post-Treatment. A. Control group: untreated cells. B. IL-6 group: HCC1806 cells were treated with 50 ng/ml IL-6 for 6 days. C. 1,25 D group: HCC1806 cells were treated with 100 nM 1,25D. D. VDR OE. + 1,25D group: HCC1806 were transfected with VDR and treated with 100 nM 1,25D. E. VDR OE. + 1,25D + IL-6 group: HCC1806 were transfected with VDR and treated with 100 nM 1,25D and 50 ng/ml IL-6. The media was replenished every 2 days for 6 days. The effect of treatment on cell morphology was investigated by light microscopy (Magnification x 200)
