Figure 3. Cell morphology observation by light microscopy.

MDPC-23 cells were seeded to 12 well plate (non-treated tissue culture polystyrene) at the concentration of 1×10⁴/mL in DMEM supplemented with 5% FBS. The photograph was taken 20 hours after inoculation. Cells adopted well spread and spindle shape in Fn(10-50) and PCOL-300, while those in control and Fn(0.1-1) were in round shapes.
