Effect of serum starvation on cell cycle and cell response. A. Flow cytometry of propidium iodide stained cells kept for 16 h in complete medium (left) or in medium with 0.1% serum. The region indicated as 'C' corresponds to G0/G1, 'D' to S and 'E' to G2/M phase of the cell cycle. B. Cell area for cells on thin films of fibrillar collagen (■,□) and thin films prepared from the lower concentration of collagen (●,○). Open circles represent cells that have been serum starved. C. GFP expression on thin films of fibrillar collagen (high) and lower concentration collagen (low). Hatched bars represent cells that have been serum starved.
