Down-regulation of γ-synuclein in human esophageal squamous cell carcinoma

Figure 4 Colony formation of ESCC 9706 cells transfected with vector and γ-synuclein. 200 cells from each of the cell pools were plated in six-well plates. After 14 days, the colonies were stained with 0.2% p-iodonitroterazolium violet and photographed. The number of colonies per well was quantified. Experiments were repeated three times with consistent and reproducible results.
