Comparative Proteomic Analysis of Human Cholangiocarcinoma Cell Lines: S100A2 as a Potential Candidate Protein Inducer of Invasion

Figure 1

In vitro invasion assays of KKU-M213 and KKU-100 cells were conducted in a transwell unit coated with Matrigel. Cells in serum-free medium were plated in the upper chamber of a transwell unit. After 12 hours of incubation, cells invading to the lower compartment of the transwell unit were stained and counted. The numbers of invading cells are presented as mean ± SE of results obtained from three independent experiments, , compared with KKU-100 cell line.
