Figure 2. Effects of barium on anchorage-independent growth and invasion of HaCaT cells.

Figure 2

A, Anchorage-independent growth of HaCaT cells treated with 0–100 µM of barium was evaluated by the colony formation assay. Level of anchorage-independent growth is presented as number of colonies in a graph (left) and photographs (right). B, Number of invading HaCaT cells treated with 0 or 5 µM of barium in the invasion assay is presented in a graph (left) and photographs (right). * and **, Significantly different (*, p<0.05; **, p<0.01) from the control by the Kruskal-Wallis test (A) and Mann-Whitney U test (B).
