Figure 4: Percentage of cells exhibiting calcium increase and calcium oscillations during the FCW under different experimental conditions: (a) Percentage of cells displaying increased cytosolic calcium with respect to the total number of cells in the microscopic field. (b) Percentage of cells displaying calcium oscillations with respect to the total number of cells showing calcium increase. Data correspond to the cells between the 1st and the 15th rows. The asterisk () indicates significant difference with respect to control (p < 0.05).
