Figure 6. Graphical representation of rate of corneal epithelial cell culture wound closure in siRNA transfected cultures. Wounded siRNA_PMCA4 (blue) transfected hTCEpi cells fail to close the wound defect in monolayer of hTCEpi cell cultures. hTCEpi cells transfected with siRNA_Scrambled (red) do migrate over the wounded area and close the wound defect earlier than hTCEpi cells where PMCA4 expression has been reduced. The asterisk (*) represents a p value equal to 0.01.
