Figure 4.
A set of typical [Ca2+]i transients of individual cells in the (a) linear and (b) hexagonal chain patterns. Roman number represents the position of a cell in the network as defined in figure 1. The calcium responses were recorded for approximately 5 min, 1 min for baseline and 4 min during AFM indentation. The [Ca2+]i concentration is represented by the cell image intensity normalized to the average value of baseline images. Solid lines, cell I; large dashed lines, cell II; small dashed lines, cell II′; dotted lines, cell III; dashed double dotted lines, cell III′; dashed dotted lines, cell IV.
