Fig. 3. Histograms illustrating the quantitative analysis of process formation for each MAP2 construct. For cells expressing either a truncated or full-length MAP2c and MAP2b that had processes, the percentage of cells having one, two, or more than two processes per cell was analyzed. Three sets of experiments were analyzed and 150 cells were measured for each protein in each set of experiment. The distribution of cells having one, two, or more than two processes was analyzed by chi-square tests. Chi-square tests were performed to compare the pattern of process formation of the different MAP2 constructs. For all measurements, comparisons between the constructs were significant with a P<0.0033. The brackets indicate the constructs that are not statistically different.
