FIGURE 2:
Different modes of neurite outgrowth in NGF- and dbcAMP-treated PC12D cells. PC12D cells were treated with NGF or dbcAMP and imaged every 5 min for 5 h. The length of the longest neurites was measured for each image. The number of experiments was as follows: NGF (n = 12), dbcAMP (n = 12). (A) Two representative time-dependent changes in neurite length are shown for NGF-treated cells (left) and dbcAMP-treated cells (right). (B) The bar graph shows the average of accumulated deviation from the five-point average, with SE. The symbol indicates the result of a Student's t test (***p < 0.001).
