Neurite length with and without directional analysis (without Medium Change). (A) Mean and SD of neurite lengths of all four experimental groups independent of the direction of outgrowth. Here, the neurite lengths are significantly longer in the NT-3-treated group than in the NC, CNTF, and NP groups. NC has significantly longer neurites compared to CNTF and to NP. (B) The bar charts illustrate the mean lengths of grown neurites towards (+) or opposed to the osmotic pump (−). Neurites of the NT-3 + group grow significantly longer than neurites of the CNTF + group and neurites of the NC + group. No significant differences are observed within the groups.
