Fig. 8.
Distribution of embryonic day (E)15 trigeminal ganglion (TG) neurons based on their soma size in the presence of nerve growth factor (NGF), neurotrophin-3 (NT-3), or mixture of both neurotrophins. Note that the vast majority of neurons are small cells in NGF-treated cultures. In NT-3-treated cultures, there is a wider range of soma size with a distinct tendency towards larger neurons. In the presence of both neurotrophins, soma size of neurons also show a wide distribution with peaks in the small and large cell body ranges.
