Figure 2From: Selective regulation of nerve growth factor expression in developing cutaneous tissue by early sensory innervationLoss of neurons and reduced levels of TrkC and TrkA mRNA in the trigeminal ganglia of erbB3-/- embryos. (A) Number of neurons in the trigeminal ganglia of erbB3+/+ and erbB3-/- embryos at E11 and E12. (B,C) Levels of TrkC mRNA (B) and TrkA mRNA (C) in the trigeminal ganglia of erbB3+/+ and erbB3-/- embryos at E12. Means ± standard error of the mean (SEM) are shown (n = 6 to 8 embryos per data point). (D) Sections of the trigeminal ganglia of erbB3+/+ and erbB3-/- embryos at E11 and E12 labelled with anti-βIII tubulin antibody. Scale bars = 100 μm.Back to article page
