Figure 1From: Selective regulation of nerve growth factor expression in developing cutaneous tissue by early sensory innervationLevels of NGF, BDNF and NT3 mRNA relative to GAPDH mRNA in maxillary processes dissected from E10.5 and E11 embryos and either not cultured (Mx 0 hours) or cultured for 48 hours alone (Mx 48 hours) or with the trigeminal ganglion attached (Mx + TG 48 hours). Statistically significant differences in neurotrophin mRNA levels between maxillary processes cultured for 48 hours alone and maxillary processes cultured with attached trigeminal ganglia were only observed in the case of NGF mRNA: *P < 0.05 (n = 24); **P < 0.001 (n = 23). Means ± standard errors of the mean are shown.Back to article page
