Fig. 8. Neurotrophin levels are not increased in the skin of K14-noggin animals. NGF and BDNF proteins as measured by ELISA of lysates from the whisker pads of 3-day-old mice are unchanged in K14-noggin compared with the wild-type mice and levels of NT3 are actually reduced significantly. Mean±s.e.m. of five animals of each genotype are shown (^*P<0.025).
