Figure 3. In the tongue epithelium, expression of both Bdnf and Ntf4/5 decreases during embryonic development.
The expression ratio for Ntf4/5 was about 4-fold higher than for Bdnf at E12.5 (A), while TrkB expression was almost undetectable. As development progressed (E12.5 to P0) expression levels for both Bdnf (B) and Ntf4/5 (C) decreased from E12.5 to birth. Error bars show standard error.
