Abstract

In situ hybridization was used to study the site and timing of the expression of nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin 3 (NT-3), and neurotrophin 5 (NT-5) mRNAs in the developing inner ear of the rat. In the sensory epithelia, the levels of NGF and NT-5 mRNAs were below the detection limit. NT-3 and BDNF mRNAs were expressed in the otic vesicle in overlapping but also in distinct regions. Later in development, NT-3 transcripts were localized to the differentiating sensory and supporting cells of the auditory organ and vestibular maculae. In these sensory epithelia, the intensity of NT-3 mRNA expression decreased in parallel with maturation. The expression of BDNF mRNA was restricted to the sensory cells of both the auditory and vestibular organs, including ampullary cristae. In bioassays, BDNF and NT-3, but not NGF, at physiological concentrations induced neurite outgrowth from the statoacoustic ganglion explants. These results demonstrate that NT-3 and BDNF, rather than NGF and NT-5, are the primary neurotrophins present in the target fields of the cochlear and vestibular neurons. Expression of NT-3 and BDNF mRNAs in the otic vesicle before and during the ingrowth of neurites from the statoacoustic ganglion suggests that NT-3 or BDNF or both may serve as chemoattractants for the early nerve fibers. The results also suggest that these neurotrophins have a role in later development of the cochlear and vestibular neurons.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
