Sensory receptor-like cells in the human foetal vomeronasal organ
Abstract
The vomeronasal organ (VNO) was studied in ten human foetuses, 12 to 36 weeks old. At 12 to 23 weeks, it was lined by a smooth pseudostratified epithelium, with neurone-specific enolase (NSE) positive cells looking like olfactory receptors. Clusters of NSE-positive cells were seen in relation with the posterosuperior end of the organ and along nerve fascicles in the nasal septum. At 36 weeks, the organ was lined by a respiratory epithelium and did not show any receptor-like cells; some pear-shaped NSE-positive cells of unknown significance were seen at the upper part of the respiratory epithelium. Our results suggest that during the early foetal period, the VNO could have some, as yet unknown, sensory function.

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.
