Fetal development of the human epiglottis revisited: appearance of GFAP-positive mesenchymal cells and fibrous connections with other laryngeal and lingual structures.


The fetal anatomy of the human epiglottis has not yet been fully described. We investigated the histology (paraffin-embedding) of 18 mid-term fetuses at 7-25 weeks of gestation (three fetuses each at 7, 9, 12, 15, 20 and 25 weeks).
