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

Abstract

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).
