Origin and development of neuroepithelial bodies in fetal rabbit lungs

Summary Light-microscope studies concerning the embryological development of fetal rabbit lungs revealed the occurrence of argyrophilic neuroepithelial bodies in an early gestational stage (i.e. already in the glandular period and from the 18th day onwards). Their morphological characteristics and further differentiation towards birth are detailed.Supported by a grant from the Nationaal Fonds voor Wetenschappelijk Onderzoek — Fonds voor Geneeskundig Wetenschappelijk Onderzoek (Belgium).
