title: Pre-elastic (oxytalan) fibres in the developing elastic cartilage of the external ear of the rat.
abstract: During chondrogenesis in the external ear of the rat oxytalan fibres precede the appearance of mature elastic fibres by 6-7 days. The spatial distribution of oxytalan fibres in fetal and neonatal pre-cartilage corresponds to that of the elastic fibres in mature cartilage. These findings support the hypothesis that oxytalan fibres in the pre-cartilage of the external ear of the rat are pre-elastic in nature.
