Scanning electron microscopical studies of developing of vallate papillae in the rabbit (Oryctolagus cuniculus f. domestica)
Summary.

This study was conducted on 30 tongues of the rabbits (Oryctolagus cuniculus f. domestica) of both sexes, which were collected at day 18, 20, 22 and 26 of prenatal development (E) and at day 1, 15 and 30 of postnatal life (P). Developmental changes of the rabbit vallate papillae were studied using scanning electron microscopy (SEM). The study showed that the first primordia of vallate papillae were observed at E18. At E20, SEM revealed that primordia of this papillae could be recognized as a circular structures. The furrow of vallate papillae started to form from E22 and finished at P30. After removal the epithelium of the developing vallate papilla, round connective tissue core was exposed. From P1, connective tissue cores of these papillae were formed by varied in length and shape folds. There were irregular hollows between folds. Around connective tissue core there was a circular depression and elevation. Starting from E26 on the surface of developing papillae exfoliating epithelium cells were observed.

Key words: connective tissue core, morphogenesis, scanning electron microscope, vallate papillae
