Stereological studies of differentiation in hamster cheek pouch epithelium: variations in the volume and frequency of mitochondria.

abstract：:The structure of amniotic papillae in sheep was investigated by light transmission and scanning electron microscopy. Papillae were found on the amnion near the umbilical cord in a majority of the sheep examined, from early mid-term onwards. The papillae possessed a basic connective tissue core with a varying degree of...

These have been considered to be of the peripheral type, i.e. similar to those of hepatic and fat cells rather than of the brain type which show dual specificity for both insulin and insulin-like growth factor (IGF-1). We have examined th...
