Description
Abstract
We investigated hamster parathyroid glands
of different ages using electron microscopy and found a
new cell type in young, adult and senile hamsters.
Theses special cells were located in interstitial tissues
and invariably contained severa1 lipid droplets within the
cytoplasm. The cells showed an elongated spindle with
some cell processes. The cells contained small Golgi
complexes and moderate cisternae of the granular
endoplasmic reticulum. The morphological
characteristics of these cells were mostly the same as
those of lipid-storing cells in other organs (Yamada and
Hirosawa, 1976). After vitamin A administration, the
lipid droplets in these cells markedly increased in
number and also in volume density. The other
morphological features of these cells resembled those of
the control animals. We called these cells parathyroid
lipid-storing cells. They may incorporate and store
vitamin A within the lipid droplets. They can be
classified as one of the cellular components in hamster
parathyroid gland.
