title: Morphometric analysis of fetal rat hepatocytes cultured in monolayer or following gyratory shaking.
abstract: The stereological technique was used to quantify glycogen areas and endoplasmic reticulum in fetal rat hepatocytes cultured for 24 hr in monolayer (monolayer cells) or following shaking by gyratory rotation (shaken cells). The volume density and volume per cell of glycogen areas decreased in order of freshly isolated hepatocytes, monolayer cells, and shaken cells. The surface density and area per cell of smooth endoplasmic reticulum increased in order of freshly isolated cells, monolayer cells, and shaken cells. The results show that the decrease of glycogen areas and proliferation of the smooth endoplasmic reticulum are more prominent in shaken cells than in monolayer cells. Prominent proliferation of the smooth endoplasmic reticulum in shaken cells may be due to the consumption of glycogen for energy release as a result of gyratory rotation.
