Abstract

Isolated chondrocytes from mouse ribs have been put in culture and maintained for several weeks, till confluence. They retain differentiation, and preliminary data of cells characterization and growth are reported. Electron microscope observations of the cellsin vitro grown are superimposable to those performed on chondrocytes derived from live animals. Mouse chondrocytes, grownin vitro, represent a promising system for the study of bone differentiation, growth and regeneration, also considering the several mutations affecting skeleton formation known in mice, like cn/cn (achondroplasia).

Abstract

Melatonin content and N-acetyltransferase (NAT) activity were studied in the Harderian gland (HG), retina, pineal gland and serum of the frogRana esculenta over a 12L:12D cycle during October-November. A diurnal pattern of melatonin content was found in serum and retina. A circadian rhythm of NAT activity was detected in the retina and in pineal gland, while high levels of the enzyme with no diurnal variations were observed in the HG. These data show for the first time the presence of NAT activity in the HG of an amphibian.
