| 内容記述 | We compared the circadian oscillation of melatonin release from cultured pineal cells in Japanese quail, pigeon and house sparrow, to determine whether the pineal gland of these species retains the circadian oscillator function in vitro. After dissociated pineal cells have been cultured for 4 days under 12 h: 12 h light-dark （LD） cycle, they were perfused at a flow rate of 0.25 ml/h for 6-7 days under LD or constant darkness （DD）. Melatonin release increased during the dark period and low during the light period in all pineal cell cultures. Under DD conditions, the circadian rhythm of melatonin release persisted for up to 3-4 cycles in pigeon and house sparrow pineal cells, but the amplitude of the rhythm decreased gradually. However, in Japanese quail pineal cell culture the circadian oscillation of melatonin release was weak or abolished under DD conditions. These results strengthen the argument that the avian pineal gland's role in circadian organization differs between species. The direct demonstration of species-specific differences in the mechanism of the circadian oscillation of melatonin release from pineal cells should provide a useful model for the analysis of the pineal's circadian system at the cellular level. | |||||
