摘　　要：所有的生物体都存在着调节自身生命活动的生物钟,而使得生命体的各种活动得以有规律的进行。例如,机体内的许多生理活动过程(睡眠-觉醒循环、温度、心率、血压、内分泌、肾脏的活动、肝脏的代谢活动)都受到昼夜节律的调节,即都在昼夜节律起搏器的控制之下。体外培养的机体组织和细胞的生理活动同样具有生物节律特征。本文对体外培养细胞生物钟进行了简要的概述,分析了神经元和外周组织细胞生物钟的分子机制以及存在的问题,为全面阐释生物钟的分子机制提供参考。All organisms regulate their life activities through the biological clock, which makes a variety of activities regular. For example, many physiological activities such as sleep-wake cycle, temperature, heart rate, blood pressure, endocrine and metabolic activity of the kidney and liver are subject to the regulation of circadian rhythms, that is to say they are all under the control of circadian pacemaker. Physiological activity of cell cultured in vitro also possess rhythms. This paper conducts a brief overview of biological clock of cell cultured in vitro and analyzes the molecular mechanism of the biological clock of the neurons and peripheral tissue cell as well as the existing problems, which provide reference for comprehensive inte^retation of the molecular mechanism of biological clock.
