Age estimation was one of the important and difficult contents in forensic medicine research and practice. Age estimation was mainly based on bone age and dental age in present. However, the errors were large, and it was influenced by other factors. In recent years, following with the development of molecular biology theories and techniques, researchers have found that some cellular and molecular levels were related to age. In this review, the research progress of molecular biology in age estimation was reviewed.%年龄推断是法医学研究与实践的重点和难点内容之一.目前,年龄推断主要依据骨龄、牙龄等形态学方法,但误差较大、影响因素较多.近年来,随着分子生物学理论与技术的发展,研究者发现某些细胞分子水平与年龄密切相关.本文就目前细胞分子水平与年龄关系的研究进展进行综述.
