Age-related health decline has been attributed to the accumulation of senescent cells recognized in vivo by p16(Ink4a) expression. The pharmacological elimination of p16(Ink4a)-positive cells from the tissues of mice was shown to extend a healthy lifespan. Here, we describe a population of mesenchymal cells isolated from mice that are highly p16(INK4a)-positive are proficient in proliferation but lack other properties of cellular senescence. These data, along with earlier reports on p16(Ink4a)-positive macrophages, indicate that p16(Ink4a)-positive and senescent cell populations only partially intersect, therefore, extending the list of potential cellular targets for anti- aging therapies.
与年龄相关的健康衰退被归因于通过p16(Ink4a)表达在体内识别出的衰老细胞的积累。从小鼠组织中通过药理学方法清除p16(Ink4a)阳性细胞可延长健康寿命。在此,我们描述了从老鼠体内分离出的一群间充质细胞,这些细胞高度p16(INK4a)阳性,具有旺盛的增殖能力,但缺乏细胞衰老的其他特征。这些数据,连同早期关于p16(Ink4a)阳性巨噬细胞的报道,表明p16(Ink4a)阳性细胞群和衰老细胞群只是部分重叠,因此,扩展了抗衰老疗法潜在细胞靶点的清单。
