Popis: 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.
