There is tremendous interest in the development of drugs that target senescent cells (‘senolytic’ drugs) to treat a range of age-related morbidities. However, studies in mice that demonstrate impaired tissue repair following clearance of senescent cells raise questions about the potential risks of senolytic therapies. Closer examination of the available studies reveals the hopeful possibility of a ‘therapeutic window’ in which these risks can be minimized.
