Solutions to the problem of the invention are a method for selectively killing or removing a senescent cell, substance identification, and a method for purifying a senescent cell. Specifically, the invention includes an agent for removing a senescent cell, which is a drug for removing an in vivo senescent cell, the agent containing an inhibitor for glutaminase as an active ingredient, and a pharmaceutical composition containing the agent. The invention further includes a method for preparing a senescent cell, including the following steps (a) to (c): (a) synchronizing a cell with the G2 phase; (b) activating an intracellular p53 protein in the cell synchronized with the G2 phase; and (c) inhibiting polo-like kinase 1 (PLK1) activity in the cell treated in the step (b).
