Microscopy Methods Combine to Detect Treatment-Resistant Cancer Cells
BALTIMORE, Oct. 9, 2023 — Therapy-induced senescent (TIS) cells are cancer cells that become resistant to therapies and enter a dormant stage. These cells can emerge from dormancy and induce tumor resistance and relapse. To provide insight into how TIS cells evolve, it is crucial to develop simple, reproducible methods to study the onset and progression of these cells in human cancer cell cultures. An international team from Johns Hopkins University and Italy’s Politecnico di Milano, Fondazione Istituto
