Drug Response Metrics in Cancer In Vitro
2026-10-05
Hannah Schwartz’s 2022 dissertation distinguishes relative viability from fractional viability when evaluating anticancer drug responses in vitro. Its central finding is that growth inhibition and cell death frequently coexist but differ in magnitude and timing, making endpoint selection essential for interpreting drug effects.
