Measuring Drug Response Beyond Cell Viability
2026-09-16
Hannah R. Schwartz’s dissertation distinguishes relative viability from fractional viability to clarify whether an anticancer treatment primarily slows proliferation, induces cell death, or does both. This framework emphasizes matched, time-resolved measurements and provides a practical basis for interpreting drug-response data in cancer research.

How Cancer Drug Response Metrics Shape In Vitro Evidence
2026-09-15
Hannah R. Schwartz’s dissertation distinguishes relative viability from fractional viability, showing that growth inhibition and cell killing are related but non-equivalent components of an in vitro cancer-drug response. Its central implication is practical: assay interpretation improves when researchers measure proliferation and death as separate, time-dependent outcomes rather than treating one viability value as a complete efficacy readout.
