Here, we present several simple methods for evaluating viability and death in 3D cancer cell spheroids, which mimic the physico-chemical gradients of in vivo tumors much better than the 2D culture. The spheroid model, therefore, allows evaluation of the cancer drug efficacy with improved translation to in vivo conditions.

Therapeutic compounds are often first examined in vitro with viability assays. Blind cell counts by a human observer can be highly sensitive to small changes in cell number but do not assess function. Computerized viability assays, as described here, can assess both structure and function in an objective manner.

Central to the field of bacterial pathogenesis is the ability to define if and how microbes survive after exposure to eukaryotic cells. This article outlines protocols for the use of fluorescent dyes that reveal the viability of individual bacteria inside and associated with host cells.
FAQs
Cancer Cell Viability assays use distinct readouts to examine how experimental conditions affect tumor cells. Metabolic assays indicate cellular activity, membrane-integrity measurements indicate whether cell boundaries remain intact, ATP assays measure cellular energy levels, and proliferation assays track cell multiplication. Selecting among colorimetric, luminescent, or fluorescent formats helps align the measurement with the biological response under investigation.
These readouts examine different properties of cultured cancer cells rather than one identical endpoint. A treatment may alter metabolism, cellular energy, membrane condition, or proliferation to different extents. Consequently, results should be interpreted according to the measurement used and the defined experimental conditions, especially when comparing treatment responses across assays or experimental groups.
Parallel viability measurements in malignant and normal cells help researchers examine whether an experimental condition affects tumor cells differently from nonmalignant cells. This comparison adds selectivity context to treatment-response data. It can therefore support evaluation of chemotherapy, targeted agents, radiation, or other interventions intended to produce stronger effects in cancer cells than in normal cells.
A basic workflow begins by culturing cancer cells under defined conditions, exposing them to the experimental treatment or stress, and then measuring a selected viability-related property. Researchers may assess metabolic activity, membrane integrity, ATP levels, or proliferation using colorimetric, luminescent, or fluorescent assays. The resulting measurements provide the basis for comparing experimental conditions.
Researchers use these measurements in drug screening, dose optimization, resistance studies, and comparisons between malignant and normal cells. The approach also supports experiments involving chemotherapy, targeted agents, radiation, gene perturbations, or environmental stresses. In each setting, the assay provides a quantitative basis for examining how a defined intervention changes cancer-cell survival or function.
In resistance studies, viability measurements allow researchers to compare how cancer cells respond to an experimental treatment under defined conditions. Repeated comparisons across interventions or treatment levels can identify differences in response and support dose optimization. When combined with chemotherapy, targeted-agent, radiation, or gene-perturbation experiments, these data help characterize treatment effects relevant to cancer therapy development.
