An assay to quantitatively measure Transforming Growth Factor (TGF)-β-induced invasion in 3-dimensional collagen gels is described. This assay takes advantage of the MCF10A series of cell lines, which represent different stages of breast cancer development. This method can be adopted to be used with other cell lines and might be used to investigate other potential activators or inhibitors of invasion.

2023
The microplate reader is a multimodal instrument that allows for a variety of experiments to be performed and measured simultaneously. Microplate readers can make absorbance, fluorescence and luminescence measurements. Multiwell plates are integral to the microplate reader and allow for many experiments to be performed at once. Regardless of the assay type, experiments on the plate reader utilize a standard curve to determine the experimental values. This curve uses samples of known...

FAQs
Low-attachment wells limit cell adhesion to the plastic surface, allowing cells to settle together and establish cell-cell contacts. These contacts drive the formation of compact aggregates rather than a flat layer. The resulting organization makes it possible to examine how cells assemble into tissue-like structures and how that arrangement changes under different experimental conditions.
Spheroid size, shape, viability, and cellular behavior provide complementary indicators of response. Changes in size can reflect altered growth, while shape may indicate disrupted organization or morphogenesis. Viability shows whether cells remain alive, and behavioral changes can reveal effects on cell-cell signaling or other developmental processes. Monitoring these features over time strengthens interpretation.
Three-dimensional organization creates cell-cell relationships and spatial arrangements that are less prominent in many two-dimensional cultures. Because developmental processes depend on tissue organization, morphogenesis, differentiation, and signaling between neighboring cells, spheroids can provide a more relevant context for studying these events. The comparison is especially useful when a flat culture does not reflect tissue-like behavior.
Cells are placed into nonadherent or low-attachment microplate wells, where they settle and associate with one another. The developing aggregates are then maintained under the chosen experimental conditions and monitored over time. Quantitative imaging can track changes in size and shape, while additional observations assess viability and cellular behavior across the parallel wells.
Evaluation can combine quantitative imaging with measurements of spheroid size and shape, alongside assessments of viability and cellular behavior. Repeated monitoring over time shows whether aggregates grow, retain their organization, or respond to an intervention. Using several readouts helps distinguish a change in overall growth from changes in survival, morphology, or developmental behavior.
The format is useful when researchers need to examine tissue organization, morphogenesis, differentiation, or cell-cell signaling in a three-dimensional setting. It can support studies of how growth factors, drugs, or genetic perturbations influence these processes. Spheroids therefore provide an experimental bridge between simple cell culture and questions about coordinated developmental behavior.
Standardized microplates support parallel experiments under multiple conditions, making comparisons more systematic. Their well-based format also facilitates quantitative imaging and repeated monitoring of spheroid properties. This organization is valuable when testing growth factors, drugs, or genetic perturbations because researchers can evaluate several treatments or conditions while tracking changes in growth, structure, viability, and behavior.
