The uneven loss of medium from microtiter plates affects the reproducibility of uniform multicellular tumor spheroid formation. Improving culture conditions to reduce significant medium loss will improve the reproducibility of spheroid formation and the results of spheroid-based assays using the liquid-overlay technique.

Spheroids are a type of 3D cell culture model used to more accurately represent a cell’s environment compared to 2D cell culture monolayer models. In the example protocol, we will see scientists generate spheroids from a colorectal cancer cell line and apply live-cell imaging to track the spheroids’ growth.

This video demonstrates a method to establish a three-dimensional tumor spheroid and T cell co-culture. An agarose cast with microwells containing tumor spheroids is prepared, followed by the addition of T cells. After incubation, this setup allows studying the interaction of T cells with tumor spheroids in a controlled three-dimensional environment.
FAQs
Cell–cell adhesion brings neighboring cells together, while extracellular matrix production helps organize and reinforce the aggregate. Compaction then reduces the space between cells and contributes to structural stability. These processes are important because they determine whether a cluster remains cohesive enough to support three-dimensional studies of cell interactions, tissue organization, and cellular responses.
As a spheroid becomes larger and more compact, oxygen, nutrients, and signaling molecules can distribute unevenly through the aggregate. These gradients create local differences in the cellular environment that are not represented as strongly in flat cultures. Studying those differences helps bioengineers examine how cells respond to spatially varying conditions within tissue-like structures.
Flat cultures do not reproduce the same three-dimensional organization or degree of cell–cell contact found in many tissues. Spheroids provide a setting in which cellular interactions, extracellular matrix production, compaction, and internal gradients can occur together. Consequently, researchers can assess tissue behavior, viability, and responses in an environment considered more physiologically relevant.
Formation is encouraged when cells are placed in nonadherent or confined conditions that limit attachment to a flat surface and favor cell–cell contact. Under these conditions, adhesion, matrix production, and compaction can drive clustering and stabilization. Researchers can then examine aggregate organization, cellular viability, and the resulting three-dimensional behavior rather than relying only on surface-grown cultures.
In bioengineering, cell spheroids support tissue engineering and regenerative research by providing compact three-dimensional systems for studying organization and cell interactions. They also serve as models for disease research and drug screening. These applications allow investigators to examine viability and cellular responses within aggregates that reproduce important spatial features of tissue-like environments.
Researchers can evaluate how cells interact, remain viable, produce extracellular matrix, and respond to gradients of oxygen, nutrients, and signaling molecules. The aggregates also reveal how compaction and three-dimensional organization influence tissue behavior. Such information is useful when interpreting disease-related responses, assessing candidate treatments, or investigating how engineered cellular structures develop.
