Three-Dimensional Culture Systems: Spheroids and Organoids

2026
Three-dimensional (3D) culture systems, including spheroids and organoids, support New Approach Methodology (NAM)-aligned research by providing more physiologically relevant models than conventional two-dimensional cell cultures. Because they more closely resemble the structure and cellular interactions of tissues and organs, these systems can provide physiologically relevant data before advancing to animal studies. Spheroids as Disease and Drug Screening Models Spheroids are generated when one...

Aqueous two-phase systems were used to simultaneously pattern multiple populations of cells. This fast and easy method for cell patterning takes advantage of the phase separation of aqueous solutions of dextran and polyethylene glycol and the interfacial tension that exists between the two polymer solutions.

Cell growth rate is a regulated process and a primary determinant of cell physiology. Continuous culturing using chemostats enables extrinsic control of cell growth rate by nutrient limitation facilitating the study of molecular networks that control cell growth and how those networks evolve to optimize cell growth.

Traditional, two dimensional cell culture techniques often result in altered characteristics with respect to differentiation markers, cytokines and growth factors. Three-dimensional cell culture in the rotating cell culture system (RCCS) reestablishes expression of many of these factors as shown here with an extravillous trophoblast cell line.
FAQs
Co-culture systems can distinguish effects that require physical contact from those mediated by diffusible signals. In a mixed monolayer, tumor cells can interact directly with stromal, immune, endothelial, or other supporting cells while also sharing soluble factors. A membrane-separated arrangement limits direct contact but permits communication through permeable compartments, helping researchers interpret which interaction route contributes to a cancer-related response.
Cytokines and growth signals exchanged between tumor and supporting cells can alter several cancer-relevant behaviors, including proliferation, invasion, survival, and treatment response. These effects arise from communication within the modeled cellular environment rather than from tumor cells considered alone. Examining the resulting changes helps connect interactions with specific outcomes, such as enhanced survival or altered sensitivity to therapy.
Different formats provide different levels of experimental control over cellular interaction. Mixed monolayers allow direct contact and soluble communication together, whereas separated compartments linked by permeable membranes emphasize paracrine signaling while restricting physical contact. Comparing these arrangements helps researchers determine whether an observed cancer phenotype depends on contact, diffusible factors, or both, rather than treating all cell interactions as equivalent.
Researchers can pair tumor cells with a relevant supporting population, such as stromal, immune, or endothelial cells, then select a format that matches the interaction being examined. A mixed arrangement suits questions involving direct contact, while separated compartments are useful when communication through soluble factors is the focus. This design links the chosen cellular partners and physical arrangement to the experimental question.
These models can be used to examine changes in tumor-cell proliferation, invasion, survival, and response to treatment. Measuring such outcomes in the presence of supporting cells shows how cellular communication modifies cancer behavior compared with a tumor-cell-only context. The resulting observations can identify interactions associated with altered therapy response or other features of the tumor microenvironment.
In cancer research, co-culture approaches recreate selected interactions between tumor cells and surrounding stromal, immune, endothelial, or other supporting populations. This context supports investigation of how cellular exchanges influence tumor behavior and treatment response. Researchers can use the models to study mechanisms associated with resistance and to evaluate therapies under conditions that include microenvironmental communication rather than relying only on isolated tumor cells.
