Source: Ear, P. H., et. al. Establishment and Characterization of Small Bowel Neuroendocrine Tumor Spheroids. J. Vis. Exp. (2019)This video demonstrates the immunofluorescence staining of small bowel neuroendocrine tumor spheroids. The spheroids are fixed, permeabilized, and blocked and are then incubated with primary and secondary antibodies. A dye is added to stain nuclei before mounting and visualizing them under a fluorescent microscope.

Morphology, size and location of intracellular organelles are evolutionarily conserved and appear to directly affect their function. Understanding the molecular mechanisms underlying these processes has become an important goal of modern biology. Here we show how these studies can be facilitated by the application of quantitative techniques.

This manuscript describes a detailed protocol for phenotypic and quantitative analysis of resident macrophages from rat kidneys by flow cytometry. The resulting stained cells can be also used for other applications, including cell sorting, gene expression analysis or functional studies, thus increasing the information obtained in the experimental model.
FAQs
Three-dimensional organization allows cells within a spheroid to interact and establish spatial gradients, creating phenotypic differences across the aggregate. Characterization examines these differences through structure, size, morphology, viability, and molecular or immunostaining readouts. Together, these measurements show whether cells maintain tissue-like organization and how that organization changes under defined culture or treatment conditions.
Three-dimensional aggregates provide cell interactions and spatial organization that are not represented in a flat monolayer. As a result, changes in viability, morphology, organization, or functional state may emerge only when cells experience the aggregate environment. Comparing these readouts with two-dimensional cultures helps identify phenotypic responses that depend on three-dimensional structure.
Size, morphology, viability, organization, and functional state provide complementary evidence rather than a single measure of performance. Size and shape indicate structural changes, while viability shows cellular condition. Molecular or immunostaining analyses add information about phenotype and organization, helping distinguish a simple change in appearance from a broader biological response.
Spheroid phenotype characterization can reveal how cells respond to biomaterials and mechanical cues by tracking changes in structure, morphology, viability, organization, and functional state. These readouts connect the surrounding bioengineering conditions with the resulting tissue-like phenotype. The approach therefore helps assess whether a designed environment supports or changes the intended cellular organization.
A typical workflow combines imaging with measurements of spheroid size and morphology, followed by viability assays and molecular or immunostaining analyses. Imaging captures overall structure and organization, whereas viability assays assess cellular condition. Molecular readouts provide additional evidence about phenotype and functional state, allowing researchers to interpret treatment or culture effects across several complementary levels.
The approach supports development and quality control of tissue models and organoid-based systems, as well as regenerative medicine strategies. It also helps evaluate physiologically relevant platforms for disease research and therapeutic testing. By measuring responses to culture conditions, biomaterials, mechanical cues, drugs, or other treatments, researchers can determine whether a model develops the intended phenotype.
