Here, we describe a rapid and flexible protocol for the formation of 3D cell spheroids through cell aggregation. This is easily adapted to multiple cell types and is suitable for use in a variety of applications including cell migration, invasion, or anoikis assays, and for imaging and quantifying cell-matrix interactions.

This video demonstrates the transformation of human pluripotent stem cells (hPSCs) into spherical brain organoids. By using specific inhibitors, the hPSCs are guided to differentiate towards a neuronal lineage, forming neuroectodermal colonies. Special growth factors are then introduced, which encourage the self-organization and proliferation of the colonies, ultimately leading to the formation of spherical brain organoids.

Chondrogenesis from stem cells requires fine tuning the culture conditions. Here, we present a magnetic approach for condensing cells, an essential step to initiate chondrogenesis. In addition, we show that dynamic maturation in a bioreactor applies mechanical stimulation to the cellular constructs and enhances cartilaginous extracellular matrix production.

The therapeutic potential of mesenchymal stem/stromal cells (MSCs) is well-documented, however the best method of preparing the cells for patients remains controversial. Herein, we communicate protocols to efficiently generate and administer therapeutic spherical aggregates or 'spheroids' of MSCs primed under xeno-free conditions for experimental and clinical applications.
FAQs
During aggregation, gravity brings suspended stem cells into proximity, while cell-cell adhesion helps stabilize their contacts. As these interactions continue, cells compact into a coordinated three-dimensional structure rather than remaining dispersed. This combination of physical concentration and biological adhesion is important because it establishes the architecture needed to examine cell signaling and organization in a tissue-like setting.
Cell number, culture conditions, and aggregation time are the main factors identified as shaping spheroid size and uniformity. Changing the number of starting cells can alter the final cluster dimensions, while the surrounding culture conditions influence how consistently cells assemble. Monitoring aggregation time also matters because the extent of compaction develops as cells remain together.
A three-dimensional cluster preserves spatial relationships that are difficult to examine with isolated cells or flat cultures. This organization can improve the study of cell signaling, tissue organization, and interactions associated with nervous system development. The added architecture therefore provides a context for investigating neural processes beyond what cell behavior alone can reveal in less organized systems.
Stem Cell Spheroid Aggregation provides an organized three-dimensional starting structure for neural differentiation and brain organoid development. The compact arrangement creates a setting in which cells can interact within a shared architecture, supporting investigation of nervous system development. In this context, spheroids serve as a foundation for building more complex models rather than as an endpoint by themselves.
Researchers can place stem cells in low-attachment wells, hanging drops, or other nonadherent conditions so that cells do not readily attach to a surface. Under these settings, gravity concentrates the cells and cell-cell adhesion promotes assembly. The selected approach can then be evaluated by considering the resulting cluster size, uniformity, and aggregation time.
Neural stem cell spheroids can support brain organoid development, disease modeling, and drug testing. Their three-dimensional organization also enables studies of cell signaling, tissue organization, and interactions relevant to nervous system development. These applications make the approach useful when researchers need a model that captures spatial cellular relationships rather than examining neural cells only as isolated populations.
