AI Insight
Researchers have developed Microdomes, a micro-engineered platform consisting of dense arrays of dome-shaped microcavities that each hold a single organoid or spheroid in a fixed position. The design features narrow openings that allow medium exchange and staining while protecting fragile 3D cell cultures from shear stress during routine handling. The platform enables long-term culture of over 100 specimens per chip with full retention through multiple procedures, supports advanced imaging from overview to subcellular resolution, and allows the same specimen to be tracked and re-imaged across weeks without transfer or embedding.
Why it matters
This technology addresses major bottlenecks in organoid and spheroid research by standardizing handling, improving reproducibility, and enabling specimen-level traceability throughout the culture period. The compatibility with automated imaging and AI-based analysis could accelerate organoid-based drug screening, disease modeling, and quality control in precision medicine applications.

Three-dimensional cellular models such as organoids and spheroids hold major promise for developmental biology, disease modelling and precision medicine, yet their large-scale production and analysis remain constrained by handling-induced shear stress, sample fragility, positional instability and limited compatibility with advanced imaging workflows. Here, we introduce Microdomes, dense arrays of open-top, dome-shaped microcavities. Each cavity holds a single specimen in its own miniature aquarium, accessed through a narrow apical opening that admits cells, medium, matrix and staining reagents while shielding it from the shear generated during routine pipetting. Each Microdomes chip accommodates more than 100 spheroids or organoids, supporting diverse cell types, co-culture formats and both matrix-free and matrix-embedded culture. All specimens are retained through prolonged culture, repeated medium exchange, fixation and immunostaining. Because every specimen occupies a fixed, addressable position against a thin transparent film, the same spheroid can be relocated and re-imaged over weeks of culture and across microscopes, from array-wide overviews to subcellular details, without transfer, embedding or other perturbation. Microdomes also support AI-based automated segmentation, from whole-spheroid outlines to individual nuclei in 3D, using common image analysis software. Microdomes thereby turn each array into a self-contained quality control unit, providing specimen-level traceability that organoid production pipelines currently lack.
