COMPARING IN VITRO INNOVATIONS: Spheroids, Organoids, and Organs-on-Chips Different 3D cell cultures provide complementary approaches to mimic human biology, offering new insights into disease modeling, drug discovery, and regenerative medicine. By Marnie Williams& Designed by Erin Lemieux Spheroids Hanging Drop Method Cell suspension dispensed onto a petri dish Flip lid to form hanging drops Cells aggregate Spontaneous Formation on Non-Adhesive Surfaces Adherent culture Seedling in attachment plate Spheroid formation in suspension Hydrogel (scaffold-based) Seedling mixed with hydrogel Single spheroid formation Spinner Suspension Culture Scientists generate spheroids using techniques that allow controlled formation and uniform size for standardized experiments (1,2). Spheroids provide drug discovery laboratories with robust models in a controlled environment. Their uniformity and ease of handling makes spheroids particularly suitable for imaging and analysis workflows in drug development pipelines. Spheroid formation Spheroid formation from seedlings in spinner flask Organoids Researchers develop organoids by differentiating stem cells under controlled conditions with extracellular matrix scaffolds and growth factors to guide organ-specific development (3). These models mimic organ structures, enabling cellular-level drug studies and advancing personalized medicine. Organs-on-Chips Intestinal epithelial cells Bacterial cells on the inside of a layer of intestinal cells Cerebral organoid Lung organoid Liver organoid Mammary gland organoid Stomach organoid Intestinal organoid A layer of intestinal epithelial cells, which could be housed in an organ-on-a-chip model. Microchamber in Microchannel in -Microchannel out Microchamber out An organ-on-a-chip, containing a network for microchannels, a loading well, and inspection areas. Laboratorians create organs-on-chips using microfabrication to embed living cells in precisely engineered environments that replicate physiological conditions like fluid flow and mechanical forces (5). These systems enable high-resolution analysis of drug interactions and toxicity, supporting human-specific research and reducing reliance on animal models.
