The Growing Role of Organoids in Research
Organoids are transforming biomedical research. These three-dimensional, multicellular models mimic the architecture and function of real human tissues, making them invaluable for studying complex processes such as organ development, cancer progression, and regenerative therapies. Derived from stem cells or primary tissues, organoids maintain the spatial organization, cellular diversity, and functional activity of in vivo systems—all in a lab-controlled environment.
Because of their ability to mirror real biology, organoids are now widely used in areas such as neurodevelopmental studies, liver disease modeling, gastrointestinal research, and tumor drug screening. Whether modeling Alzheimer’s disease with brain organoids or testing chemotherapeutic responses in patient-derived tumor organoids, these systems are helping researchers bridge the gap between 2D cultures and animal models.
However, to access the full potential of organoid models, especially for downstream applications like imaging or molecular profiling, researchers must section these fragile structures without compromising viability or integrity. That’s where the Compresstome vibratome plays a vital role.
Sectioning Techniques for Organoids
Organoid sectioning poses unique challenges: their small size, soft structure, and embedded matrices make them difficult to handle with traditional tools like cryostats or rotary microtomes. Manual slicing introduces artifacts, while paraffin embedding can damage live cells. The Compresstome® vibratome, however, is designed specifically to preserve both structure and viability.
With its gentle compression system and adjustable slicing parameters, the Compresstome creates thin, uniform organoid sections—typically between 100–300 µm—without tearing, folding, or dehydrating the sample. Researchers can fine-tune speed, amplitude, and slice thickness to match the needs of delicate tissue types.
Key advantages include:
- Minimal mechanical stress, preserving cell-cell junctions and morphology
- Compatibility with live-cell workflows, including real-time imaging and viability assays
- Flexible embedding in agarose for diverse organoid shapes and sizes
This approach supports high-quality histology, immunostaining, electrophysiology, transcriptomics, and even transplantation assays. Whether the goal is to visualize brain cortical layering or map drug diffusion in tumor models, clean, reproducible sections are essential—and the Compresstome delivers.
Examples of Organoid Research
At Precisionary Instruments, we’ve had the privilege of supporting scientists using the Compresstome across many organoid-based studies. Our recently released Organoid Tissue Sectioning Protocol Manual outlines detailed methods for embedding, slicing, and incubating sections from brain, liver, intestinal, and tumor organoids.
Here are just a few ways labs are using our tools:
- Tumor Organoids: Oncology researchers use Compresstome-sectioned tumor organoids to test the penetration and efficacy of chemotherapies and targeted treatments. These thin sections enable better imaging of drug uptake and resistance markers.
- Liver Organoids: In hepatotoxicity studies, liver organoid slices prepared with the vibratome help monitor bile production, metabolism, and response to drugs over time.
- Brain Organoids: Neuroscience labs rely on our sectioning systems to reveal layered neural networks in brain organoids, using live-imaging or immunofluorescence to assess differentiation, signaling, or viral infection.
