Streamline your research with standardized, ready-to-use, primary cell-based 3D liver models in high-density culture format.
Regulatory and funding bodies like the FDA and NIH are actively driving a significant shift toward human-relevant, innovative models over traditional models for drug and agrochemical safety assessment. As a result, the demand for 3D liver models that are physiologically relevant, scalable, and reproducible is greater than ever.
Yet for many labs, building physiologically relevant 3D liver spheroids remains a major bottleneck. In-house development requires significant time, resources, and expertise to validate cells, optimize culture conditions, and ensure consistent quality and performance. The result? Batch-to-batch variability, limited scalability, and delays that compromise both data reliability and translational outcomes.
Skip the complexity, variability, and time investment of developing 3D liver models from scratch. Our assay-ready 3D InSight™ Human Liver Microtissues are pre-qualified, physiologically relevant, and ready to use out of the box, empowering your team to generate high-quality, human-relevant data from day one.

Achieve more accurate predictions and gain meaningful insights into broad human population responses with our 3D InSight™ Human Liver Microtissues, a physiologically relevant in vitro co-culture of human primary hepatocytes pooled from 5 male and 5 female donors, combined with non-parenchymal liver cells from 1 donor, which includes but is not limited to Kupffer & endothelial cells.
Extend your experimental timelines without compromising data quality. Our 3D InSight™ Human Liver Microtissues maintain high viability and consistent albumin secretion for up to 4 weeks, enabling reliable long-term and repeated-treatment studies adaptable to your needs.
Conduct long-term functional assays confidently using 3D InSight™ Human Liver Microtissues, which maintain stable cytochrome P450 (CYP) activity for an extended period. This enables robust and accurate assessments in long-term liver safety, efficacy, drug metabolism, or pharmacokinetics studies.
Capture human-relevant immunological responses in your studies by using assay-ready 3D liver models that incorporate primary human Kupffer cells and liver-resident T cells with primary human hepatocytes, closely replicating the native liver microenvironment.
Each well of the Akura™ 96 spheroid microplate contains a ready-to-use liver spheroid with consistent size and morphology. Our 3D Liver spheroid shows significant uniformity across high cell culture density plate format, making it ideal for multi-concentration treatment studies, throughput screening, and studies that demand scalability.
Our streamlined weekly automated production process and rigorous pharma-grade quality control ensure consistent, uniform spheroids across batches. Using large cryopreserved cell lots ensures minimal batch-to-batch variability – so you can confidently plan long-term studies and repeat experiments, knowing you will generate the same high-quality, reproducible data every time.

Primary human hepatocytes (PHHs) are liver cells isolated directly from donated human liver tissue. Unlike immortalized cell lines, PHHs retain the native metabolic functions, enzyme expression (especially cytochrome P450 enzymes), and transporter activity of the human liver. This makes them the gold standard for in vitro liver research, particularly in drug metabolism, toxicity, and pharmacokinetics studies.
Their physiological relevance enables more accurate predictions of how a compound will behave in humans—something that simpler models or animal-derived cells often fail to capture.
In 2D hepatocyte cultures, liver cells are grown as a flat monolayer on a plastic surface. While simple to handle, these cells rapidly lose liver-specific functions, such as cytochrome P450 activity and albumin production, limiting their use for long-term or predictive studies.
In contrast, 3D liver spheroids—such as InSphero’s 3D InSight™ Human Liver Microtissues—are self-assembled co-cultures of hepatocytes and non-parenchymal cells that mimic the structural and functional complexity of the liver. These 3D models maintain liver-specific functions over several weeks, support long-term and repeated-dose studies, and better replicate the in vivo liver environment, enabling more human-relevant and translational insights.
Once received, the 3D liver microtissues maintain high viability, albumin secretion, and stable CYP450 activity for up to 4 weeks, supporting short- and long-term experiments, including repeated dosing.
Each production batch of assay-ready 3D InSight™ Human Liver Microtissues is manufactured using a standardized, controlled process to ensure consistency. Every batch undergoes rigorous quality control, including checks for spheroid size, ATP content, and confirmation of one spheroid per well.
To support transparency and reproducibility, each plate is shipped with a certificate of analysis (CoA).
They are pre-aggregated, viable 3D liver spheroids composed of primary human hepatocytes and liver non-parenchymal cells (including but not exclusively Kupffer and endothelial cells), delivered in Akura™ 96 spheroid microplates (1 spheroid/well).
Ready for immediate use upon arrival. No thawing and seeding.
The assay-ready 3D InSight™ Human Liver Microtissues are delivered in Akura™ 96 spheroid microplates, optimized for 3D spheroid culture—no transfer is needed.
To maintain viability and function, you should use the appropriate 3D InSight™ Liver Maintenance Medium (Tox, AF, or INF), provided or specified with your order.
Donor lot changes at InSphero are infrequent, thanks to the use of large pooled donor lots, enabling consistent supply for long-term studies.
To ensure data consistency, InSphero follows a standardized production process and performs comprehensive lot validation before a donor lot is released for production. Each lot is evaluated for key hepatic and non-parenchymal cell markers (e.g., albumin, ASGR1, CK18, BSEP, CD68, CD31, α-SMA), and functionally characterized over time for ATP levels, albumin secretion, cytochrome P450 activity, and IL-6 profiling.
Only lots that meet strict performance criteria are approved for production, ensuring high-quality, consistent data across experiments.
The microtissues are produced from pooled hepatocytes from 5 female and 5 male donors, combined with non-parenchymal cells from a single donor. This approach minimizes donor-specific variability and ensures a reliable, population-relevant response across batches. When a donor lot change is planned, InSphero informs customers in advance so they can perform bridge studies if necessary, ensuring continuity and comparability in their data.
Yes, InSphero offers customized 3D liver microtissues tailored to specific research needs. Available variations include:
These tailored models are developed in close collaboration with customers and follow the same rigorous quality standards as standard assay-ready microtissues, ensuring high reproducibility and physiological relevance.
