Streamlining and Simplifying Advanced Cell Models for Life Science Research
Cells are the building blocks of all organisms. Understanding the biology of cells and their interactions at the molecular level is the foundation of biomedical and life science research. Utilizing cells as models is an established approach for drug discovery, whereas their use as therapeutics is a rapidly growing approach.
More than 90% of therapeutic candidates fail to make it past phase III clinical trials, mainly due to their lack of efficacy. The use of 3D and stem cell-based models better recapitulate the pathobiology of diseases and offer in-depth predictive insights that can translate into positive clinical outcomes.
In recognition of this, the U.S. Food and Drug Administration (FDA) Modernization Act 2.0 allows scientists to now use cell-based models as alternatives to animal testing for drug applications.
Advanced cell models - such as organoids, spheroids and 2D stem cell-based models - are revolutionizing biomedical research and drug discovery. However, they come with several challenges:
- Reproducibility: Different labs may use different protocols, leading to variations in cell models. This can affect the reproducibility of the experiments and the validity of the results.
- Standardization: A lack of standardization in the methods used to create and maintain cell models can lead to inconsistencies in the quality and characteristics of models.
- Complexity: Advanced cell models are complex, making them more difficult to work with and interpret results.
- Cost: Advanced cell models are expensive to create and maintain, limiting their use in some research settings.
- Lack of vascularization: Without vascularity, models have limited ability to accurately mimic the in vivo environment.
- Scaling up: Providing sufficient quantities for high-throughput screening
- Long-term culture: Maintenance of cell viability and function over long periods
- Validation: There is a need for more validation studies to confirm that these models accurately represent human biology and disease.
Sartorius addresses these challenges and more with cutting-edge analytical solutions that streamline advanced cell model R&D workflows and provide translational insights that translate into clinical outcomes for patients in need.

3D Workflow/Process Diagram
3D cell models such as organoids and spheroids more closely recapitulate human cellular ecosystems which greatly improves clinical translation of new treatments.
The goal of in vitro 3D cell culture is to enable more physiologically relevant and translational models in a wide range of biomedical applications including disease modeling, drug discovery and screening as well as personalized medicine. Through comprehensive characterization, scientists can develop a deeper understanding of biology, ensure more robust maintenance of stem cells during extended cultures and monitor cells at every step of the 3D organoid and spheroid workflow.
What are Organoids and Spheroids?
Organoids are self-organizing, three-dimensional systems which retain many physiological characteristics of the native tissue from which they are derived. Accordingly, these miniaturized models have significant advantages over the use of traditional immortalized cell lines in providing accurate information on human disease modelling and can be used in the fields of drug screening, disease modeling, personalized medicine and many others.
Spheroids are simpler structures and less differentiated but still aggregation of one or more cell types in 3D cell cultures.

Frequently Asked Questions
Organoids are defined by three key characteristics: self-organization, spatially restricted cell fate decisions, and ability to perform at least one function observed in in vivo organ tissue.
Spheroids are also 3D cell culture models, but they represent simple structures of typically the same cell types thus providing a versatile tool for translational research and disease modelling. There is a higher order self-assembly in organoids as opposed to spheroid cultures, and the former is more dependent on a matrix for its generation.
The application with techniques initially developed for analysis with 2D cultures and 3D culture production and specification are seen as main challenges. Still limited by the technologies used to characterize these complex cell models and may introduce variability due to lack of environmental control and inadequate 3D Cell Culture protocols that compromise organoid or spheroid cell health.
The CellCelector Flex platform enables gentle picking of a wide range of organoid sizes, ranging from 80 μm to 3.5 mm with exceptionally low (1 μL) injection volumes of surrounding media into either 100% hydrogel, liquid media or any other medium. It automatically measures morphology before and after the picking and transfer to prove that the organoids retain their morphology and structure due to the very gentle transfer method.
Real-time tracking of changes in organoid eccentricity (object roundness) and darkness (object brightness) with the Incucyte® Live-Cell Analysis System enables rapid, unbiased assessment of optimal culture passage periods.
The iQue®3 spheroid immune cell killing (ICK) workflow measures subset analysis and cytokines quantification to examine the activation, killing, exhaustion, and memory profiles of T cells during co-culture with single spheroids. The workflows utilize the iQue®3 High-Throughput Screening Cytometer with associated suite of T cell characterization reagent kits, and validated spheroid washing and dissociation protocols to provide an end-to-end solution.
