Pluripotent stem cells are directly inoculated as single cells into the CEROtube. During the self-aggregation the cells form homogeneous aggregates which can be expanded over many passages. The biomass increases significantly while only ~2min per day hands on time is required.

The resulting stem cell 3D aggregates can be processed directly for differentiation e.g. organoids or any other downstream application in 3D or 2D assay development.

Hepatitis Virus Research Model - Spheroids

The advent of long-term three dimensional cell culture holds a great promise in disease modeling and drug discovery. The cells kept in a 3D environment have the ability to mimic tissue-like structures more efficiently than in traditional 2D monolayer cultures. However, many scientist are struggling with many technical limitations when working with spheroids in long-term cultures.

The CERO 3D Incubator & Bioreactor is a revolutionary technology enabling scientists to perform experiments they were not able to do before.

  • No necrosis and apoptosis
  • Viability in long-term culture > 80 days
  • Improved maturation
  • Long-term proliferation
  • High homogeneity
  • High yield

Virus Research

CERO 3D Incubator & Bioreactor enables growth and maturation of spheroids without necrosis and apoptosis while other technologies fail. Therefore, CERO 3D allows to maintain state-of-the-art 3D cultures of Huh7 hepatic cell line (see figure below). The disposable CEROtubes with Hepa filter allow safe virus experiments.

Virus Research CERO

Spheroid from hepatocyte cell line was matured for 20 days prior to exposure to HCV. Infection spreading (rate) was controlled after 24, 48 and 72hours (brown staining)

Cultivating hepatocyte spheroids in CERO considerably improves expansion, differentiation, maturation and hepatic virus infection compared to monolayer culture. Our research takes advantage from healthy cells even from long-term cultures in CERO. Moreover, we are now able to perform 3D long-term culture of human tissue specimen in CERO - a paradigm shift.

Cardiac Tissue Model

Beating Cardiac Bodies – a complete workflow

Stem cell derived cardiomyocytes gain more and more attention in the field of cardiovascular research, disease modeling and drug development.

The CERO 3D Incubator & Bioreactor platform allows the workflow with stem cell expansion in homogeneous aggregates followed by direct induction into a high number of beating cardiac bodies. The expansion of pluripotent stem cells and subsequent cardiac induction/differentiation in CERO 3D results in a much higher cell quality, homogeneity, integrity and yield compared to traditional orbital shakers.

Cardiac Tissue Model

CERO 3D versus Orbital shaker – differentiation of murine embryonic stem cell derived cardiomyocytes 3, 8 and 13 days after cardiac induction.

  • Homogeneous 3D aggregates in suspension
  • Expansion and differentiation in the same CEROtube
  • Easy to handle & standardize
  • Highest yield
  • No substrate required
  • More relevance for drug treatments
  • More relevance for disease modeling

Purified and homogeneous cardiac bodies generated in CERO 3D Incubator & Bioreactor are a perfect tool for disease modeling and drug discovery. The pure cardiomyocytes can also be used in 2D downstream monolayer applications.

The overarching aim of all our studies is the identification and development of clinically relevant therapeutic agents for the treatment of human heart disease. To that end we utilize human self-organised cardiac organoids for high throughput drug screening and in vivo genetic models of human congenital disease, as our experimental platform, in combination with adeno-associated virus (AAV) and anti-sense RNAs as therapeutic agents. The CERO 3D has considerably simplified our cardiac organoid generation workflow and enabled us to scale-up organoid production significantly. Organoids generated with CERO 3D reveal improved cellular organisation, and display uniformity and consistency within and across production batches.

Moreover this 3D cultivation system substantially improves viability, maturation and contractility, therefore provides a reliable tool for cardiovascular therapies.

Remarkably, the organoids have also a predictive capacity for in vivo response.

  • Reduced costs and time
  • Increase size & lifespan
  • Optimal nutrition & gas diffusion
  • Free floating, no shear forces
  • High homogeneity and yield
  • Multiplexing organoidogenesis

Increase cellular, structural and functional complexity of organoids.

There are also stem cells markers like Lgr5 and Sox2.

The generation of gastric organoids is a crucial step in the study of Helicobacter pylori infection and gastric carcinogenesis. The CERO 3D Incubator & Bioreactor allows the generation in a much more efficient, reproducible, physiological and cost efficient way compared to any other approach

Personalised and precision medicine

The progress in the development of molecular target therapies has improved the outcome in “in vivo”, however it is because of the tumor heterogeneity in patients that limits the efficiency of those drugs. Thus, to increase the relevance of “in vitro” models, it is particularly important to develop a reliable platform for growing primary tumor cells in a 3D in vitro model, like patient-derived xenografts or organoids. The CERO 3D Incubator & Bioreactor evolving a state-of-the-art dynamic culture system, accelerates precision medicine of primary tumor cells. The CERO 3D offers an efficient and reproducible approach to grow and maintain viable cancer cells in a CERO 3D Incubator & Bioreactor.

Our group is focusing on primary tumor cells grown on 3D polymer scaffolds. For that we are using CERO 3D to develop a model of drug development and precision medicine. It is particularly important that the cells are viable and proliferating in 3D complex structures as seen in tumor tissues. With the CERO 3D we are implementing and developing tools for patient-specific tumor therapy. Furthermore, the cancer cells isolated from fresh tumor biopsies make treatment optimization possible before a therapy is initiated. Here, CERO 3D incubator & bioreactor enables us to develop personalized medicine in a 3D cell culture model.
