Hepatocytes

Mature, Polarized & Functional

Cytochroma's hepatocytes reflect adult physiology, produce albumin Cytochrome P450  enzymes and are drug inducible.  They mimic the liver’s highly organised structure, making drug transporter and efflux studies more physiologically predictive.

All hepatocytes are derived from our unique iPS library containing distinct genetic backgrounds with commonly occurring polymorphisms in key cytochrome P450 genes.

Male and female models can be used to understand gender specific effects and detect toxicity in a global population ahead of clinical trials.

  • Polarized bile canaliculi structures

  • Lipid-loading capability for steatosis models

  • Ideal for 2D and 3D liver systems, high-throughput toxicology, and metabolic disease studies

  • Batch-to-batch consistency, animal-free, scalable

  • Available from six healthy donor backgrounds. 

Perfect for:

DILI screening, drug metabolism assays, and modelling MAFLD, MASH, fibrosis, inflammation and steatosis.

 Endothelial Cells

Predict vascular toxicity, barrier disruption, and inflammatory responses

Endothelial cells are involved in multiple processes including blood flow, vascular permeability or angiogenesis. Cytochroma can manufacture endothelial cells from the iPSC line that best fits your project via a controlled and scalable process. Custom assays can be developed with this fully functional cell model to screen drug-induced effects on endothelial barrier permeability or 3D capillary tube formation.

  • Expression of vascular markers (CD31, VE-Cadherin, vWF)

  • Form tight junctions and capillary-like networks

  • Respond to inflammatory stimuli (e.g., TNFα)

  • Support complex co-culture systems

  • Available from six healthy donor backgrounds. 

Perfect for:

Liver-on-a-Chip, vascularized spheroids, fibrosis progression models

Macrophages

Model Liver Inflammation with iPSC-Derived Macrophages

Cytochromas macrophages mimic primary human macrophages, offering a scalable platform to study inflammation, immune responses, and tissue remodeling. They can be integrated into complex tissue models to assess immune-driven toxicity and improve preclinical relevance.

  • Express CD206, CD14, CD11b, and CD86

  • Secrete inflammatory cytokines (TNFα, IL-1β, IL-6) in response to stimuli

  • Functional phagocytosis assays

  • Engineered for use in multi-cellular liver models

  • Available from three healthy donor backgrounds

Perfect for:

MASH inflammation models, immune-mediated liver injury studies, immunotoxicology

Cardiac Fibroblasts

Build complex Cardiac Models with iPSC Cardiac Fibroblasts

Cardiac fibroblasts play a role in regulating normal myocardial function, and in the myocardial remodelling that occurs with heart disease.

Cardiac fibroblasts are highly pure with low variability between lots, ideal for a variety of purposes. From co-culture with Cardiomyocytes for further maturation, aiding in the formation of engineered heart tissue to disease modelling, these versatile cells can accelerate your drug discovery research, high-throughput screening and toxicity assessments. Use on their own or with our isogenic iPSC-derived heart cell types to create complete heart models.

  • Ready-to-use post-thaw for streamlined workflows

  • Co-culture with Cytochroma’s Cardiomyocytes to model human cardiac tissue

  • Support applications in disease research, drug discovery, safety testing, and regenerative medicine
