Primary cells come from donor tissue. They closely reflect in vivo biology, but they are limited in passage number and can show donor variability. Cell lines can be cancer-derived or immortalised, for example via hTERT or viral antigens. They can be expanded indefinitely and give consistent results across experiments. Choose primary cells when physiological relevance matters most. Choose cell lines when reproducibility matters most.
Cell lines, primary cells and 3D culture systems for physiologically relevant models
The cells you choose set the ceiling on every result that follows.
The right model comes first, then keeping it healthy takes media and reagents matched to it. Cell lines give you a defined, expandable model that behaves the same way across experiments. Choose from cancer-derived lines, immortalised normal-tissue lines, and disease-relevant models across human, mouse, rat, hamster, and canine backgrounds, alongside engineered lines with stable knockdown or knockout.
Primary cells come straight from donor tissue, giving you biology closer to in vivo than any cell line. They cover a wide range of tissue types, each matched to media that keeps your cultures functional.
iPSC-derived cells and cell immortalisation reagents extend this range. Reach for them when you need a human genetic background or a custom immortalised line of your own.
3D cell culture moves your model beyond a flat monolayer. Hydrogels, bioinks, and specialized culture plates support organoids, spheroids, and other 3D formats that track tissue architecture and drug response.
Basal media, sera, and transfection reagents support every one of these formats.
Applications
In vitro disease modelling
Primary cells, iPSC-derived cells, and patient-derived lines recapitulate disease phenotypes in culture, giving you human-relevant models for mechanistic work in oncology, neuroscience, and metabolic disease.
Drug discovery and toxicology
Defined cell culture systems let you screen compound libraries against the right cell types under reproducible conditions. Viability, apoptosis, and metabolic activity endpoints support lead selection and safety assessment.
Gene editing and functional genomics
Cells carrying CRISPR edits, stable knockdowns, or reporter constructs let you dissect gene function and pathway regulation in a defined cellular context.
3D tissue and organoid modelling
3D cell culture systems built from hydrogels, bioinks, and specialized culture plates support organoids and spheroids that better reflect native tissue architecture and drug response than flat monolayers.
Stem cell and regenerative medicine research
iPSC-derived cells give a defined human genetic background for differentiation studies, disease modelling, and early-stage regenerative medicine work.
Custom cell line development
Cell immortalisation reagents and engineered lines with stable knockdown or knockout let you build a bespoke model when an off-the-shelf line does not fit your assay.

2D monolayer culture is straightforward and cost-effective for high-throughput assays. 3D formats include spheroids, organoids, and hydrogel-embedded cultures. They better replicate tissue architecture, nutrient and oxygen gradients, and cell-cell contacts found in vivo. This makes them more predictive for drug penetration, toxicity, and invasion assays. Pick 3D when the spatial context drives your endpoint.
Mycoplasma testing every two to four weeks by PCR is the most important routine check. Mycoplasma is common and invisible, and it alters cell metabolism and gene expression. Confirm cell line identity by STR profiling when a line first arrives, and again after any suspicious phenotypic change. Trypan blue exclusion before each passage tracks culture health.
Xeno-free culture removes animal-derived components, such as animal serum and Matrigel, and replaces them with defined human or recombinant alternatives. It matters most for iPSC-derived cell culture, primary cell expansion, and any application where the cells are intended for clinical translation. Animal-derived components can introduce lot-to-lot variability and potential xenogeneic contamination.
