Stem cells are undifferentiated cells with the unique ability to self-renew and differentiate into specialised cell types.
They are essential for tissue repair, regenerative medicine, and disease modelling. Derived from both embryonic and adult tissues, stem cells are classified by their developmental potential, as totipotent, pluripotent, multipotent or unipotent, and each type requires tailored in vitro culture conditions to preserve their functionality and guide lineage outcomes.
Stem cell culture involves expanding or differentiating these cells under tightly controlled laboratory conditions. This process depends on the careful regulation of environmental parameters such as pH, oxygen concentration, nutrient supply, and growth factors. For pluripotent stem cells, including embryonic and induced pluripotent stem cells, the use of coated culture plates, feeder layers, and serum-free media helps to maintain pluripotency and prevent spontaneous differentiation.
To meet these demands, specialised tools can streamline and standardise stem cell culture processes. Ultra-low attachment culture surfaces such as PrimeSurface® promote uniform spheroid formation for organoid and 3D culture systems without cell adherence to the plate which leads to loss of 3D structures, improving reproducibility of representative cell behaviour in drug testing and toxicology.
Small molecules, such as kinase inhibitors or signal transduction modulators, help improve cell fate decisions by guiding self-renewal and differentiation pathways. Ready-to-use mixes like the CultureSure® CEPT Cocktail enhance cell viability by protecting against stress and DNA damage during cell passage. These formulations improve reproducibility across applications such as genome editing, organoid development, embryoid body formation, and single-cell cloning, making advanced stem cell research more consistent and efficient.
As the role of stem cells expands across clinical and research settings, becoming more important in disease modelling, regenerative therapies, and drug screening, optimised culture techniques supported by reliable reagents and products remains key to advancing both basic and translational research.
