Cancer Cell Metabolism in Physiological Culture Conditions
Summary
Cancer cells reprogramme their metabolism to support accelerated proliferation, survival in adverse environments and resistance to therapy. Traditional two-dimensional cultures in supraphysiological media have revealed key pathways such as aerobic glycolysis and glutamine anaplerosis, yet often fail to mirror the nutrient gradients, metabolite concentrations and cell–cell interactions encountered in vivo. Recent advances emphasise the use of media formulated to match human plasma metabolite levels and the adoption of three-dimensional culture systems that recapitulate tumour architecture. These approaches unveil context-dependent shifts in central carbon metabolism, redox homeostasis and lipid utilisation that are obscured in conventional models. By aligning in vitro conditions more closely with physiological reality, researchers can better predict drug responsiveness, uncover novel metabolic vulnerabilities and refine therapeutic strategies. Integrating measurements of interstitial fluid composition, dynamic nutrient flux and oxygen availability holds promise for bridging the gap between cell culture findings and clinical outcomes, accelerating the translation of metabolic targets into effective anticancer treatments.

The graph below shows the total number of articles in cancer cell metabolism in physiological culture conditions across all publications each year (not limited to Nature Index journals).
Technical terms
Physiological culture medium: A cell culture formulation whose concentrations of amino acids, sugars, salts and other metabolites mimic those found in human plasma.
Three-dimensional (3D) culture: A cell growth system that allows cells to form spheroids or organoids, recreating cell–cell and cell–matrix interactions observed in tissues.
Interstitial fluid: The extracellular fluid that surrounds cells within tissues and through which nutrients and waste products diffuse.
Anaplerosis: The process of replenishing intermediates of the tricarboxylic acid cycle to sustain biosynthetic demands.
Pseudohypoxia: A cellular state in which hypoxia-related transcriptional programmes are activated despite normal oxygen levels.
Ferroptosis: An iron-dependent form of regulated cell death characterised by lipid peroxidation and membrane damage.
Hypoxia-inducible factor 1α (HIF1α): A transcription factor that mediates cellular adaptation to low oxygen by regulating genes involved in metabolism and angiogenesis.
