Artificial intelligence (AI) plays a vital role in cell viability assays by introducing automation and improving accuracy. It provides real-time monitoring of assays, enabling researchers to make proactive decisions. Live-cell assays generate multiple data points from a single well over time. AI can enhance the efficiency, accuracy, and reproducibility of viability assays, allowing researchers to focus on result interpretation over conducting laborious manual tasks. Additionally, it can assist researchers in data interpretation, avoiding complex calculations. Thus, AI can overcome the significant challenges of conventional assay procedures.
Growing Cancer Research
The major growth factor for the cell viability assays market is the growing field of cancer research. The rising prevalence of cancer and its severity lead to increased cancer research activities. The World Health Organization (WHO) estimates that about 1 in 5 people develop cancer in their lifetime, and approximately 1 in 9 men and 1 in 12 women die from cancer. (Source - WHO) Researchers identify novel targets and biomarkers that are involved in disease progression. This enables them to design novel drugs and test those drugs for their cytotoxicity profile.
Lack of Qualitative Data
Cell viability assays provide only quantitative data. They are unable to distinguish between different forms of cell death or derive the mechanism of cell death. This leads to insufficient data about cell viability, restricting market growth.
What is the Future of the Cell Viability Assays Market?
The market future is promising, driven by the increasing demand for personalized medicines. Personalized medicines are developed to address rapidly changing demographics and deliver targeted treatment. Advancements in genomics also support the development of personalized medicines. Stem cells, gene therapy, monoclonal antibodies, and recombinant proteins are the most common examples of personalized medicines. Cell viability assays are essential for stem cell research to assess their cell health and proliferation, especially when evaluating treatments or culture conditions. These assays help quantify the number of live cells, providing insights into cell survival, metabolic activity, and potential cytotoxicity.
By product type, the reagents and kits segment held a dominant presence in the market in 2024. This segment dominated due to the continuous requirements of reagents and kits for assays. Several companies provide kits and reagents at affordable rates, enabling researchers to meet their research requirements. They are more cost-effective than instruments and do not require specialized infrastructure. They enable researchers to develop accurate and reproducible results.
By product type, the instruments & systems segment is expected to grow at the fastest CAGR in the market during the forecast period. Instruments provide advanced services and results, and are integral parts of cell viability assays. Technological advancements drive the latest innovations in instruments to derive accurate results. Instruments, such as microplate readers, fluorescence microscopes, flow cytometers, and cell imaging systems, aid in data analysis and interpretation.
By assay type, the metabolic activity-based assays segment held the largest revenue share of the market in 2024. This is due to the ease of measuring cell metabolites and the simple procedure. Metabolites are directly linked to cellular energy, the generation of cellular building blocks, and signaling pathways. Metabolic activity-based assays help researchers to measure glucose uptake, lactate, glutamine, oxidative stress, and dinucleotide detection assays. These tests assess enzymatic activity as a marker for cell viability. An increase in enzyme activity is an indication of enhanced cell proliferation.
By application, the pharmaceutical & biotech research segment contributed the biggest revenue share of the market in 2024. This segment dominated due to the growing research and development activities in the pharma and biotech sectors. New drug discovery and stem cell research necessitate cell-based assays to assess cell cytotoxicity. Cell viability assays are used to evaluate drug safety and efficacy, optimize culture conditions, and screen drug candidates. This enables researchers to identify potential drug candidates before testing on animals. The increasing emphasis of several government organizations on reducing animal testing potentiates the demand for cell viability assays.
By application, the clinical diagnostics segment is expected to grow with the highest CAGR in the market during the studied years. The rising prevalence of chronic disorders and the increasing demand for early disease diagnosis augment the segment’s growth.
