In Vitro Toxicology Testing Market Growth Factrors

Opposition to Animal Testing

Animal testing has traditionally been the foundation for new chemical safety assessments. Preclinical animal testing is required to screen potential drug candidates, which is time-consuming and expensive. In the aerospace, biomedical, automotive, consumer product testing, military, cognitive research, and agricultural sectors, over 100 million animals are used for labor; 95% of these animals are not legally protected. However, several nations have recently pushed for a ban on chemical testing using animals.

Additionally, it is believed that when taking into account typical low-dose exposure, the traditional animal-based risk assessment methodologies are insufficient to evaluate the possible harm associated with any particular chemical thoroughly. Therefore, new prediction and testing models built on in vitro and computer modeling are needed for a more effective safety evaluation.

Ongoing Developments to Advance Toxicology Research

Regulatory agencies have become increasingly receptive to in vitro and alternative toxicology testing methods in recent years. The development of 3D cell culture due to technological advancements enables in vitro safety testing of new compounds. Researchers are developing animal-free technologies such as direct peptide reactivity assays, ARE-Nrf2 Luciferase assays, and the Human Cell Line Activation Test (h-CLAT). This market is also influenced by the expanding trend of outsourcing toxicology testing services. High-throughput chemical toxicity testing has been investigated due to new food additives and food contact substance development innovations. Constrained financial resources have prompted the adoption of cost-effective technologies for animal-free in vitro high-throughput screening (HTS).

Market Restraining Factors

Lack of in Vitro Models

The investigation of immunotoxin effects relies significantly on various animal models to characterize sensitization and immunosuppression. In vitro models are promising for advancing toxicological research; however, developing in vitro models, such as 3D constructs, is laborious and requires attentive care to preserve specificity and physiology similarity with the host. This is the case even though in vitro models have substantial potential for advancing toxicology research. In addition, if the development of tissue constructs does not go as intended, there may be substantial financial and time losses.

Market Opportunities

More Toxicology Databases Become Available to Businesses

The desire to expedite the toxicological examination of compounds, utilize fewer animals, and use less expensive tools has significantly impacted predictive toxicology and structure-based approaches. To increase the effectiveness of predictive toxicology techniques, the discipline requires access to the largest corpus of preliminary toxicological data, which must also be comparable and interoperable.

The efficient use of alternative toxicological testing methods will be aided by databases that contain information on chemical safety profiles, modes of action, genetic effects, fatal dose information, diverse formulations, and toxicogenomic data. These databases will also minimize animal testing requirements because they eliminate the necessity for repeated toxicity experiments on the same substances for safety evaluation.
