IN VITRO TOXICOLOGY TESTING MARKET SEGMENTATION

BASED ON TYPES

• Cellular Assay: Cellular assays assess the living biological response of cells to other chemicals or drugs. Cellular assays are primarily used to study toxicity, proliferation, and gene expression in a laboratory environment.
• Biochemical Assay: Biochemical assays measure the activity of enzymes, protein interactions and metabolic functions using purified biomolecules. Because data from biochemical assay will relate to specific biochemical pathways, biochemical assays can yield definitive results regarding how compounds impact pathways.
• In Silico: In silico testing uses simulated and computational predictive models to evaluate toxicity and drug bio-interactions in vitro. Researchers can examine chemical libraries on a large scale without having to even physically use them.
• Ex-vivo: Ex-vivo are assays that use tissue or organs removed from living organisms to examine the toxic response in the tissue/organ. Ex-vivo actually fall between in vitro and in vivo.

BASED ON DOWNSTREAM INDUSTRY

• Systemic Toxicology: Systemic toxicology emphasizes the effects of toxicants to internal organs and systems beyond the skin after absorption. By evaluating how toxicants affect the internal organs of mammals, systemic toxicologists can identify damaging effects to organs such as the liver, kidneys, or nervous system.
• Dermal Toxicity: Studies for dermal toxicity measure the toxic effects of a chemical when applied to the skin. These studies are often conducted for cosmetic safety testing or chemical safety testing to ensure that skin and/or eye irritation and long-term skin damage does not occur.
• Endocrine Disruption: Endocrine disruption testing is used to identify chemicals that interfere with the function of hormone modifiers. It is typically performed to identify which substances alter the process of signaling internally through endocrine system mechanistic pathways and biological signaling associated with growth, reproduction, or metabolism.
• Ocular Toxicity: Ocular toxicity testing measure the amount of damaging effect a chemical or product has on the eye. Examples include pharmacological formulations like eye drops or cosmetics that are designed to be applied to the eye. Eye drops requiring a toxicological assessment to ensure a conditioning agent-like effect instead of an irritable effect.
• Others: Other examples of toxicological tests ancillary to systemic or dermal toxicity assessments include inhalation, reproductive, and genetic toxicity testing to provide safety data from a precise or comprehensive view in variables of chemical exposure and biological function.

BASED ON REGION

• North America: North America is the global leader in the advancement of systemic toxicology based on laboratory structure and regulatory support. Pharmaceutical companies typically invest and actively develop non-animal methods based on systemic animal methods to evaluate organ level toxicity in drug development.
• Europe: A significant number of groups in Europe are developing dermal toxicity testing, this is largely due to cosmetics laws governing the safety of cosmetic products and the use of animal testing models have been banned. The variety of in vitro skin models that are available and regulatory bans on the use of animals alleviates some of the ethical challenges associated with employing/using animal testing-associated new dermal toxicity tests.
• Asia: Asia is expanding research into endocrine disruption and mechanisms to measure variate level of endocrine disruption and increased focus on health and wellbeing drives this. Countries such as Japan and South Korea are also investing in predictive models for the detection of biological hormonal interference from chemicals in the industrialized and environmental contexts.
