The fullest potential for in vitro evaluation of toxicity will be realised in the context of the process of assessing the risk of human toxicity. This article is an attempt to clarify what contributions can be made by in vitro tests and what types of in vitro test can best be used. In vitro tests are clarified according to the type of biological endpoint evaluated, first into tests for general (‘basal’) cytotoxicity and, secondly, into tests for differentiated cell function. The role of each type of test is analysed and it is suggested that tests for general cytotoxicity, as opposed to differentiated function, are difficult to interpret in terms of in vivo toxicity. A general approach to evaluating in vitro tests is described, and a strategy for using these tests is proposed.

In many organs of the human body, there are effective physiological barriers which contribute to regulation of the uptake, transport and secretion of endogenous and exogenous materials. ECVAM is involved in the development of several in vitro models for detecting damage to various barriers, including, the renal epithelium, the intestinal barrier, and the blood–brain barrier, after acute and chronic exposure to chemicals and products of various kinds. Long-term toxicity testing is an important issue in toxicology. At present, there are no generally accepted in vitro models available for replacing chronic testing in animals. Under chronic exposure conditions, the cellular response is greater than that which can be predicted in the standard cytotoxicity models. Therefore, the approach to predicting chronic toxicity will need to involve more-complex in vitro models. Several currently available in vitro long-term toxicity systems are under evaluation.

Studies on potential toxicity of engineered nanoparticle (ENP) in biological systems require a proper and accurate particle characterization to ensure the reproducibility of the results and to understand biological effects of ENP. A full characterization of ENP should include various measurements such as particle size and size distribution, shape and morphology, crystallinity, composition, surface chemistry, and surface area of ENP. It is also important to characterize the state of ENP dispersions. In this study, four different ENPs, rutile and anatase titanium dioxides and short single- and multi-walled carbon nanotubes, were characterized in two dispersion media: bronchial epithelial growth medium, used for bronchial epithelial BEAS cells, and RPMI-1640 culture media with 10% of fetal calf serum (FCS) for human mesothelial (MeT-5A) cells. The purpose of this study was to determine the characteristics of ENPs and their dispersions as well as to compare dispersion additives suitable for toxicity tests and thus establish an appropriate way to prepare dispersions that performs well with the selected ENP. Dispersion additives studied in the media were bovine serum albumin (BSA) as a protein resource, dipalmitoyl phosphatidylcholine (DPPC) as a model lung surfactant, and combination of BSA and DPPC. Dispersions were characterized using optical microscopy and transmission electron microscopy. Our results showed that protein addition, BSA or FCS, in cell culture media generated small agglomerates of primary particles with narrow size variations and improved the stability of the dispersions and thus also the relevance of the in-vitro genotoxicity tests to be done.

The liver is among the most frequently targeted organs by noxious chemicals of diverse nature. Liver toxicity testing using laboratory animals not only raises serious ethical questions, but is also rather poorly predictive of human safety towards chemicals. Increasing attention is, therefore, being paid to the development of non-animal and human-based testing schemes, which rely to a great extent on in vitro methodology. The present paper proposes a rationalized tiered in vitro testing strategy to detect liver toxicity triggered by chemicals, in which the first tier is focused on assessing general cytotoxicity, while the second tier is aimed at identifying liver-specific toxicity as such. A state-of-the-art overview is provided of the most commonly used in vitro assays that can be used in both tiers. Advantages and disadvantages of each assay as well as overall practical considerations are discussed.

In vitro toxicity testing has found widespread application in its use for screening materials for medical devices. Cytotoxicity tests, which have been in use for nearly 20 years, have been validated for intralaboratory repeatability, interlaboratory reproducibility, and correlation with acute animal toxicity assays. The three primary cytotoxicity assays, i.e., direct contact, agar diffusion, and elution tests, allow a selection between assay and material characteristics. Mutagenicity assays have had limited application to materials testing because of the insoluble nature of the materials and the low level of extractable chemicals, which are generally below the sensitivity limit of these assays. In vitro blood compatibility tests for hemolysis and complement activation are used primarily for blood contacting materials in applications where there is a large surface area of material for ex vivo applications.

If “cell toxicology” is defined as the discipline aimed at studying the general principles of chemical interference with cellular structures and/or functions, then “comparative cell toxicology” may be defined as the study of the variety of responses to xenobiotics using: (a) different endpoints within one cell type; (b) cell types from different tissues from one species; and (c) homologous cell types from different species. If the full potential of in vitro models for toxicity testing is to be realised and the scientific basis for hazard assessment improved, then comparative cell toxicological approaches have to be developed further. In the present paper, an approach using different in vitro systems is described. The approach is aimed at the assessment of the basic toxicological characteristics of chemicals.

Abstract The kidney is frequently involved in adverse effects caused by exposure to foreign compounds, including drugs. An early prediction of those effects is crucial for allowing novel, safe drugs entering the market. Yet, in current pharmacotherapy, drug-induced nephrotoxicity accounts for up to 25% of the reported serious adverse effects, of which one-third is attributed to antimicrobials use. Adverse drug effects can be due to direct toxicity, for instance as a result of kidney-specific determinants, or indirectly by, e.g., vascular effects or crystals deposition. Currently used in vitro assays do not adequately predict in vivo observed effects, predominantly due to an inadequate preservation of the organs’ microenvironment in the models applied. The kidney is highly complex, composed of a filter unit and a tubular segment, together containing over 20 different cell types. The tubular epithelium is highly polarized, and the maintenance of this polarity is critical for optimal functioning and response to environmental signals. Cell polarity is dependent on communication between cells, which includes paracrine and autocrine signals, as well as biomechanic and chemotactic processes. These processes all influence kidney cell proliferation, migration, and differentiation. For drug disposition studies, this microenvironment is essential for prediction of toxic responses. This review provides an overview of drug-induced injuries to the kidney, details on relevant and translational biomarkers, and advances in 3D cultures of human renal cells, including organoids and kidney-on-a-chip platforms.

Toxicity Testing in the 21st Century: A Vision and a Strategy (NRC, 2007) presents a bold plan for chemical toxicity testing that replaces whole-animal tests with cell-culture, genetic, other in-vitro techniques, computational methods, and human monitoring. Although the proposed vision is eloquently described, and recent advances in in-vitro and in-silico methods are impressive, it is difficult believe that replacing in-vitro testing is either practical or wise. It is not clear that the toxicity-related events that occur in whole animals can be adequately replicated using the proposed methods. Protecting public health is a serious endeavor that should not be limited by denying animal testing. Toxicologists and regulators are encouraged to read the report, carefully consider its implications, and share their thoughts. The vision is for too important to ignore.

Reproductive toxicity testing systems are used by national and international regulatory agencies. Protocols have not been standardized between agencies or even within certain agencies. Although there have been efforts at standardization, a certain amount of the differences between testing protocols is a reflection of the needs of the particular agency. New developments in in vitro techniques might lead to new test systems, but reproductive function is dependent upon the interaction of various cells and organs that cannot presently be copied in the test tube; this makes whole-animal testing systems a necessity. The present whole-animal models used by the Food and Drug Administration include the 3 segment reproduction studies used for testing drug safety and the multigeneration studies used for food additives. The Environmental Protection Agency has adopted 2 similar versions of a 2-generation study for the Office of Pesticide Programs and the Office of Toxic Substances. The National Toxicology Program, although not a regulatory agency, has taken a prominent role in reproductive toxicity testing, test system development, and test system evaluation. A new testing system, Fertility Assessment by Continuous Breeding (FACB), is currently being studied as a cost-effective and reliable alternative test system. The FACB protocol houses male and female mice as breeding pairs and removes offspring as soon as they are born during the first 14 weeks to allow continuous mating. Each breeding pair normally has up to 5 litters, and the last litter is saved to evaluate the second generation. The efficiency, reliability, and expense of the protocol are being compared to the existing testing systems.

Liverpool John Moores University and FRAME conducted a joint research project, sponsored by Defra, on the status of alternatives to animal testing with regard to the European Union REACH (Registration, Evaluation and Authorisation of Chemicals) system for the safety testing and risk assessment of chemicals. The project covered all the main toxicity endpoints associated with REACH. This paper focuses on the use of alternative (non-animal) methods (both in vitro and in silico) for acute systemic toxicity and toxicokinetic testing. The paper reviews in vitro tests based on basal cytotoxicity and target organ toxicity, along with QSAR models and expert systems available for this endpoint. The use of PBPK modelling for the prediction of ADME properties is also discussed. These tests are then incorporated into a decision-tree style, integrated testing strategy, which also includes the use of refined in vivo acute toxicity tests, as a last resort. The implementation of the strategy is intended to minimise the use of animals in the testing of acute systemic toxicity and toxicokinetics, whilst satisfying the scientific and logistical demands of the EU REACH legislation.

Air pollution consists of highly variable and complex mixtures recognized as major contributors to morbidity and mortality worldwide. The vast number of chemicals, coupled with limitations surrounding epidemiological and animal studies, has necessitated the development of new approach methods (NAMs) to evaluate air pollution toxicity. These alternative approaches include in vitro (cell-based) models, wherein toxicity of test atmospheres can be evaluated with increased efficiency compared to in vivo studies. In vitro exposure systems have recently been developed with the goal of evaluating air pollutant-induced toxicity; though the specific design parameters implemented in these NAMs-based studies remain in flux. This review aims to outline important design parameters to consider when using in vitro methods to evaluate air pollutant toxicity, with the goal of providing increased accuracy, reproducibility, and effectiveness when incorporating in vitro data into human health evaluations. This review is unique in that experimental considerations and lessons learned are provided, as gathered from first-hand experience developing and testing in vitro models coupled to exposure systems. Reviewed design aspects include cell models, cell exposure conditions, exposure chambers, and toxicity endpoints. Strategies are also discussed to incorporate in vitro findings into the context of in vivo toxicity and overall risk assessment.

The human eye is a specialized organ with a complex anatomy and physiology, because it is characterized by different cell types with specific physiological functions. Given the complexity of the eye, ocular tissues are finely organized and orchestrated. In the last few years, many in vitro models have been developed in order to meet the 3Rs principle (Replacement, Reduction and Refinement) for eye toxicity testing. This procedure is highly necessary to ensure that the risks associated with ophthalmic products meet appropriate safety criteria. In vitro preclinical testing is now a well-established practice of significant importance for evaluating the efficacy and safety of cosmetic, pharmaceutical, and nutraceutical products. Along with in vitro testing, also computational procedures, herein described, for evaluating the pharmacological profile of potential ocular drug candidates including their toxicity, are in rapid expansion. In this review, the ocular cell types and functionality are described, providing an overview about the scientific challenge for the development of three-dimensional (3D) in vitro models.

The aim of the present study was to investigate the suitability of bovine spermatozoa cryopreserved in a “defined” medium as an in vitro model for the assessment of the cytotoxic potential of chemicals. The endpoints used for this purpose were motion activity and cellular ATP content. The evaluation of properties of cryopreserved sperm shortly after thawing and at the end of a one-hour incubation period, shows that the cryoprotective medium developed is able to provide suitable cellular material for cytotoxicity tests. Results from experiments employing substances with known modes of action are presented, and suggest that cryopreserved sperm can be used as successfully as native sperm in cytotoxicity tests.

New informatics capabilities and computational and mathematical modelling techniques, used in combination with highly sensitive molecular biology and mechanistic chemistry approaches, are transforming the way in which we assess the safety of chemicals and products. In recent years, good progress has been made in replacing some of the animal tests required for regulatory purposes with methods using cells and tissues in vitro. Nevertheless, big scientific challenges remain in developing relevant non-animal models able to predict the effects of chemicals which are absorbed systemically. The greatest breakthroughs in non-animal approaches for chemical safety assessment will most likely result from continued multi-disciplinary research investment in predictive (integrative and systems) biology. Some of our current research in this area is described in the present article.

To reduce the considerable investments of toxicity testing and protecting animal welfare, a new toxicity testing strategy based on response pathways of human cell lines has been proposed in the United States to evaluate the chemical exposure risks to human health. However, the in vitro high-throughput assays have not yet been fully applied in ecotoxicity testing. This paper proposes a framework for high-efficiency ecotoxicity testing strategies to evaluate the ecological risk of chemicals. It consists of pathway-based toxicity testing, embryo-based toxicity testing, and predictive toxicology and data extrapolation, etc., according to different situations. The results of ecotoxicity testing or data mining are analyzed together with physicochemical properties, environmental fate, and exposure data of chemicals to conduct a comprehensive risk assessment of chemicals. The framework provides valuable points to establish high-efficiency ecotoxicity testing strategies in the 21st century.

Emerging advances in the field of in vitro toxicity testing attempt to meet the need for reliable human-based safety assessment in drug development. Intrahepatic cholangiocyte organoids (ICOs) are described as a donor-derived in vitro model for disease modelling and regenerative medicine. Here, we explored the potential of hepatocyte-like ICOs (HL-ICOs) in in vitro toxicity testing by exploring the expression and activity of genes involved in drug metabolism, a key determinant in drug-induced toxicity, and the exposure of HL-ICOs to well-known hepatotoxicants. The current state of drug metabolism in HL-ICOs showed levels comparable to those of PHHs and HepaRGs for CYP3A4; however, other enzymes, such as CYP2B6 and CYP2D6, were expressed at lower levels. Additionally, EC50 values were determined in HL-ICOs for acetaminophen (24.0–26.8 mM), diclofenac (475.5–>500 µM), perhexiline (9.7–>31.5 µM), troglitazone (23.1–90.8 µM), and valproic acid (>10 mM). Exposure to the hepatotoxicants showed EC50s in HL-ICOs comparable to those in PHHs and HepaRGs; however, for acetaminophen exposure, HL-ICOs were less sensitive. Further elucidation of enzyme and transporter activity in drug metabolism in HL-ICOs and exposure to a more extensive compound set are needed to accurately define the potential of HL-ICOs in in vitro toxicity testing.
