Organ-on-a-chip for assessing environmental toxicants

Area of Science:

• Environmental Toxicology
• Biomedical Engineering
• Human Physiology Simulation

Background:

• Man-made xenobiotics contaminate the environment, posing unknown risks to ecosystems and human health.
• Conventional toxicological screening models (animal, in vitro) have limitations in predicting human responses due to inter-species differences and lack of physiological relevance.
• There is a critical need for advanced screening methods to assess environmental toxicants and their impact.

Purpose of the Study:

• To highlight the potential of organ-on-a-chip (OOC) technology for environmental toxicology.
• To demonstrate how OOC systems can provide human physiology-relevant models for toxicant screening.
• To explore the development of interconnected multi-organ-on-chip systems for comprehensive toxicological studies.

Main Methods:

• Utilizing organ-on-a-chip systems to recapitulate in vivo-like human organ environments.
• Developing interconnected networks of multiple organs-on-chip to create a 'human-on-a-chip' model.
• Investigating the metabolism, collective response, and fate of toxicants within these advanced models.

Main Results:

• Organ-on-a-chip systems can realistically mimic human organ environments and responses.
• Interconnected OOC networks enable dynamic study of toxicant journeys and effects within the human body.
• This technology shows potential for high predictive power in environmental toxicology.

Conclusions:

• Organ-on-a-chip technology presents a significant advancement over traditional methods for environmental toxicant screening.
• The development of human-on-a-chip systems offers a more accurate and predictive platform for assessing chemical risks.
• Further advancements in OOC technology are expected to enhance its utility in safeguarding human and environmental health.
