Organ-on-a-chip (OoC) technologies are promising tools to reduce the reliance on animal models in basic and applied research.
On this page
Organ-on-a-chip (OoC) technologies, also known as microphysiological systems (MPS) or tissue chips, are microfluidic cell culture devices that recapitulate the structure, function and (patho)physiology of human tissues and organs in vitro.
We support the development and uptake of OoC technology through a variety of mechanisms including:
- Funding research and innovation.
- Collaborating nationally and internationally.
- Disseminating opportunities through our events and webinars.
Below you can find out more about our OoC activities as well as other global programmes and initiatives. The aim of these resources is to showcase our portfolio of projects in this area and provide information and support for the community, including technology developers, end-users, regulators and in vivo researchers who are looking to adopt alternative approaches.
Reports and recommendations
This NC3Rs report, published in 2021, summarises the current OoC landscape and our recommendations for supporting the technology's development and wider adoption.
Summary from a joint OoC workshop, held in 2018, outlining the key focus areas for the UK to advance the technology.
MPSCoRe working group
We have established with NICEATM (the US National Toxicology Program Interagency Center for the Evaluation of Alternative Toxicological Methods) a working group to coordinate global efforts for the use of microphysiological systems (organ-on-a-chip and other complex multicellular in vitro models) to reduce reliance on in vivo studies of COVID-19.
Learn more about the MPSCoRe working group in Our portfolio.
We fund the development and application of OoC technology across our research funding and CRACK IT innovation programmes, and encourage applications in this space. To date we have committed £10.2M funding, which has led to the development of OoC models for assessing kidney and CNS toxicities and ovarian cancer research. Below, you can find out more about the OoC research we have funded.
Our Skills and Knowledge Transfer grants support the adoption of established 3Rs technologies through funding collaborations between model developers and end-users.
Our CRACK IT programme champions innovation in the 3Rs, turning great ideas into products and services.
- If you are an end-user, you may be interested in submitting an idea for a CRACK IT Challenge through our annual open call (e.g. a call for a new product or technology targeted to your needs). Visit the Sponsor a Challenge page on our Innovation Platform website to find out more.
- If you are a technology developer looking to identify new partners and customers to further develop, validate and use your OoC technology then you may be interested in showcasing your technology through the technology partnering platform konfer. Please visit the Technology Partnering page on the Innovation Platform website for further information.

Global programmes and initiatives
Funding and partnerships have been critical in supporting OoC development and moving it towards commercialisation and adoption. The non-exhaustive list below summarises some of the past and on-going global programmes and initiatives in the OoC field.
Led by the National Centre for Advancing Translational Sciences, part of the National Institute of Health, this programme was launched in 2012 with the aim to develop tissue chips of human organ systems to better predict drug safety and efficacy. A range of diverse platforms have been developed and two Tissue Chip Testing Centres and a Tissue Chip Database Centre have been established to independently test and validate these platforms. The programme continues to grow focusing on efficacy and disease modelling, personalised medicine, the immune system and tissue chips in space.
Papers describing the programme and outputs:
The programme was launched in 2012 with the aim to develop an in vitro platform linking ten or more organ systems together to evaluate the safety and efficacy of novel medical countermeasures (e.g. emerging infectious diseases and chemical or biological attack). Funding was awarded to teams from the Massachusetts Institute of Technology (MIT) and the Wyss Institute, which led to the development of two platforms. The DARPA report summarises the programme and its outputs.
Papers describing the platforms developed:
A not-for-profit organisation of pharmaceutical and biotechnology companies to facilitate cross-pharma collaboration and data sharing of microphysiological systems (MPS), raising awareness of and supporting MPS qualification and implementation.
A series of papers was published in Lab on a Chip outlining the pharmaceutical industry perspectives and considerations for developing, evaluating and characterisating MPS models to support drug discovery and development – see Fabre et al. (2020).
The NA3RsC has established the MPS initiative to encourage collaborations to increase adoption and regulatory acceptance of the technology. The initiative includes representatives from providers of commercial systems and end-users.
The German GO-Bio multi-organ bioreactor programme
A GO-Bio grant was awarded to the Technisch Universitat Berlin in collaboration with TissUse GmbH and the Fraunhofer IWS in Dresden and the Fraunhofer IGB in Stuttgart.
Papers describing the multi-organ models developed including a human 3D liver and skin model and an ADME chip connecting human intestine, skin, liver and kidney:
Funding was awarded to a consortium including InSphero AG (Switzerland), ETH Zurich (Switzerland)), KU Leuven (Belgium), Technical University Dortmund (Germany) and AstraZeneca to develop a device that interconnects multi-organ tissue models. This led to the generation of a plate-base device commercialised by InSphero as the AkuraTM Flow.
Initiated in 2015, hDMT is a pre-competitive, not-for-profit technological R&D institute integrating human stem cell technologies with academic and industry expertise to develop human organ and disease models-on-a-chip. Focus areas include vessels-on-chip/vascular disease, heart-on-chip/cardiac diseases, cancer-on-chip and brain-on-chip.
A Horizon 2020 funded EU initiative started in 2017 with the aim of creating an OoC roadmap and building a network of academic, research, industrial and regulatory institutions to move the technologies from the laboratory towards adoption.
The project has finished and the roadmap has been published, outlined in Mastrangeli et al. (2019). The roadmap will continue to be implemented through the European Organ-on-Chip Society established in 2018 as one of the outputs from ORCHID. The Society, a not-for-profit organisation, provides opportunities to share knowledge and expertise in the field, and runs an annual conference.
The Centre for Alternatives to Animal Testing (CAAT)/CAAT Europe T4 Think Tank on MPS
In 2015, a CAAT Transatlantic Think Tank of Toxicology (t4) workshop, brought together global stakeholders to discuss the status of OoC technologies for industry needs and requirements to facilitate adoption and regulatory acceptance. In 2019, a subsequent workshop was held to discuss the barriers that need to be overcome for the technology to be adopted by the pharmaceutical industry and to achieve regulatory acceptance.

- Summary of the recommendations from the 2019 workshop highlighting where the technology has started to be implemented in the pharmaceutical industry and a road map to adoption and regulatory acceptance: Marx et al. (2020)
A network funded by the MRC, EPSRC and BBSRC to capture, inspire and grow the UK research activity in the OoC field.
The project aims to develop OoCs populated with cells derived from induced pluripotent stem cells that can be applied for safety and pharmacokinetics in drug discovery, with a focus on liver, intestine, kidney and the blood-brain barrier.
