Fighting cancer at the Animal Replacement Centre

By Uncategorised


The Animal Replacement Centre of Excellence (ARC) , funded by a £1 million investment by Animal Free Research UK, aims to maximise and build upon a long-standing successful partnership with the Blizard Institute, a pioneer in the development of in vitro human research models.

The ARC uses cutting-edge science to advance human models for human disease and aims to reduce the number of animals currently used in cancer research by providing a unique environment for scientists to work together with the common goal to develop, validate and apply human-based models of disease. It also aims to inspire the next generation of scientists through education about animal free research and further funding opportunities. Professor Mike Philpott and Dr Adrian Biddle drive the cutting-edge research.

Humane human skin cancer model

Professor Philpott’s research focusses on growing human cells to replicate real human cell tissue. He does this by taking unwanted human skin left over from cosmetic surgery and growing the cells in three dimensions. To investigate skin cancer, these cells can then be manipulated by expressing proteins and genes that cause tumours to develop.

Instead of comparing grown human skin cancer models to induced cancer in mice to see if they behave the same way, they are compared to real human cancer skin samples from hospital patients. This cuts out the need for mice completely.

Targeting problem-causing tumour cells

Some tumours shrink after successful treatment, but then grow back again. Dr. Adrian Biddle’s research aims to answer why some of these tumour stem cells survive initial cancer treatments and then go on to form secondary tumours away from the initial growth site. Most researchers use mice models to study the complex mechanisms of tumour cells travelling through the body. Yet Dr. Biddle argues that

[tumour spread] needs to be investigated in a controlled environment where you can look at every step – you can’t do that in an animal.

He is therefore developing a more pertinent way to model this process using human cells in a dish, with a goal to identify and target the problem-causing tumour stem cells.

Professor Philpot and Dr. Biddle approximate that thousands of mice are experimented on every year in modelling skin cancer, tens of thousands in developing general human skin models and hundreds of thousands in general cancer stem cell research. Dr. Biddle explains that,

tumour research in mice is achieved by either putting a human tumour into a mouse or changing the genes of the mouse to induce a mouse tumour.

Professor Philpot is suspicious that many of these mice models used are not a good representation of cancer in humans. The team at the Animal Replacement Centre are therefore making a big impact by showing that it is possible to replace the use of many thousands of mice through developing lab-grown and more human-relevant tumour models.

The team has already successfully made human models of basel cell carcinoma (the most common skin cancer). When they tried to treat their human model with some of the standard drugs currently used on patients, they found that the drugs did not reverse some of the cancer genes that should have been switched back to normal.

A lot of patients also do not respond to the treatments, which indicates that there are many other cell changes caused by the cancer that are not being treated by the drugs that have been tested on mice. Therefore it is important to develop these drugs using a human model to ensure that the other pathways involved in the cancer are not missed during development and the best possible treatments can be found.
