The Alzheimer’s Research UK Stem Cell Research Centre

In 2012, Prof John Gurdon and Prof Shinya Yamanaka won the Nobel Prize for Medicine. Their pioneering work developed a technique to turn adult cells, such as those from the gut, into stem cells.  The next big challenge has been to use these stem cells to answer key medical questions, one of which being how nerve cells are damaged in Alzheimer’s disease. Today sees the launch of the Alzheimer’s Research UK Stem Cell Research Centre, a collaboration between the University of Cambridge and University College London, kindly supported by The Alborada Trust. The use of stem cells in research can be a controversial issue and there are common misconceptions about the methods used. In this blog, I will explain the use of stem cells in dementia research and how the Stem Cell Research Centre can bring us closer to finding treatments for dementia.

What are stem cells?

During development in the womb, an embryo is made up of a collection of stem cells. These stem cells can become any type of cell in the body, depending on the triggers they receive. For example, nerve cells, heart cells and bone cells can all be formed from the same original stem cell. As the embryo continues to develop, cells undergo a process called differentiation. This means that they become more specialised and can no longer become any cell in the body.

How do we get the stem cells?

As adults, we are fully developed and therefore no longer have many stem cells, only in specific parts of the body, like bone marrow and the gut. So scientists have to ‘make’ stem cells, using the groundbreaking methods that won Prof Gurdon and Yamanaka the Nobel Prize.

Biology is in a lot of ways like cooking.  Scientists follow ‘recipes’ to turn starting ingredients into something useful. Researchers at the Alzheimer’s Research UK Stem Cell Research Centre will take skin cells donated by people with Alzheimer’s and follow a ‘nerve cell recipe’. This will involve treating the skin cells so that they become less specialised and more like stem cells. Instead of only being able to become skin cells, these newly formed stem cells can be triggered to become nerve cells. Not bad for what started as a swab of skin cells!

Not only do these new nerve cells grow well in the lab, they behave in a similar way as they would in the brain, communicating together in networks. This is particularly important when studying Alzheimer’s as a lot of the symptoms of the disease are caused by damage to nerve cell communication.

Why are stem cells useful in dementia research?

Researchers do not intend to implant these new nerve cells into the brains of people with Alzheimer’s, to repair the damage caused by the disease. Instead, scientists want to study how these nerve cells behave. Scientists can study, in a dish, the initial stages of the disease, hunting for clues about how nerve cell damage begins and how it can be halted.

These cells will also help researchers to unravel the genetic risk factors for Alzheimer’s. It is known that some versions of genes mean that people have a higher chance of developing Alzheimer’s. However, we do not yet know why these genetic differences lead to the disease. By creating nerve cells from patients with these genetic risk factors, researchers hope to understand their role in causing Alzheimer’s.

The potential of stem cells isn’t only in understanding Alzheimer’s. Excitingly, these nerve cells can also be used to test potential treatments. Lots of different drugs can be tested on nerve cells to see whether the damage from Alzheimer’s can be stopped. This is not a substitute for testing drugs in clinical trials, but scientists hope that this technology will provide a way to see whether potential treatments might work, in experiments that are relevant to people with Alzheimer’s.

Stem cell research has many possibilities and we need initiatives like the Alzheimer’s Research UK Stem Cell Research Centre to bring together experts to work towards a common goal. We believe that funding this world-class research will bring us one step closer to our aim to defeat dementia.

    How can I sign up for tests?

    Read Andrew White’s “Faith Under Fire” (2012). Andrew White, the vicar of Bagdhad, originally qualified as a medical doctor before theology. Parish in Coventry, World Council of Churches in Geneva, then Bagdhad. He suffers from MS and was deteriorating fast, not least due to his punishing schedule. One of his projects was to fund raise to purchase essential equipment for St George’s Hospital in Bagdad. While visiting the facility, one of his professor-doctor friends suggested that they experiment with the process – on some of the equipment that he had helped fund raise – to filter blood from his arm to capture stem cells, and then to inject the concentrate in his neck. It made an immediate difference and although it needs re-doing every three months, it has changed his life, certyainly, ramped him back up a couple of enrgy-notches. I am a chartered engineer rather than a medical doctor, but if there is stem cell research for Alzheimer, could this source of auto-produced stem cells – from the patient – not be an opportunity. According to the book, the procedure is also done in Lebanon. Is it dome in the wes? Has it been tested on Alzheimer or other forms of dementia? My wife was diagnosed with Early Onset Alzheimer when she was 52, and she is now 57. We live in South West London and attend St George’s, Tooting. Any chance of being a guinee pig?

    Dear Sirs,

    I would appreciate if you have information on Alzheimer Institutes in Florida state – nearby (Miami surrounding area) that would take care of patients with Alzheimer – I would be grateful if you can help me

    if you can send me a list of Alzheimer Institutes that takes care in their own dependency of patients with this disease – thanks so much
