Scientists create living model of basic units of human brain

Researchers in the School of Life & Health Sciences at Aston University in Birmingham, UK are developing a novel new way to model how the human brain works by creating a living representation of the brain.

They are using cells originally from a tumour which have been ‘reprogrammed’ to stop multiplying. Using the same natural molecule the body does to stimulate cellular development, the cells are turned into a co-culture of nerve cells and astrocytes - the most basic units of the human brain.

These co-cultures can be developed into tiny, connected balls of cells called neurospheres, which can process information, which, at a very simple level, is the basis of thought. The research process does not require animal testing and since 2007 has been generously supported by the Humane Research Trust.

In the future, the tiny three-dimensional cell clusters, which are essentially very small models of the human nervous system, could be used to develop new treatments for diseases including Alzheimer’s, Motor Neurone and Parkinson’s Disease. These progressive and debilitating neurodegenerative conditions are becoming more common as the population of the UK ages.

Professor Michael Coleman, who is leading the research team, said: ‘We are aiming to be able to study the human brain at the most basic level, using an actual living human cellular system. Cells have to be alive and operating efficiently to enable us to really understand how the brain works. In the longer term we hope that our procedure can be used to help us understand how conditions such as Alzheimer’s and other neurodegenerative diseases develop. At the moment, most people are only too aware that current treatments for these conditions do not halt their progress and often have side-effects. We hope that our technique will provide scientists with a new and highly relevant human experimental model to help us understand the brain better and develop new drugs and treatments to tackle neurodegenerative disease ’

Researchers at Aston University in Birmingham took cells from a cancerous tumour and "reprogrammed" them to create those identical to the human nervous system.

Scientists say that the development could mean that a breakthough in conditions such as dementia and Parkinson's Disease has been brought closer

Researchers have developed an artificial bit of human brain to help them study Alzheimer's and other diseases, a huge improvement over animal models.Mike Coleman and his team from Aston University, Birmingham, have developed artificial brain tissue that responds to some chemicals like human brains do. Their findings were presented at the British Festival of Science in Birmingham.  ...

The British Science Festival  is one of Europe's largest science festivals, taking place each September. Each year the Festival travels to a different UK location, bringing you the latest in science, technology and engineering.

This year's Festival was held in Birmingham from 14-19 September. Many events will took place at Aston University campus and at various venues across Birmingham.
