BULLETIN 79 WINTER 2014
A win for Menzies and for stem cell science We are very proud to be celebrating with Dr Kaylene Young, a Menzies neuroscientist who is one of two Australians to be awarded the inaugural Metcalf Prize. Dr Young and Dr Jose Polo, who is from the Australian Regenerative Medicine Institute at Monash University, will each receive $50,000 to further their research. The prize honours the pioneering stem cell work by Professor Donald Metcalf, who is still working in the field and who will mentor the two winners over the next year.
Dr Young and her colleagues at Menzies have found that neural stem and related progenitor cells reside within the outer region of the brain called the cortex, which is a brain region prone to damage. By understanding the behaviour and function of these cells, they one day hope to use them to treat nervous and brain disorders or damage.
Dr Young’s expertise is in the potential for stem cells in the brain to repair brain injuries and even treat diseases such as multiple sclerosis and Alzheimer’s. Dr Graeme Blackman, OAM, the Chairman of the National Stem Cell Foundation said “We were stunned by the quality of the applications. Our inaugural winners, Kaylene Young and Jose Polo, stood out from a remarkable field of young research leaders. We can expect great things from Australian stem cell research in the next few years.”
‘Bad’ fats culprit in MS progression Menzies’ researchers have found adverse levels of ‘bad’ fats in the blood are closely linked to the level of disability in people with multiple sclerosis (MS) and the rate of disability progression.

Fats are an essential component of the brain and contribute to its repair and maintenance. This particular study examined the fat profiles from blood samples of 141 people with relapsing remitting MS. The samples were collected at six monthly intervals over two and a half years as part of the NHMRC-funded Tasmanian MS Longitudinal Study.
The significant findings were published in the Multiple Sclerosis Journal and suggest dietary and lifestyle modifications that improve fat profiles in the blood may also slow the rate of disability progression in MS.
The results showed the amounts of a number of different fats in the blood, including total cholesterol, were closely associated with disability level, and the association remained strong even when other potentially confounding factors such as smoking, exercise, age and sex were taken into account. Fat levels did not have any influence on the risk of experiencing a relapse for the people in the study and body mass index was also not related to relapses.
The lead researcher on the study, Dr Ingrid van der Mei, said the finding was very significant for the 23,000 Australians living with MS.
This research was funded by MS Research Australia (via a project grant in 2012).
