Stem cell models of disease

Project areas

Research focus


Pluripotent stem cell derived neurons expressing green fluorescent protein (under the control of LMX1A promoters) and counter labelled with antibodies to a non-specific neuronal marker (β3 tubulin, in white) and a marker of nuclei (blue). These cells were isolated using green fluorescence activated cell sort 15 days before immunolabeling. While many remain green, it is clear that some are not. We are currently investigating how neurons respond to their extracellular environment in health and disease.

Stem cells can self-renew indefinitely and, being pluripotent, they can develop into any cell type present in the adult. Much of the focus of stem cell biology is directed at the specification of particular cellular phenotypes (neurons, cardiomyocytes, blood, etc.) for use in cell replacement therapies, drug screening and disease modelling.

My research is largely focussed on the development of models of neuropsychiatric and neurodegenerative diseases. The first step in this model development program is defining conditions that permit the generation of specific cell types (for example, A9 or A10 midbrain dopaminergic neurons), the second step is defining conditions that reflect the environment associated with disease. This simple approach enables us to track the progression of healthy cells to unhealthy states. Understanding disease pathology enables us to efficiently direct studies toward new therapeutic targets.

The Stem Cell Group at MIPS has generated a number of embryonic stem cell reporter lines enabling the identification of particular neurons in culture. The development of these reporter lines underlies our core interest in developing human stem cell based models of human disease; however, these fluorescent reporter lines have a broader significance and we have used them to facilitate (i) the identification of conditions conducive to the enrichment of specific neural phenotypes, (ii) the characterization of neurons in culture and (iii) the development of models of neurodegeneration and neuropsychiatric disease.
