Lulu Xing, PhD student at the Florey Institute of Neuroscience and Mental Health, has had her image shortlisted in the Node stem cell image competition. If successful, her image will grace the cover of the journal Development.
Lulu's image is of an adult mouse hippocampus, the area of the brain where new memories are formed. Astrocytes (green) were observed around the granule cell layer of the dentate gyrus, as indicated by cell nuclei (red). Some astrocytes were derived from neural precursor cell population (blue).
If you like what you see, please visit Node stem cell image competition and vote 5. Mouse hippocampus. You have until 10 April 2013.
In her PhD studies, Lulu is assessing the contribution of stem cells in the brain following injury using an animal model of multiple sclerosis. She is particularly interested in exploring the contribution of two distinct populations of stem cells in the adult brain: neural precursor cells (NPCs) that are responsible for the generation of neurons and glia in the normal adult brain; and oligodendrocyte progenitor cells (OPCs) that are principally responsible for the generation of specialized glia called oligodendrocytes. Although OPCs have known to play an important role in remyelination for some time, recent evidence suggests that NPCs could also contribute to the generation of new oligodendrocytes after CNS damage. Lulu is supervised by Dr Toby Merson and Prof Trevor Kilpatrick. Lulu is supported by a Stem Cells Australia Strategic Australian Postgraduate Award.
