Summary
Osteoporosis affects 1.2 million Australians and will cost $33.6 billion by 2022. This study aims to develop a novel nano-cement platform for custom-designed bone repair in osteoporosis, by using purpose-designed nanomaterials and advanced 3D printing technique. The research findings will lead to the development of a new bone repair strategy, expand knowledge on both biomaterials engineering and osteoporosis treatment, and improve the quality of life of Australians.

Summary
Fetal stem cells cross into the mother during pregnancy and persist lifelong in her tissues. To determine whether helpful or harmful, we will study how these cells contribute to healing both after acute injury and in chronic genetic models like brittle-bone disease and muscular dystrophy. This research will inform long-term consequences of pregnancy, important for women's health and longevity, and help develop a promising form of stem cell therapy.
Understanding the differentiation of the endocardium. The project aims to understand the genetic regulation of endocardial development. The heart is essential for survival, its beat the indicator of life. The endocardium, the heart’s inner lining, is required for signalling during heart development and is a major component of the valves, septa and trabeculae. Despite its indispensable role, little is known about how it forms or develops. This project integrates two complementary approaches that ....Understanding the differentiation of the endocardium. The project aims to understand the genetic regulation of endocardial development. The heart is essential for survival, its beat the indicator of life. The endocardium, the heart’s inner lining, is required for signalling during heart development and is a major component of the valves, septa and trabeculae. Despite its indispensable role, little is known about how it forms or develops. This project integrates two complementary approaches that have identified the earliest marker of endocardial differentiation and devised the method to make endocardium from stem cells. Knowledge from this work will inform future research into growing and regenerating damaged tissue.Read moreRead less
Kruppel-like factors and the methylome. This project aims to test the hypothesis that the KLF/SP family of transcription factors work in part via dynamic interactions with methylated cytosine nucleotides in DNA. This is fundamental to their function as pioneer factors in reprograming and their ability to co-ordinate differentiation and organogenesis. Conversely, dynamic changes in methylation status engage or disengage new regulatory elements in the genome via recruitment of KLF/SP family protei ....Kruppel-like factors and the methylome. This project aims to test the hypothesis that the KLF/SP family of transcription factors work in part via dynamic interactions with methylated cytosine nucleotides in DNA. This is fundamental to their function as pioneer factors in reprograming and their ability to co-ordinate differentiation and organogenesis. Conversely, dynamic changes in methylation status engage or disengage new regulatory elements in the genome via recruitment of KLF/SP family proteins as specific effectors. This project will address a new paradigm in genetics that is likely to underpin development.Read moreRead less
Hypoxia-mimicking bio-scaffold for skeleton regeneration. The project is to develop bioactive bone grafts to improve bone repair and shorten the recovery time of patients with fractures, degenerative joint diseases, and bone cancer and bone deformities.
The development of new scaffolds for bone repair comprising polycaprolactone and strontium-substituted bioactive glasses. The drive to develop bone grafts to fill major gaps in the skeleton, whilst circumventing the need to use permanent implants has led to a major research thrust towards developing biomaterials for bone-tissue engineering. The project will develop scaffolds with highly osteoconductive bioactive glasses in a polymer matrix for bone regeneration applications.
Smart Matrix™ approaches towards neo vascularisation in bone repair. Bone injuries cost Australia more than $1 billion annually. The development of a medical device combining novel pro-angiogenic technology, Smart Matrix™, with polymer scaffolds for treatment of bone defects by this project, will facilitate rapid development of a blood supply within the defect, aiding bone growth and reducing overall costs compared to current treatments.
Elucidating surface-mediated permissive cues for cellular differentiation. This project will develop a novel biomaterial platform technology that will enable firstly the probing and thereafter the control of the cellular pathways of adult mesenchymal stem cells. These fundamental insights will be translated into novel stem cell culture ware products that will enable clinically relevant, functional tissue repair and regeneration.
Controlling the adhesome to regulate cell fate on biomaterials. Mesenchymal stem cell-based tissue engineering practices are hampered worldwide by the lack of appreciation and understanding of the matrix-mediated cues that must be provided during adhesion and spreading to drive cells to definitive tissue end points. This project will address these knowledge deficiencies by combining high throughput array technologies, a set of tailorable self-assembling biomaterials and real-time biosensors to r ....Controlling the adhesome to regulate cell fate on biomaterials. Mesenchymal stem cell-based tissue engineering practices are hampered worldwide by the lack of appreciation and understanding of the matrix-mediated cues that must be provided during adhesion and spreading to drive cells to definitive tissue end points. This project will address these knowledge deficiencies by combining high throughput array technologies, a set of tailorable self-assembling biomaterials and real-time biosensors to rapidly, at high resolution, elucidate how mechanotransductive cues determine the fate choice of mesenchymal stem cells, and furthermore, how to manipulate them with smart biomaterial design to achieve desired outcomes for tissue engineering.

Potency and activity of Meso-Endothelial bipotent progenitors in vivo. This project aims to characterise a new stem cell population that can maintain both blood vessels and contribute to a variety of tissues whether fibrous, bone, fat or cartilage. Blood vessels comprise an inner endothelial layer and surrounding mesenchyme, are integral to many organs and constitute a unique system connecting different parts of the body. Despite their importance little is known about how they are maintained and ....Potency and activity of Meso-Endothelial bipotent progenitors in vivo. This project aims to characterise a new stem cell population that can maintain both blood vessels and contribute to a variety of tissues whether fibrous, bone, fat or cartilage. Blood vessels comprise an inner endothelial layer and surrounding mesenchyme, are integral to many organs and constitute a unique system connecting different parts of the body. Despite their importance little is known about how they are maintained and how they contribute to the response to injury. Previous work has described several populations of stem cell capable of self renewal and repletion of the endothelium or the mesenchyme. This project will examine the potency of these different progenitors to give rise to each of these fates in homeostasis but also during sounding and bone formation. This will help define a unique population of stem cells capable of both vascular and mesenchymal repair.Read moreRead less
