Summary
Several recent breakthroughs have made us realise that there is a lot of plasticity in cellular development, and we can now harness this plasticity to create stem cells that may eventually be used to repair the damaged heart and blood vessels after heart attacks and stroke. Here we will use mouse stem cells to discover the genetic factors responsible for a cell’s plasticity and memory in order to create pure populations of heart and blood vessel cells that can be used in repair settings.
Role Of Epigenomic Changes In Conferring Hyperglycemic Memory

Summary
The major burden of type I diabetes remains its vascular complications including diabetes-accelerated athersclerosis. Despite improved glucose control, diabetic individuals develop complications as a result of prior poor glycemic control. Although the development and progression of these diabetic complications is strongly associated with mean levels of glucose, recent studies suggest that the deleterious effects of early exposure to high levels of glucose persist for years even after treatment h ....The major burden of type I diabetes remains its vascular complications including diabetes-accelerated athersclerosis. Despite improved glucose control, diabetic individuals develop complications as a result of prior poor glycemic control. Although the development and progression of these diabetic complications is strongly associated with mean levels of glucose, recent studies suggest that the deleterious effects of early exposure to high levels of glucose persist for years even after treatment has returned glucose levels towards normal.Read moreRead less
Deciphering The Metabolic And Endocrine Profile Of Healthy Adipocytes

$563,194.00
Summary
Obesity is associated with the development of metabolic diseases, however, it is becoming clear that it is where the excess fat is stored that is more important when predicting the health risks associated with obesity. This project aims to identify whether adipocyte progenitor cells, which eventually become fat cells, are ‘preprogrammed’ and whether differences in these cells explain the generation of either healthy or unhealthy fat in different locations of the body.
A Study Of The Origins Of Macrophages In Healthy And Atherosclerotic Vasculature Focusing On A Novel Population Of Resident Adventitial Macrophage Progenitor Cells (AMPCs)

Funding Amount
$465,345.00
Summary
White blood cells (macrophages) play a key role in the development of atherosclerosis, the underlying cause of most heart attacks and strokes. We have made new discoveries to show that there are stem (progenitor) cells for macrophages that exist within the outer lining of blood vessels. This project will study whether these local progenitor cells, called AMPCs, are a source of macrophages in atherosclerosis and in turn could lead to new treatment approaches for cardiovascular disease.
Targeting Renal And Vascular Inflammation In Hypertension

Funding Amount
$781,589.00
Summary
Inflammation is a hallmark of high blood pressure (A.K.A. hypertension) and underlies clinical complications of the condition such as kidney failure and blood vessel disease. This project will investigate whether a recently described signaling complex termed the 'inflammasome' is a trigger of inflammation in hypertension in the hope of identifying it as a target for new drugs that are more effective in the treatment of hypertension and its complications.
A Critical New Signaling Axis In Lymphatic Vascular Angiogenesis

Summary
The lymphatic vasculature is a crucial part of our vascular system required for tissue fluid drainage and maintenance of fluid homeostasis. Lymphatic vessels play major roles in vascular pathologies and in the spread of solid tumours during cancer progression. We have discovered a new molecular regulator controlling the formation of lymphatic vessels. This project will determine the signalling pathway employed by this new regulator and potential for future therapeutic applications.
Bioengineering Synthetic Elastin Conduits For Arterial Revascularisation

Funding Amount
$624,776.00
Summary
An arterial substitute with both physical and biological properties that mimic those of the human vasculature has long been the holy grail of vascular tissue engineering. We propose synthetic elastin can form the basis of a durable, clinically effective small diameter vascular graft and fill a significant unmet need for a biocompatible vascular substitute.
Coupling The Mechanical, Signalling And Transcriptional Mechanisms That Initiate Pathogenesis Of Cerebral Cavernous Malformation
Funder

Funding Amount
$1,228,364.00
Summary
Cerebral cavernous malformations (CCMs) are thin walled, vascular malformations in the brain found in 1/200-250 individuals. They can cause migraine, neurological deficits or stroke. This disease can be inherited due to damaging mutations in any of three CCM genes. The project will investigate the molecular control of CCM pathogenesis in animal models. We aim to uncover the molecular cause of these vascular malformations and in doing so identify new therapeutic strategies.
Comparison Of Periodontal Ligament Stem Cells And Induced Pluripotent Periodontal Ligament Stem Cells For Periodontal Regeneration

Funding Amount
$831,955.00
Summary
In the first part of this study we will determine whether induced pluripotent stem cells or adult stem cells from the periodontal ligament are better candidates for periodontal regeneration. Secondly, using CAD/CAM technology we will make tissue engineering scaffolds tailored to fit periodontal defects and seeded with stem cells to improve on current techniques used to regenerate damaged tissues around teeth affected by periodontal disease.

Summary
The stem cells in the outer protective layers of the epithelium of the skin (keratinocyte stem cells), possess an intrinsically high capability to regenerate tissue. However, this tissue regenerative ability can be enhanced by interactions with microenvironmental elements i.e. connective tissue cells and proteins.
