Summary
Transfusion of fresh red blood cell units of the correct blood type into patients can be life saving. However, access to units of the correct blood type is often limited due to limited supply of donor blood and its short shelf life creating the need for a constant donor blood supply. We propose to develop a system that allows us to generate unlimited numbers of human red blood cells in a culture dish which we will derive from differentiating human embryonic stem cell lines.
Bone Marrow Endothelial Stem Cells Have The Capacity To Form Both The Endothelial And Haemopoietic Hierarchies

Summary
Blood cell formation is hierarchically organised; with hemopoietic stem cells (HSC) responsible for producing mature circulating blood cells. HSC reside in marrow near blood vessel cells. Although these play a key role in HSC regulation their origin in adults is poorly understood. We have demonstrated the existence of adult marrow vessel stem cells at the apex of a parallel hierarchy. Our objective is to characterise these in mice and humans and determine their role in blood malignancies.
Endocytosis And Asymmetric Cell Division In Leukemia.

Summary
Self-renewal allows normal haematopoeitic stem cells to constantly replenish the blood system. Conversely, leukemia stem cells use self-renewal to propagate the disease, and utilise the quiescence phase to evade treatment eradication. We identified that the endocytic gene, Ap2a2 enhances haematopoeitic stem cell self-renewal. Through Ap2a2, we are now investigating the role of endocytosis and self-renewal in leukemia and ex vivo expansion of human haematopoietic stem cells.
Characterization Of HOXA-expressing Human Haematopoietic Cells Generated From Embryonic Stem Cells

Summary
Blood stem cell transplants are used for treating a range of human blood disorders such as leukaemias. However, for many patients, suitable donors cannot be found. We are searching for ways in which embryonic stem cells can be turned into blood stem cells in the laboratory to provide a new source of these cells that could then be used to treat patients.

Summary
T-cell acute lymphoblastic leukaemia (T-ALL) results from the abnormal development of T cells that are an important cell type in the body's immune system. Although the prognosis for T-ALL has improved remarkably over the last decade, for one out of five T-ALL cases the underlying genetic defects remain unresolved and are refractory to current therapies. This project aims to use both novel mouse models and human patient cell lines to better understand this disease and discover novel targets for f ....T-cell acute lymphoblastic leukaemia (T-ALL) results from the abnormal development of T cells that are an important cell type in the body's immune system.
