Hematopoietic Transplants From Autologous Pluripotent Cell Sources

Summary
This proposal investigates the utility of two types of patient-derived stem cells for transplantation into blood. These are induced pluripotent stem cells that are reprogrammed from specialized tissues such as skin cells, and stem cells derived using the genetic material of oocytes or sperm only ( one-parent embryos). Using the mouse, we are looking at the ability of these cells to form normal blood lineages after transplantation, and to repair blood in a mouse model for beta-thalassemia.
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.
A Suite Of Engineered Human Pluripotent Stem Cell Lines To Facilitate The Generation Of Hematopoietic Stem Cells

Summary
Our goal is to develop tools that address major bottlenecks that have prevented the generation of blood forming stem cells in culture for therapeutic use. We will generate human embryonic stem cell reporter lines that can be used to monitor key milestones in blood stem cell development. These lines will serve as tools to identify growth conditions to improve the differentiation of pluripotent stem cells to functional blood stem cells.
Generation Of Embryonic Stem Cell-like Cells By Reprogramming Somatic Cell Nuclei

Summary
Human embryonic stem (ES) cells possess considerable potential in treating numerous human diseases. However, ethical concerns surround the isolation of embryonic stem cells from human embryos. Therefore, this proposal aims to develop a reliable method of deriving human ES-like cells from normal adult cells (eg. skin cells). For example, preliminary results suggest ES cells can impart their 'stemness' onto adult cells when the two cells are fused together.

Summary
Cartilage is frequently damaged, but does not repair on its own, and degenerates in osteoarthritis. Unfortunately, current treatments are also not able to regenerate the structure of normal cartilage and fail to restore joint function long-term. Our project, HydroZONES, brings together expertise from 16 partners to tackle this problem and regenerate cartilage with the appropriate structure to help the millions of people worldwide suffering from cartilage problems such as osteoarthritis.

Blood stem cells are long-lived and can give rise to every cell type of the blood system and due to these properties they are currently used in the clinics. Despite their importance, our knowledge of the mechanisms the control the multiplication of these rare cells is very scarce.

Leveraging Genomics Strategies To Generate Adult Neurons From IPSCs And Somatic Cells

Funding Amount
$1,593,336.00
Summary
Recent advances have made it possible to derive myriad specialized human cells from stem cells or by directly reprogramming cell identity. However, these derived cells are generally arrested at a fetal developmental stage, and do not mature to function like adult cells. We will use new genomic, epigenetic, cell reprogramming, and manipulation methods to discover how to derive mature cells, aiming to generate mature neurons for use in neurobiology research, disease modeling, and drug screening.
Characterisation Of Human Embryonic Stem Cell Differentiation To Haematopoietic Progenitors And Stem Cells

Funding Amount
$638,856.00
Summary
Blood stem cells, which are found in the bone marrow, are currently used for treating human blood disorders including leukemia and lymphoma. However, for the majority of bone marrow transplant candidates, suitable donors cannot be found. Using embryonic stem cells, this project aims to define the conditions required to generate blood stem cells in the laboratory. The aim of the work is to provide a new source of blood stem cells that could be used in place of donor derived bone marrow.
