Developing An In Vitro Model Of A Human Blastocyst

Funding Amount
$890,062.00
Summary
Using novel cellular and molecular technologies we propose to develop an artificial model of an early human blastocyst. This will allow us to study the first initial steps in human development without the use of real embryos. Such a model will not only help us decipher the first steps in human development, but we anticipate it will be essential to study how gene mutations and the environment affect this initial step in human development.
Generation Of Human Intestinal Stem Cells By Direct Reprogramming

Summary
Intestinal stem cells (ISCs) can give rise to mini guts in vitro with exciting applications for drug screening and cell based regenerative medicine. However, currently the establishment of mini gut cultures requires an invasive procedure. By taking advantage of a revolutionary new predictive algorithm (Mogrify) we will generate ISC directly from somatic and pluripotent cell sources.
Pre-Clinical Studies Towards Cell-Based Approaches For Cortical Repair.

Summary
This project seeks to determine whether brain cells that die after stroke can be functionally replaced using cells grown in the laboratory from human stem cells. Current therapies for stroke aim to limit the damage but do not allow for actual recovery of brain function. By growing turning stem cells into specialised cells that match the ones lost after stroke, this project aims to restore motor function by transplanting these cells into the injured brain.
Understanding The Pathogenesis Of Mitochondrial Disease Using IPS Cells

Summary
Induced pluripotent stem (iPS) cells are stem cells derived from adult skin cells that can be converted into cell types such as neurons. iPS cells offer great promise in understanding and treating inherited disorders. However, there are concerns that the “epigenetic memory” of iPS cells has not been completely erased, which may limit the utility of iPS cells. We will evaluate and validate the use of iPS technology in mouse and human models of inherited disorders affecting energy generation.
This proposal seeks to determine the therapeutic potential of stem cells for the treatment of brain injury early in life, for example as occurs in cerebral palsy. The project will test the capacity of implanted stem cells to both protect the brain and also to functionally replace cells lost to the injury in order to improve motor and cognitive function.
Epigenetic Reprogramming Within The Pluripotent Lineage Of The Early Embryo

Summary
Cells of the early embryo have the remarkable capacity to form all of the different tissues and organs in the body. This property requires re-organisation of the embryo’s genetic material in a manner analogous to re-booting a computer. This project will define the properties of this rebooting process. This information will allow much better strategies for building spare parts for regenerative medicine and provide the information required to reduce the incidence of inborn defects.
Pre-clinical Steps Towards A Stem Cell Therapy For Parkinson's Disease.

Funding Amount
$1,179,594.00
Summary
A promising experimental therapy for Parkinson's disease is the use of stem cells that in order to replace the cells lost during the disease process. A challenge for this approach is that upon transplantation into the brain, in addition to the therapeutic cell types, there will also be unwanted cell types such as those that can form tumours. This proposal seeks to establish a novel strategy for removing those cells prior to transplantation.
Identifying Genes That Function As Epigenetic Barriers To Cell Reprogramming

Funding Amount
$379,649.00
Summary
Stem cells can form many different cell types and show significant promise in cell therapies. New technologies allow the generation of stem cells from adult cell types such as skin cells, but these technologies are inefficient and typically introduce new genetic material to the cells. This project will develop new, more efficient approaches for producing stem cells potentially without the introduction of genetic material, thereby improving the use of these stem cells in therapies.
This research program aims to unveil for the first time the black box that the reprogramming of human cells into pluripotency is. This is important from a basic biology point of view as it allows for the understanding of the forces that control cell fate and also, from a therapeutic point of view, for the full development of new reprogramming strategies using these two stages of pluripotency. Thus, the outcomes of this grant will facilitate clinical translation of future stem cell iPS cells base
Molecular And Functional Characterisation Of Induced Multipotent Stem Cells

Funding Amount
$694,428.00
Summary
We have developed a new method to convert fat and other cell types into stem cells that can repair damaged tissues. We call these cells, induced multipotent stem cells or iMS cells. In this project we will identify the molecular changes that occur in a mature cell as it converts into a stem cell and the extent to which iMS contribute to different tissue types. These investigations will lay the foundation for human clinical trials using iMS cells.
