Thymus based tolerance to stem cell therapies
This proposal focuses on the role of the immune system in transplantation of derivatives of human pluripotent stem cells (hPSCs). A critical roadblock to successful cell replacement therapies, no matter…
Stem cell tolerance through the use of engineered antigen-specific regulatory T cells
Type 1 Diabetes (T1D) occurs as a consequence of uncontrolled immune activation, culminating in the destruction of insulin-producing beta-cells. Efforts to prevent or reverse diabetes have been limited by the…
Stem cell differentiation to thymic epithelium for inducing tolerance to stem cells
The thymus is an organ that plays a key role in controlling immune responses and immune tolerance. The thymus promotes immune tolerance by deleting and removing self-reactive T cells from…
Defining the Isoform-Specific Effects of Apolipoprotein E on the Development of iPS Cells into Functional Neurons in Vitro and in Vivo
GOALS We propose to determine the effects of different forms of apoE on the development of induced pluripotent stem (iPS) cells into functional neurons. In Aim 1, iPS cells will…
Mechanisms Underlying the Responses of Normal and Cancer Stem Cells to Environmental and Therapeutic Insults
Adult stem cells play an essential role in the maintenance of tissue homeostasis. Environmental and therapeutic insults leading to DNA damage dramatically impact stem cell functions and can lead to…
Building Cardiac Tissue from Stem Cells and Natural Matrices
Congestive heart failure afflicts 4.8 million people, with 400,000 new cases each year. Myocardial infarction (MI), also known as a "heart attack", leads to a loss of cardiac tissue and…
Mechanisms in Choroid Plexus Epithelial Development
Buried deep inside the brain are cells known as choroid plexus epithelial (CPe) cells. Although not as famous as other cells in the nervous system, CPe cells perform a large…
The roles of non-coding RNAs in the self-renewal and differentiation of pluripotent stem cells
There are thousands of cell types in the animal body, many of which can be derived from embryonic stem cells (ES cells), a pluripotent cell type that thrive in cell…
Mechanisms of small RNA regulation in early embryonic development
The promise of embryonic stem cells in regenerative medicine is based on their potential to make every cell in the body, a property coined pluripotency. With rapid recent advances in…
Stem Cells for Immune System Regeneration to Fight Cancer
This proposal will define the biology of stem cell engineering to produce a cancer-fighting immune system. The immune system protects our body against most outside threats. However, it frequently fails…
