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…
Purified allogeneic hematopoietic stem cells as a platform for tolerance induction
Blood and immune cells originate and mature in the bone marrow. Bone marrow cells are mixtures of blood cells at different stages of development, and include rare populations of blood-forming…
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…
Generation of disease models for neurodegenerative disorders in hESCs by gene targeting
The ability to target a specific locus in the mouse genome and to alter it in a specific fashion has fundamentally changed experimental design and made mice the preeminent model…
Discovery of adhesion ligands for pluripotent human stem cells
We have assembled a team of investigators with complementary expertise in applying the state-of-the-art “one-bead-one-compound” (OBOC) combinatorial library methods to identify synthetic chemical molecules that bind to unique receptors (protein…
Development of the Theracyte Cellular Encapsulation System for Delivery of human ES Cell-derived Pancreatic Islets and Progenitors.
There are several challenges to the successful implementation of a cellular therapy for insulin dependent diabetes derived from Human Embryonic Stem Cells (hESCs). Among these are the development of functional…
Novel Separation of Stem Cell Subpopulations
The inability to separate stem cells and their differentiated progeny accurately, easily, and rapidly undermines progress in the stem cell field. Traditional separation of living cells into subpopulations relies on…
Magnetic Particle Imaging: A Novel Ultra-sensitive Imaging Scanner for Tracking Stem Cells In Vivo
We aim to develop, test and validate a new, sensitive and affordable scanner for tracking the location of injected cells in humans and animals. This new scanning method, called Magnetic…
Development of Baculoviral Vectors for Gene Editing of Human Stem Cells
Stem cells are powerful undifferentiated cells that are able to both regenerate themselves and differentiate into different mature cell types, such as lung cells or liver cells. The ability to…
