ES-Derived Cells for the Treatment of Alzheimer’s Disease
Alzheimer’s disease is the most common cause of dementia in the elderly, affecting over 5 million people in the US alone. Boosting immune responses to beta-Amyloid (Aβ) has proven beneficial in mouse models and Alzheimer’s disease (AD) patients. Vaccinating Alzheimer’s mice with Aβ improves cognitive performance and lessens pathological features within the brain, such as […]

Combinatorial Chemistry Approaches to Develop LIgands against Leukemia Stem Cells
Various cells and organs in the human body originate from a small group of primitive cells called stem cells. Human cancer cells were also recently found to arise from a group of special stem cells, called cancer stem cells (CSCs). At present, cancer that has spread throughout the body (metastasized) is difficult to treat, and […]
Mechanisms of Hematopoietic stem cell Specification and Self-Renewal
During an individual’s lifetime, blood-forming cells in the bone marrow called hematopoietic stem cells (HSCs) supply all the red and white blood cells needed to sustain life. These blood stem cells are unique because they can make an identical copy of themselves (self-renew). Disorders of the blood system can be terminal, but such diseases may […]
Skeletal muscle development from hESC and its in vivo applications in animal models of muscular dystrophy
Embryonic stem cells (ESC) originating from early stage embryos are able to differentiate into any type of cells in the body. The generation of ESC lines from human embryos (hESC) has attracted a lot of dispute among researchers, but raised the hope that one day hESCs can be used in cell replacement therapy for the […]
Generating pluripotent cell lines from neurons.
Stem cell research holds great promise for neurological disease. One in three Americans will suffer from diseases of the nervous system ranging from stroke to Alzheimer’s disease to epilepsy. Very few treatments for neurological disease exist, in part because of he lack of suitable in vitro models with which to test therapeutics. In addition, many […]
Genetic Encoding Novel Amino Acids in Embryonic Stem Cells for Molecular Understanding of Differentiation to Dopamine Neurons
Embryonic stem cells have the capacity to self-renew and differentiate into other cell types. Understanding how this is regulated on the molecular level would enable us to manipulate the process and guide stem cells to generate specific types of cells for safe transplantation. However, complex networks of intracellular cofactors and external signals from the environment […]
Molecular mechanisms involved in adult neural stem cell maintenance
The adult brain contains a pool of stem cells, termed adult neural stem cells, that could be used for regenerative purposes in diseases that affect the nervous system. The goal of this proposal is to understand the mechanisms that promote the maintenance of adult neural stem cells as an organism ages. Understanding the factors that […]
Enhancing Survival of Embryonic Stem Cell-Derived Grafts by Induction of Immunological Tolerance
Although ESC-based therapies hold great promise for the cure of a wide diversity of degenerative diseases, rapid progress to actual human clinical trials is hindered by the lack of preclinical data for specific ESC-based therapies. I aim to move the process forward by establishing a protocol in which immune system cells are reproducibly produced from […]
A Novel Engineered Niche to Explore the Vasculogenic Potential of Embryonic Stem Cells
Cardiovascular diseases account for an estimated $330 billion in health care costs each year, afflict 61.8 million Americans, and will account for more than 1.5 million deaths in the U.S. this year alone. A number of these diseases are characterized by either insufficient blood vessel growth or damage to the existing vessels, resulting in inadequate […]
