Stage of Program: Candidate Discovery (DISC2, some 1.0 projects)
Prospective isolation of hESC-derived hematopoietic and cardiomyocyte stem cells
The capacity of human embryonic stem cells (hESCs) to perpetuate themselves indefinitely in culture and to differentiate to all cell types of the body has lead to numerous studies that aim to isolate therapeutically relevant cells for the benefit of patients, and also to study how genetic diseases develop. However, hESCs can cause tumors called […]
hESC-Derived Motor Neurons For the Treatment of Cervical Spinal Cord Injury
Cervical spinal cord injuries result in a loss of upper limb function because the cells within the spinal cord that control upper limb muscles are destroyed. The goal of this research program is to create a renewable human source of these cells, to restore upper limb function in both acute and chronic spinal cord injuries. […]
Human Embryonic Stem Cell Therapeutic Strategies to Target HIV Disease
AIDS is a disease that currently has no cure. It arises when the human immunodeficiency virus (HIV) infects certain types of blood cells. These cells would normally be used to fight infection, but instead are destroyed by the virus, leading to immunodeficiency. We have recently been able to induce the development of human embryonic stem […]
MEF2C-Directed Neurogenesis From Human Embryonic Stem Cells
Understanding differentiation of human embryonic stem cells (hESCs) provides insight into early human development and will help directing hESC differentiation for future cell-based therapies of Parkinson’s disease, stroke and other neurodegenerative conditions. The PI’s laboratory was the first to clone and characterize the transcription factor MEF2C, a protein that can direct the orchestra of genes […]
Regulated Expansion of Lympho-hematopoietic Stem and Progenitor Cells from Human Embryonic Stem Cells (hESC)
The clinical potential of human embryonic stem cells (hESC) for transplantation will be realized only when we can develop methods to control the process of tissue differentiation far more efficiently than is currently the case. From over 40 years of experience with adult stem cells, it is recognized that the growth of transplanted bone marrow […]

Human stem cell derived oligodendrocytes for treatment of stroke and MS
Strokes that affect the nerves cells, i.e., “gray matter”, consistently receive the most attention. However, the kind of strokes that affecting the “wiring” of the brain, i.e., “white matter”, cause nearly as much disability. The most severe disability is caused when the stroke is in the wiring (axons) that connect the brain and spinal cord; […]
Spinal ischemic paraplegia: modulation by human embryonic stem cell implant.
schemia-induced paraplegia often combined with a qualitatively defined increase in muscle tone (i.e. spasticity and rigidity) is a serious complication associated with a temporary aortic cross-clamping ( a surgical procedure to repair an aortic aneurysm). In addition to spinal ischemic injury-induced spasticity and rigidity a significant population of patients with traumatic spinal injury develop a […]
Derivation of Inhibitory Nerve Cells from Human Embryonic Stem Cells
Parkinson’s disease (PD) is caused by degeneration of a specific population of dopamine-producing nerve cells in the brain and is chronic, progressive, and incurable. Loss of dopamine-containing cells results in profound physiological disturbances producing tremors, rigidity, and severe deterioration of gate and balance. In the United States, approximately 1.5 million people suffer with PD and […]
Immunology of neural stem cell fate and function
One of the most difficult yet ultimately rewarding goals in stem cell research is to repair damaged neural systems with newly generated neurons. Our work examining neuronal integration and survival in the postnatal and adult brain shows that incoming neurons are uniquely and exquisitely sensitive to the immune response and inflammation that is always present […]
