Human Stem Cell Use: iPS Cell
Molecular Imaging for Stem Cell Science and Clinical Application
Stem cells offer tremendous potential to treat previously intractable diseases. The clinical translation of these therapies, however, presents unique challenges. One challenge is the absence of robust methods to monitor cell location and fate after delivery to the body. The delivery and biological distribution of stem cells over time can be much less predictable compared […]
Generation of functional cells and organs from iPSCs
The development of induced pluripotent stem cell (iPSC) technology may be the most important advance in stem cell biology for the future of medicine. This technology allows one to generate a patient’s own pluripotent stem cells (PSCs) from skin or blood cells. iPSCs can then be reprogrammed to multiply and produce high quality mature cells […]
Epithelial progenitors and the stromal niche as therapeutic targets in lung disease
Chronic lung disease is an enormous societal and medical problem in California and the nation as a whole, representing the third most likely cause of death. Treatment costs were $389.2 billion in 2011 and are expected to reach $832.9 billion in 2021 according to the Milken Institute. Chronic lung diseases cover a spectrum of disorders […]
Development of Cellular Therapies for Retinal Disease
The long term goal of our research program is regeneration of the diseased eye. Age-related macular degeneration, diabetic retinopathy, and retinitis pigmentosa are leading causes of blindness for which there are no effective treatments for the majority of cases. Loss of vision is due to progressive degeneration of the photoreceptor cells, or loss of cells […]
In vitro reprogramming of mouse and human somatic cells to an embryonic state
Embryonic stem (ES) cells are remarkable cells in that they can replicate themselves indefinitely and have the potential to turn into all possible cell type of the body under appropriate environmental conditions. These characteristics make ES cells a unique tool to study development in the culture dish and put them at center stage for regenerative […]
Reprogramming of human somatic cells back to pluripotent embryonic stem cells
The ability to dedifferentiate or reverse lineage-committed cells to pluripotent/multipotent cells might overcome many of the obstacles (e.g. cell sources, immunocompatibility and bioethical concerns) associated with using other ES and adult stem cells in clinical applications. With an efficient dedifferentiation process, it is conceivable that healthy, abundant and easily accessible somatic cells could be reprogrammed […]

Curing Hematological Diseases
The primary aim of this project is to develop treatments for incurable diseases of the blood and immune system. X-linked Severe Combined Immunodeficiency (X-SCID) and Fanconi anemia (FA) are two blood diseases where mutations in a single gene results in the disease. XSCID, more commonly known as the “bubble boy” disease, is characterized by a […]
Developmental Candidates for Cell-Based Therapies for Parkinson’s Disease (PD)
Parkinson’s Disease (PD) is a devastating disorder, stealing vitality from vibrant, productive adults & draining our health care dollars. It is also an excellent model for studying other neurodegenerative conditions. We have discovered that human neural stem cells (hNSCs) may exert a significant beneficial impact in the most authentic, representative, & predictive animal model of […]
Maximizing the Safety of Induced Pluripotent Stem Cells as an Infusion Therapy: Limiting the Mutagenic Threat of Retroelement Retrotransposition during iPSC Generation, Expansion and Differentiation
The ability to convert human skin cells to induced pluripotent stem cells (IPSCs) represents a seminal break-through in stem cell biology. This advance effectively circumvents the problem of immune rejection because the patient’s own skin cells can be used to produce iPSCs. This exciting technology could accelerate treatments for a number of presently incurable diseases. […]
