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 […]
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 […]
Autologous Retinal Pigmented Epithelial Cells Derived from Induced Pluripotent Stem Cells for the Treatment of Atrophic Age Related Macular Degeneration
The leading cause of visual loss in Americans over the age of 65 is age related macular degeneration (AMD) which occurs in both a “wet” and a “dry” form. Both forms of the disease are associated with loss of cells called retinal pigmented epithelium (RPE) which can lead to profound loss of central vision. Currently, […]
Stem Cell-Based Therapy for Cartilage Regeneration and Osteoarthritis
Arthritis is the result of degeneration of cartilage (the tissue lining the joints) and leads to pain and limitation of function. Arthritis and other rheumatic diseases are among the most common of all health conditions and are the number one cause of disability in the United States. The annual economic impact of arthritis in the […]
Neural Stem Cells as a Developmental Candidate to Treat Alzheimer Disease
Alzheimer disease (AD), the most common cause of dementia among the elderly and the third leading cause of death, presently afflicts over 5 million people in the USA, including over 500,000 in California. Age is the major risk factor, with 5% of the population over age 65 affected, with the incidence doubling every 5 years […]
Regulation of Stem Cell Fate in Bioengineered Arrays of Hydrogel Microwells
Stem cell biology, since its inception 30 years ago, has been hindered by our limited ability to observe and direct the decisions of individual stem cells. In the case of adult tissue-specific stem cells, such as those from blood, muscle or pancreas, the numbers available for clinical use are extremely limited, as in tissue culture […]
Using Human Embryonic Stem Cells to Understand and to Develop New Therapies for Alzheimer’s Disease
Alzheimer’s Disease (AD) is a progressive incurable disease that robs people of their memory and ability to think and reason. It is emotionally, and sometimes financially devastating to families that must cope when a parent or spouse develops AD. Unfortunately, however, we currently lack an understanding of Alzheimer’s Disease (AD) that is sufficient to drive […]
Therapeutic potential of Retinal Pigment Epithelial cell lines derived from hES cells for retinal degeneration.
Retinal degeneration represents a group of blinding diseases that are increasingly impacting the health and well being of Californians. It is estimated that by 2020, over 450,000 Californians will suffer from vision loss or blindness due to the age-related macular degeneration (AMD), the most common cause of retinal degeneration diseases in the elderly. Furthermore, retinitis […]
Generation of forebrain neurons from human embryonic stem cells
The goal of this proposal is to generate forebrain neurons from human embryonic stem cells. Our general strategy is to sequentially expose ES cells to signals that lead to differentiation along a neuronal lineage, and to select for cells that display characteristics of forebrain neurons. These cells would then be used in transplantation experiments to […]
Utilizing Age-Specific Adipocyte Progenitor Cells for Cell Therapy in Older Patients
Research Objective A new type of APC serves older patients as 1) better MSC in immunomodulation (reducing inflammation) for autologous transplantation; 2) better source of somatic cells for generating heathier hiPSCs. Impact Bottlenecks: 1) Older patients suffer from sarcopenic obesity, which has no safe and effective treatment. 2) Cell therapy in older patients is often […]
