Technologies to improve in vivo function of transplanted stem cells
Stem cell-based therapy is recognized as a promising therapeutic approach for treating various diseases that are currently intractable. One strategy in regenerative medicine is to transplant stem cells or their differentiated derivatives to regenerate the damaged tissues or halt tissue degeneration. Human embryonic stem cells and human induced pluripotent stem cells having the potential to […]
Molecular regulation of stem cell potency
The field of stem cell biology as it applies to regenerative medicine requires a detailed understanding of what controls stem cell function. Our fundamental interest is in the molecular pathways that control how potent as a stem is in terms of its ability to make new tissues in response to injury and disease. We have […]
Combination therapy to Enhance Antisense Mediated Exon Skipping for Duchenne Muscular Dystrophy
Duchenne muscular dystrophy (DMD) affects 1 in every 3,500 boys worldwide. DMD is caused by mutations in the gene encoding dystrophin, a protein key to muscle health. DMD patients are typically weaker than normal by age 3, and with progressive muscle weakness most loose the ability to walk by age 11. DMD progresses to complete […]
Engineered iPSC for therapy of limb girdle muscular dystrophy type 2B
Limb girdle muscular dystrophy type 2B (LGMD 2B) is a form of muscular dystrophy that leads to muscle degeneration and disability. In LGMD 2B, a vital muscle protein is mutated, and its absence leads to progressive degeneration of muscles in the body that are needed for mobility. To create a therapy, we will provide a […]
Characterization of Human Skeletal Muscle Stem Cells for Clinical Application
Skeletal muscle makes up 40% of our bodies, dictates our form, is responsible for our ability to move, express ourselves, eat, breath and to look around. Restoration or preservation of the body’s normal form and function is the central goal of regenerative medicine and the central focus of my clinical specialty of plastic and reconstructive […]
Combination Therapy to Enhance Antisense Mediated Exon Skipping for Duchenne Muscular Dystrophy
Duchenne muscular dystrophy (DMD) is the most common muscular dystrophy and one of the most common fatal genetic disorders. Approximately one in every 3,500 boys worldwide is affected with DMD. Extrapolating from population based studies, there are over 15,000 people currently living with DMD in the US. DMD is a devastating and incurable muscle-wasting disease […]
Local Delivery of Rejuvenated Old Muscle Stem Cells to Increase Strength in Aged Patients
As humans age, the ability to regenerate skeletal muscle tissue is impaired. Injuries to the musculoskeletal system that require extended periods of immobilization lead to muscle atrophy and are particularly devastating to the elderly population. Loss of skeletal muscle mass and function reduces mobility, which negatively affects quality of life, and increases the risk of […]
Combination therapy to Enhance Antisense Mediated Exon Skipping for Duchenne Muscular Dystrophy
A drug was identified through the use of muscle stem cells that can enhance the effectiveness of exon skipping by antisense oligonucleotides to the DMD gene to restore dystrophin expression and at least partially correct the defect responsible for loss of muscle function in Duchenne. We propose to test the effectiveness of this drug in […]
Phenotypic Analysis of Human ES Cell-Derived Muscle Stem Cells
We study human muscle development, and are actively investigating potential cell-based therapies for the treatment of degenerative muscle diseases, such as muscle dystrophy. This project will define the pathway that muscle stem cells follow as they form new muscle, and identify which muscle stem cells are most useful for therapy. Our approach will be to […]
Stem Cell Therapy for Duchenne Muscular Dystrophy
Duchenne muscular dystrophy (DMD) is the most common and serious form of muscular dystrophy. One out of every 3500 boys is born with the disorder, and it is invariably fatal. Until recently, there was little hope that the widespread muscle degeneration that accompanies this disease could be combated. However, stem cell therapy now offers that […]
