Human Stem Cell Use: Adult or Tissue Stem Cell
ZINC FINGER NUCLEASE-BASED STEM CELL THERAPY FOR AIDS
Some years ago it was discovered that patients homozygous for a natural mutation (the Δ32 mutation) in the CCR5 gene are generally resistant to HIV infection by blocking virus entry to a cell. Building on this observation, a study published in 2009 reported a potential “cure” in an AIDS patient with leukemia after receiving a […]
Human Cardiovascular Progenitors, their Niches and Control of Self-renewal and Cell Fate
For the millions of Americans who are born with or develop heart disease, stem cell research offers the first hope of reversing or repairing heart muscle damage. Thus, early reports suggesting heart regeneration after transplantation of adult bone marrow-derived stem cells were met with great excitement in both the scientific and lay community. However, although […]
Stem Cell-based Disease Modeling Shared Resource Laboratory
Our Shared Resource Laboratory will expand access to stem cell-derived models to support research and educational programs with two main goals: democratize access to state-of-the-art models and technology among a diverse scientific community and catalyze innovation in regenerative medicine. This Shared Resource Laboratory will expand access to stem cell-derived models to regions of Southern California […]
Interrogating Satellite Cell and Myofiber Defects and Repair in Human DMD using Single Nuclei/Single Cell RNA Sequencing of Muscle Resident Cells
Research Objective We will describe, for the first time, human muscle satellite cell, myofiber and immune cell dynamics due to dystrophin deficiency and AAV gene therapy in human muscle at single nuclei resolution. Impact These studies will elucidate satellite stem cell and myofiber defects in Duchenne and Becker Muscular Dystrophy and determine efficacy, mechanism and […]
Harnessing the rejuvenating capacity of pregnancy-associated factors to restore aged stem cell function
Research Objective Elucidation of pregnancy-related factors that mitigate cellular senescence and enhance regeneration has far-reaching implications for understanding the mechanisms of aging and rejuvenation. Impact The study will address the long-standing knowledge gaps related to the mechanisms of pro-regenerative impact of pregnant milieu and female muscle stem cell senescence Major Proposed Activities Isolation of female […]
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 […]
Ex vivo fate mapping of human lung stem cell plasticity in fibrotic disease
Research Objective This proposal will design new models to study behavior that is specific to human lung stem cells, and screen for drugs that can target abnormal stem cells in fibrotic disease. Impact This study will generate potential new therapeutic approaches to fibrotic lung diseases such as idiopathic pulmonary fibrosis. Major Proposed Activities Development of […]
Overcoming barriers for airway stem cell gene therapy for Cystic Fibrosis
Research Objective This research will allow the targeting of airway stem cells for long lived gene therapy for Cystic Fibrosis and for other airway diseases Impact We will overcome the barriers to accessing airway basal stem cells for gene correction for Cystic Fibrosis (CF) and use a new gene correction strategy to correct >99% of […]
Identifying roadblocks to neural stem cell transplantation into human tissues.
Research Objective We will generate a comprehensive map of human neural stem cell differentiation profiles that will serve as a reference for enhancing neural stem cell-based therapies.
