Human Stem Cell Use: Adult or Tissue Stem Cell
Tissue engineered cartilage from autologous, dermis-isolated, adult, stem (DIAS) cells
This study addresses the cartilage defects resulting from injuries or from wear-and-tear that can eventually degenerate to osteoarthritis. This is a significant problem that impacts millions and costs in excess of $65B per annum in the US alone. Addressing this indication successfully holds potential for halting the progression of cartilage damage before it destroys the […]
Targeting Stem Cells to Enhance Remyelination in the Treatment of Multiple Sclerosis
Multiple sclerosis (MS) is an autoimmune disease in which the myelin sheath that insulates neurons is destroyed, resulting in loss of proper neuronal function. Existing treatments for MS are based on strategies that suppress the immune response. While these drugs do provide benefit by reducing relapses and delaying progression (but have significant side effects), the […]
USP16 controls stem cell number: implications for Down Syndrome
Stem cells are endowed with the ability to self-renew, that means to give rise to other cells with the same potential to regenerate a tissue. Recently, we found a gene that also regulates this mechanism. In addition, expression of high levels of this gene can reduce the number of stem cells in the bone marrow […]
Tri-resolution Visualization System for Stem Cells and Tissue Regeneration Monitoring
The 3D imaging techniques of CT and MRI have virtually eliminated the need for exploratory surgery – a procedure which was common in difficult cases just 20-30 years ago. Not only is imaging used to discover the extent of disease, it is now used to measure the effect of therapies. The “size” of a tumor […]
Development of Single Cell MRI Technology using Genetically-Encoded Iron-Based Reporters
Clinical application of cell transplantation therapy requires a means of non-invasively monitoring these cells in the patient. Several imaging modalities, including MRI, bioluminescence imaging, and positron emission tomography have been used to track stem cells in vivo. For MR imaging, cells are pre-loaded with molecules or particles that substantially alter the image brightness; the most […]
Preparation and Delivery of Clinically Relevant Numbers of Stem Cells Using 3D Hydrogels
A critical bottleneck to translate the promise of regenerative medicine to the clinic is the ability to efficiently harvest, expand, and deliver sufficient numbers of viable stem cells. While relatively large numbers of patient-specific, multipotent human adipocyte stem cells (hASC) can be harvested from adults, these cells must be re-delivered to the patient (either with […]
Regeneration of Functional Human Corneal Epithelial Progenitor Cells
Over 3.2 million people worldwide are bilateral blind from corneal diseases. Limbal stem cell deficiency (LSCD) has been recognized as a major cause, either primary or secondary, of significant visual loss and blindness in many common corneal disorders. A healthy, transparent ocular surface is made up of non-keratinized, stratified squamous epithelium that is highly differentiated. […]

Systemic Adult Stem Cell Therapy for Osteoporosis-Related Vertebral Compression Fractures
Vertebral compression fractures are the most common fractures associated with osteoporosis. Approximately 700,000 osteoporosis-related vertebral compression fractures (OVCFs) occur each year in the US. Currently, treatment is focused primarily on prevention. When fractures occur in patients with osteoporosis, treatment options are limited because open surgery with implants often fails. Recently, new therapies involving injection of […]
Development of RNA-based approaches to stem cell gene therapy for HIV
Despite significant advances in treatment and prevention programs, HIV infection with progression to Acquired Immunodeficiency Syndrome (AIDS) is still prevalent in California. The CDC Estimates >56,000 new cases of HIV infection each year in the US with over 148,000 cumulative cases reported in California alone (as of 2009). Multi-drug therapy has been helpful in reducing […]
