Human Stem Cell Use: iPS Cell
Development of small molecule screens for autism using patient-derived iPS cells
Autism Spectrum Disorders (ASDs) are a heritable group of neuro-developmental disorders characterized by language impairments, difficulties in social integrations, and the presence of stereotyped and repetitive behaviors. There are no treatments for ASDs, and very few targets for drug development. Recent evidence suggests that some types of ASDs are caused by defects in calcium signaling […]
Development of a Hydrogel Matrix for Stem Cell Growth and Neural Repair after Stroke
Stroke is the leading cause of adult disability. Most patients survive their initial stroke, but do not recover fully. Because of incomplete recovery, up to 1/3 of stroke patients are taken from independence to a nursing home or assisted living environment, and most are left with some disability in strength or control of the arms […]
Site-specific integration of Lmx1a, FoxA2, & Otx2 to optimize dopaminergic differentiation
The objective of this study is to develop a new, optimized technology to obtain a homogenous population of midbrain dopaminergic (mDA) neurons in a culture dish through neuronal differentiation. Dopaminergic neurons of the midbrain are the main source of dopamine in the mammalian central nervous system. Their loss is associated with one of the most […]
Development and Application of Versatile, Automated, Microfluidic Cell Culture System
Supported in part by a previous CIRM Tools and Technologies Grant [REDACTED], we have optimized and scaled up highly advanced (microfluidic) cell culture chips into manufacturable form, produced prototype instruments to drive these chips, and demonstrated that we can culture cells, dose them with combinations of reagents, and export them back off the chip. Since […]
Pluripotent and Somatic Stem Cell Models to Study Inherited Diarrheal Disorders
Our research group at [REDACTED] has had a long-standing interest in understanding the cause of several disorders that result in severe, and often times fatal forms of diarrhea in children. These diarrheal disorders are inherited, and somehow lead to poor absorption of nearly all forms of nutrients, including protein, sugars and fats. Why children with […]
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 […]
Developing a therapeutic candidate for Canavan disease using induced pluripotent stem cell
Canavan disease is a devastating disease of infants which affects their neural development and leads to mental retardation and early death. It occurs in 1 in 6,400 persons in the U.S. and there is no treatment so far. We propose to generate genetically-repaired and patient-specific stem cells (called iPSCs) from patients’ skin cells, and then […]
Crosstalk: Inflammation in Parkinson’s disease (PD) in a humanized in vitro model
Parkinson’s Disease (PD) is the most common neurodegenerative movement disorder. It is characterized by motor impairment such as slowness of movements, shaking and gait disturbances. Age is the most consistent risk factor for PD, and as we have an aging population, it is of upmost importance that we find therapies to limit the social, economic […]
New Drug Discovery for SMA using Patient-derived Induced Pluripotent Stem Cells
Spinal muscular atrophy (SMA) is the leading genetic cause of infant death in the U.S. This devastating disease affects 1 child in every 6,000-10,000 live births, with a North American prevalence of approximately 14,000 individuals. The disease is characterized by the death of spinal cord cells called motor neurons that connect the brain to muscle. […]
Developing a drug-screening system for Autism Spectrum Disorders using human neurons
Autism and autism spectrum disorders (ASD) are complex neurodevelopmental diseases that affect 1 in 150 children in the United States. Such diseases are mainly characterized by deficits in verbal communication, impaired social interaction, and limited and repetitive interests and behavior. Because autism is a complex spectrum of disorders, a different combination of genetic mutations is […]
