Human Stem Cell Use: iPS Cell
White matter neuroregeneration after chemotherapy: stem cell therapy for “chemobrain”
Chemotherapy for cancer is often life saving, but it also causes a debilitating syndrome of impaired cognition characterized by deficits in attention, concentration, information processing speed, multitasking and memory. As a result, many cancer survivors find themselves unable to return to work or function in their lives as they had before their cancer therapy. These […]
Human endothelial reprogramming for hematopoietic stem cell therapy.
The current roadblocks to hematopoietic stem cell (HSC) therapies include the rarity of matched donors for bone marrow transplant, engraftment failures, common shortages of donated blood, and the inability to expand HSCs ex vivo in large numbers. These major obstacles would cease to exist if an extensive, bankable, inexhaustible, and patient-matched supply of blood were […]
Human Induced Pluripotent Stem Cell-Derived Cardiovascular Progenitor Cells for Cardiac Cell Therapy.
Despite therapeutic advances, cardiovascular disease remains a leading cause of mortality and morbidity in California. Regenerative therapies that restore normal function after a heart attack would have an enormous societal and financial impact. Although very promising, regenerative cardiac cell therapy faces a number of challenges and technological hurdles. Human induced pluripotent stem cells (hiPSC) allow […]
Human pluripotent stem cell-based therapeutics for preeclampsia
Preeclampsia (PE) is a pregnancy complication, characterized by high blood pressure and abnormal kidney function, which affects 5-8% of all pregnancies. It is responsible for a significant proportion of maternal deaths and growth-restricted babies; it is also a major reason why obstetricians induce delivery prematurely, resulting in additional neonatal complications, often requiring extended stays in […]
Epigenetic regulation of human cardiac differentiation
Each cell type in our body has its own identity. This identity allows a heart cell to contract repetitively, and a brain cell to conduct nerve impulses. Each cell type gains its identity by turning on or off thousands of genes that together give the cell its identity. Understanding how these sets of genes are […]
3D Modeling of Retina using Polymer Scaffolds for Understanding Disease Pathogenesis
Inherited retinal degenerations result in visual loss in patients as early as in their adolescence. Retinitis Pigmentosa includes a group of such degenerations which run in families and can result in legal blindness by 40 years of age. Even though we know by now a number of gene mutations which can cause these disorders, we […]
Investigation of the role of O-GlcNAcylation in SOX2 function during reprogramming
Induced pluripotent stem cells (iPSCs) are a potential source of material for cell replacement therapies. Thus, achieving maximal efficiency of reprogramming will be important for cellular medicine. In this submission we propose to test whether manipulating the mammalian glucose sensing pathway. The enzyme OGT is part of the glucose-sensing pathway and is necessary in pluripotent […]
Induction of Pluripotent Stem Cell-Derived Pacemaking Cells
Currently, over 350,000 patients per year with abnormal heart rhythm receive electronic pacemakers to restore their normal heart beat. Electronic pacemakers do not respond to the need for changing heart rate in situations such as exercise and have limited battery life, which can be resolved with biopacemakers. In this proposed project, we will examine methods […]
Studying Arrhythmogenic Right Ventricular Dysplasia with patient-specific iPS cells
Most heart conditions leading to sudden death or impaired pumping heart functions in the young people (
Transcriptional regulation of pluripotency in human embryonic stem cells
All of the diverse cells in the human body contain the same genetic information, and originally arose from a single cell, a fertilized egg. Embryogenesis is a result of cell division followed by differential gene expression, to selectively activate only the genes needed for development of each specialized cell type. By understanding the multiple gene […]
