Human Stem Cell Use: Embryonic Stem Cell
Engineering microscale tissue constructs from human pluripotent stem cells
Tissues derived from stem cells can serve multiple purposes to enhance biomedical therapies. Human tissues engineered from stem cells hold tremendous potential to serve as better substrates for the discovery and development of new drugs, accurately model development or disease progression, and one day ultimately be used directly to repair, restore and replace traumatically injured […]
Single Molecule Biophysics and Biology of Cellular Identity
One of your earliest childhood biology lessons probably occurred when your body demonstrated to you that your skin is an organ that is able to self-regenerate. Indeed wound healing is a fascinating process in which cells carry out a precise and complex choreography that includes cellular differentiation and regulation of gene expression. Our lab studies […]
Molecular Imaging for Stem Cell Science and Clinical Application
Stem cells offer tremendous potential to treat previously intractable diseases. The clinical translation of these therapies, however, presents unique challenges. One challenge is the absence of robust methods to monitor cell location and fate after delivery to the body. The delivery and biological distribution of stem cells over time can be much less predictable compared […]
Repair and regeneration of the nephron
Kidney function is essential for removing the wastes that result from normal cell function and maintaining water and salt balance in our internal tissues. These actions are carried out by roughly a million nephrons within the kidney that filter all the body’s blood roughly once every 1-2hours. The kidney also regulates other tissues controlling blood […]
Development of Cellular Therapies for Retinal Disease
The long term goal of our research program is regeneration of the diseased eye. Age-related macular degeneration, diabetic retinopathy, and retinitis pigmentosa are leading causes of blindness for which there are no effective treatments for the majority of cases. Loss of vision is due to progressive degeneration of the photoreceptor cells, or loss of cells […]
Characterization of mechanisms regulating de-differentiation and the re-acquisition of stem cell identity
Stem cells are the building blocks during development of organisms as varied as plants and humans. In addition, adult or “tissue” stem cells provide for the maintenance and regeneration of tissues, such as blood and skin throughout the lifetime of an individual. The ability of stem cells to contribute to these processes depends on their […]

Epigenetics in cancer stem cell initiation and clinical outcome prediction
Cancer is responsible for approximately 25% of all deaths in the US and other developed countries. For women, breast and lung cancers and for men, cancers of prostate and lung are the most prevalent and the most common cause of deaths from cancer. While a large number of treatment modalities such as surgery, chemotherapy, radiation […]
Transcriptional Regulation of Cardiac Pacemaker Cell Progenitors
Congenital and acquired defects of cardiac pacemakers are leading causes of morbidity and mortality in our society. Dysfunctions of the SA node and the lower conduction cells lead to a variety of complex arrhythmias that typically necessitate anti-arrhythmic therapy and implantation of devices. These treatments have significant limitations in their efficacy and risk-benefit ratio. Thus, […]
Identification of hESC-mediated molecular mechanism that positively regulates the regenerative capacity of post-natal tissues
The tissue regenerative capacity deteriorates with age in animals and in humans, leading to the loss of organ function, which is well exemplified in skeletal muscle, but is poorly understood in molecular terms. Our recent work uncovered that factors produced by human embryonic stem cells have a unique ability to enhance the regenerative responses of […]
