Differentiation of Human Embryonic Stem Cells to Intestinal Fates

The roughly 25 feet of intestine in the adult human play numerous essential roles in daily life, such as nutrient absorption, secretion of hormones, and serving as a barrier to infection. Commensurate with these diverse roles, diseases of the intestine are a considerable source of human morbidity and mortality. Indeed, numerous pathologic conditions including inflammatory […]

Technology for hESC-Derived Cardiomyocyte Differentiation and Optimization of Graft-Host Integration in Adult Myocardium

Stem cells therapies hold great promise in the treatment of cardiac diseases such as coronary heart disease or congestive heart failure. Thanks to their ability to transform into almost any kind of tissue, engrafted stem cells can potentially replace damaged heart tissues with healthy tissues, effectively restoring the heart’s original functions. While initial studies demonstrated […]

Micro Platform for Controlled Cardiac Myocyte Differentiation

Congestive heart failure, the inability of the heart to continue to pump effectively due to damage of its muscle cells, affects approximately 4.8 million Americans and is a leading cause of mortality. Causes of the irreversible damage to the cardiomyocytes that results in congestive heart failure include hypertension, heart attacks, and coronary disease. Because the […]

Derivation and Characterization of Cancer Stem Cells from Human ES Cells

Cancer is the leading cause of death for people younger than 85 (1). High cancer mortality rates underscore the need for more sensitive diagnostic techniques as well as therapies that selectively target cells responsible for cancer propagation (1) Compelling studies suggest that human cancer stem cells (CSC) arise from aberrantly self-renewing tissue specific stem or […]

Identifying small molecules that stimulate the differentiation of hESCs into dopamine-producing neurons

In this application, we propose to identify small molecule compounds that can stimulate human embryonic stem cells to become dopamine-producing neurons. These neurons degenerate in Parkinson’s disease, and currently have very limited availability, thus hindering the cell replacement therapy for treating Parkinson’s disease. Our proposed research, if successful, will lead to the identification of small […]

Human Embryonic Stem Cell Differentiation to Trophoblast: Basic Biology and Clinical Translation to Improve Human Fertility

In addition to the important potential applications for transplantation and treatment of chronic diseases, human embryonic stem cells (hESC) are also a valuable resource to study early human development relevant to fertility and healthy pregnancies. After fertilization, the human zygote undergoes cell divisions and ultimately becomes the blastocyst that has an inner cell mass and […]

MicroRNA Regulation of Human Embryonic Stem Cell Self-Renewal and Differentiation

A major hurdle for regenerative medicine is the safe transplantation of human embryonic stem (ES) cells or their derivatives into patients. While the unlimited growth potential of ES cells is a major asset for their potential in tissue replacement, it is also a major risk for tumorigenesis. Therefore, it is critical to determine what molecules […]

Role of Glycans in Human Embryonic Stem Cell Conversion to Neural Precursor Cells

Like a thick frosting on a cake, complex sugar chains decorate every surface of every cell. Try to approach a cell, as friend or foe, and the canopy of sugars is the first gate-keeper. Each cell makes and organizes these sugar chains, called glycans, on its surface. They are very complicated molecules, and different cells […]

Specification of Ventricular Myocyte and Pacemaker Lineages Utilizing Human Embryonic Stem Cells

Heart failure is a leading cause of mortality in California and the United States. Currently, there are no “cures” for heart failure.Other life threatening forms of heart disease include dysfunction of cardiac pacemaker cells, necessitating implantation of mechanical pacemakers. Although mechanical pacemakers can be efficacious, there are potential associated problems, including infection, limited battery half-life, […]
