Genetic manipulation of human embryonic stem cells and its application in studying CNS development and repair

The advent of human embryonic stem cells (hESCs) has offered enormous potential for regenerative medicine and for basic understanding of human biology. On the one hand, hESCs can be turned into many different cell types in culture dish, and specific cell types derived from hESCs offer an almost infinite source for cellular replacement therapies. This […]

Modeling Parkinson’s Disease Using Human Embryonic Stem Cells

Parkinson’s disease (PD) is the most frequent neurodegenerative movement disorder caused by damage of dopamine-producing nerve cells (DA neuron) in patient brain. The main symptoms of PD are age-dependent tremors (shakiness). There is no cure for PD despite administration of levodopa can help to control symptoms. Most of PD cases are sporadic in the general […]

Embryonic stem cell-derived thymic epithelial cells

The function of the immune system throughout life is essential for protection from infections and cancer. T lymphocytes are white blood cells that choreograph the multiple responses that the body uses to control infection. T lymphocytes are produced in the thymus, a specialized organ located in the chest in front of the heart. The production […]

Self-renewal of human embryonic stem cells

Human embryonic stem (ES) cells are a remarkable cell type that are derived from a group of cells called the inner cell mass (ICM) of a very early stage embryo (about 100 cells in total) obtained from in vitro fertilization program. Human ES cells can be expanded in culture in an undifferentiated state (self-renewal) without […]

hESCs for Articular Cartilage Regeneration

Mobility is critical for human social interactions and quality of life. In the aged mobility is progressively impaired due to painful joints. The articular cartilage in the joints is damaged. The long-term goal of our research is the utilization of human embryonic stem cells (hESCs) for cartilage formation and therefore, regeneration of articular cartilage. Stem […]

Improving microenvironments to promote hematopoietic stem cell development from human embryonic stem cells

Hematopoietic stem cells (HSC) have been used successfully to cure various life-threatening blood diseases. Yet, matching HSCs are not available for every patient. Human embryonic stem cells (hESC) may provide an unlimited source of HSCs for therapeutic use. However, hESC derived hematopoietic cells do not develop properly in those culture conditions that are currently used, […]

In Vitro Differentiation of T cells from Human Embryonic Stem Cells.

White blood cells are the main players of human immunity in defense against infection. Defects in CD4 T white blood cells, for example, can lead to the devastating infections observed in AIDS patients and patients with a genetic immunodeficiency syndrome (“bubble boy” syndrome). A normal immune system can recognize and attack pathogens but not “self”. […]

Trophoblast differentiation of human ES cells.

Human embryonic stem (ES) cells have the potential to form any cell type, but ironically, the first cell lineage to form during development still represents a surprising challenge. The first cell type to become specialized is an epithelial cell that later defines the boundary between the embryo and mother for the formation of the placenta. […]

Gene regulatory mechanisms that control spinal neuron differentiation from hES cells.

More than 600 disorders afflict the nervous system. Common disorders such as stroke, epilepsy, Parkinson’s disease and autism are well-known. Many other neurological disorders are rare, known only to the patients and families affected, their doctors and scientists who look to rare disorders for clues to a general understanding of the brain as well as […]

Modeling Human Embryonic Development with Human Embryonic Stem Cells

Stem cells have entered the public consciousness as “cells that can do anything” and have been hailed as a panacea in the fight against disease, aging and cancer. Unfortunately, we have only scratched the surface in understanding these cells. Some of the things we think we know are that: embryonic stem cells hold great promise […]
