Modeling disease in human embryonic stem cells using new genetic tools
The use of stem cells or stem cell-derived cells to treat disease is one important goal of stem cell research. A second, important use for stem cells is the creation…
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…
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…
Long noncoding RNAs for pluripotency and cell fate commitment
The human body is composed of thousands of cell types, which all came originally from embryonic stem cells. Although all these cell types have the same genetic blueprint, different genes…
Role of the NMD RNA Decay Pathway in Maintaining the Stem-Like State
A subset of intellectual disability cases in humans are caused by mutations in an X-linked gene essential for a quality control mechanism called nonsense-mediated RNA decay (NMD). Patients with mutations…
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 (
Mechanisms to protect hESC-derived cells from allogenic immune rejection
The potential of human embryonic stem cells (hESC) to differentiate into a tremendous range of biologically active cells/tissues is the basis for many novel therapeutic strategies. However, immune-mediated rejection of…
Modeling Alexander disease using patient-specific induced pluripotent stem cells
Alexander disease (AxD) is a devastating childhood disease that affects neural development and causes mental retardation, seizures and spasticity. The most common form of AxD occurs during the first two…
Mechanism of heart regeneration by cardiosphere-derived cells
In the process of a heart attack, clots form suddenly on top of cholesterol-laden plaques, blocking blood flow to heart muscle. As a result, living heart tissue dies and is…
Deciphering transcriptional control of pancreatic beta-cell maturation in vitro
The loss of pancreatic beta-cells in type 1 diabetes results in absence of insulin secreted by the pancreas, and consequently elevated blood sugar which leads to various long-term complications. Diabetic…
