Molecular regulation of stem cell potency
The field of stem cell biology as it applies to regenerative medicine requires a detailed understanding of what controls stem cell function. Our fundamental interest is in the molecular pathways…
Neural restricted, FAC-sorted, human neural stem cells to treat traumatic brain injury
Traumatic brain injury (TBI) affects 1.4 million Americans a year; 175,000 in California. When the brain is injured, nerve cells near the site of injury die due to the initial…
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…
Regulation of Stem Cell Fate in Bioengineered Arrays of Hydrogel Microwells
Stem cell biology, since its inception 30 years ago, has been hindered by our limited ability to observe and direct the decisions of individual stem cells. In the case of…
Skeletogenic Neural Crest Cells in Embryonic Development and Adult Regeneration of the Jaw
The goal of this proposal is to develop cell-based therapies that lead to the better healing of traumatic head injuries. Our first strategy will be to use genetics and embryology…
Immunology of neural stem cell fate and function
One of the most difficult yet ultimately rewarding goals in stem cell research is to repair damaged neural systems with newly generated neurons. Our work examining neuronal integration and survival…
New Chemokine-Derived Therapeutics Targeting Stem Cell Migration
This proposal describes a sharply-focused, timely, and rigorous effort to develop new therapies for the treatment of injuries of the Central Nervous System (CNS). The underlying hypothesis for this proposal…
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…
