Non-invasive live imaging of stem cell signature metabolic states
Stem cells in tissues exhibit unique metabolic states that could distinguish them from other more specialized cells. Using a new type of microscopy we can image the metabolic states of cells in living tissues and, therefore, attempt to identify stem cell populations. Because stem cells can give rise to tumors that are metabolically very different […]
Directed Differentiation of Specialized Endothelial Cells
Vascular endothelial cells (EC) or endothelial progenitor cells (EPC) derived from stem cells could potentially lead to a variety of clinically relevant therapeutic applications, including various strategies for treating heart and vascular diseases. However, because EC exhibit a variety of functionally distinct subphenotypes, it is important to be able to generate the appropriate endothelial type. […]
Engineered matrices for control of lineage commitment in human pancreatic stem cells
Patients with end-stage type 1 diabetes (T1D) can be effectively managed by allogeneic islet transplantation. However, a severe cadaveric organ shortage greatly limits use of this promising procedure. Stem cells have the potential to provide a solution to this bottleneck because of their ability to self-renew and differentiate into islet β-cells. Although progress has been […]
Role of intracytoplasmic pattern recognition receptors in HSC engraftment
The research performed through this project is very important for the fields of solid organ and bone marrow transplantation because it focuses on a potential new target to increase engraftment of stem cells. Currently, patients that receive stem cell transplants from a non-identical donor must take medications to suppress their immune system; otherwise the stem […]
Assessing the mechanism by which the Bone Morphogenetic Proteins direct stem cell fate
Our goal is to use the mechanisms that generate neuronal networks to create neurons from stem cells, to either replace diseased and damaged tissue or as a source of material to study disease mechanisms. A key focus of such regenerative studies is to restore function to the spinal cord, which is particularly vulnerable to damage. […]
Innate Immune Regulation of Lung Alveolar Stem Cell Renewal in Mouse and Man
The lung, along with the skin and gut are the three organs in perpetual contact with our environment. The lung has evolved mechanisms for repairing injury due to exogenous noxious agents. The timely repair of lung injury is essential and determines the outcome of life or death. The mechanisms that regulate mature alveolar epithelial stem […]
New Regulators of Spermatogonial Stem Cells: RHOX Homeobox Transcription Factors
Infertility afflicts a remarkably high percentage (~15%) of couples, with male factor defects being responsible for more than ½ of these cases. One-third of these male infertility cases have no known cause. For most infertile men, the only “treatment” is in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), both of which are costly, invasive […]
Differentiation of Human Hematopoietic Stem Cells into iNKT Cells
Blood stem cells living in the bone marrow of adult humans give rise to all of the cells in our blood, including the red blood cells that carry oxygen to supply our body, and the white blood cells such as T and B lymphocytes that fight infections and keep us healthy. Among the T lymphocytes […]
