How do Circulating Precursor Endothelial Cells contribute to newly formed vessels

Endothelial cells derive from cells in the bone marrow. Circulating precursor endothelial cells contribute to newly forming vessels.

Do Alk 1 and/or Endogln mutations affect the functions of these cells once they incorporate into growing vessels. These vessels then go on to form arteriovenous malformations

Goal 2: Reduce Human Disease

Stem Cell Immunology

We now can create critical cell types like cardiomyocytes etc. from stem cells. Additionally, we are learning the rules of using these cells to rebuild tissues. A major gap in our knowledge relates to the immunobiology of these cells. Lessons from transplantation medicine are only partially applicable, because solid organs are more complex and likely more immunogenic than defined cell populations. How does the immune ...more »

Goal 2: Reduce Human Disease

Mitigating risks due to the RBC storage lesion and vulnerable patients

What are the underlying dependencies (genomic, metabolic, disease) in individual donors that either accelerate or delay the changes to red blood cells during refrigerated storage? What methods of preparation might protect patients from the risks posed by the accelerated degradation of RBCs provided by "poor storers"? What characteristics of individual patients make them particularly vulnerable to transfusion of red ...more »

Goal 3: Advance Translational Research

To find specific medical therapies to treat the wide array of human vascular malformations and vascular tumors.

Vascular malformations and vascular tumors, together referred to as vascular anomalies, comprise a complex and wide array of diseases in which there is a fundamental disruption in blood and lymphatic vasculature. The lesions disrupt organ function, destroy tissue, cause bleeding, increase infections and can threaten life. At present, there are some medical therapies but none are specifically targeted to an underlying ...more »

The coupling of mechanical stress to biochemistry, molecular biology and electrophysiology

Cells aren’t beakers holding soluble reactants waiting to be mixed. Cells are structured objects where life forms as a flow of free energy between three pools: chemical, electrical and mechanical. Most papers in the literature ignore structure (except of Xray or EM of specific proteins) and almost all ignore the coupling of mechanics to the other pools. Cells cannot be studied with in vitro experiments. We can study single ...more »

Goal 3: Advance Translational Research

Can hair follicle stem cells be transformed into new cells or organs?

Dr. Cotsarelis of the Univ. of Pennsylvania identified the bulge area of the hair follicle, which is now thought to contain the hair's stem cells. These cells would seem to be readily available and unique to an individual person. Can further work be done to transform these cells into now only hair cells but other organ tissues?

Regenerative Medicine 2.0 in Heart and Lung Research - Back to the Drawing Board

Stem cell therapies have been quite successful in hematologic disease but the outcomes of clinical studies using stem cells for cardiopulmonary disease have been rather modest. Explanations for this discrepancy such as the fact that our blood has a high rate of physiologic, endogenous turnover and regeneration whereas these processes occur at far lower rates in the heart and lung. Furthermore, hematopoietic stem cells ...more »

Mechanisms of Vascular Stiffness

Increased vascular stiffness has been identified as an important cardiovascular event that accompanies aging and cardiovascular disease. Although multiple vascular changes have been identified and suggested to cause increased vascular stiffness, our understanding of the underlying mechanisms needs to be refined in order to develop useful therapeutic strategies to prevent or reverse these changes. An example of critical ...more »
