Ruiz-Lozano Cardiac Development and Disease Research Laboratory
300 Pasteur Dr., Suite A359
Department of Pediatrics (Cardiology)
Stanford University School of Medicine
Current Research Interests
Heart failure and coronary artery disease are leading clinical problems in the western countries with limited therapeutical options (www.americanheart.org). The heart, however, has endogenous mechanisms of repair that could potentially be enhanced pharmacologically and be used as novel approaches for treatment. Based on a genetic, stem cell and biochemical approaches, research in the Ruiz-Lozano’s laboratory focuses on the discovery, analysis and applications of endogenous cardiac repair systems with particular emphasis on the role of epicardial progenitor cells. Current projects in the laboratory include: 1. The determination of the fate of coronary progenitor cells from the epicardium and their response to growth signals. 2. The potential of epicardial cells to modulate cardiac morphogenesis. 3. Adaptation mechanisms of the heart to stress and aging.
Among the achievements of the laboratory is the generation of the first animal model targeting specific mutations to coronary progenitor cells and the identification of genetic pathways that regulate cardiac growth and coronary formation. A major effort is committed to the isolation of progenitor cells and tissue repair.

    FEATURED RESEARCH
    Grafting 3D Collagen Scaffolds onto Infarcted Myocardium Influences Cardiac Remodeling and Neo-angiogenesis
    Principle investigator: Vahid Serpooshan
    Patients who survive acute myocardial infacrtions are left with damaged ventricles which often lead to heart failure, even without another ischemia. Humans and other mammals possess limited capacity for myocardial regeneration, insufficient to restore heart function after injuries. In spite of the apparent success of exploiting cardiac stem (progenitor) cells as treatment for heart tissue injury, there have been controversial reports about the effciciency of cell therapy techniques, the fate of the cells, and their role in cardiac regeneration.
    It has been shown that grafting biocompatible patches onto the infarcted myocardium can imrpve cardiac tissue repair post ischemia. This study aims to investigate the influence of multilayered microstructure, mass transfer properties, and stiffness of grafted 3D collagen scaffolds in cardiac remodeling processes including ventricular dilation, angiogenesis, fate of cardiac stem cells, their migration, proliferation, gene expression, and signalling pathways. Moreover, the use of 3D scaffolds as delivery devices for various cell phenotypes and macromolecules will be assessed. The ultimate clinical goal is to develop a grafting technique to mount biomimetic matrices onto the heart in patients with acute MI.
    Stretch Regulated Response of the Notch Pathway in EMCs
    Principle investigator: Scott Metzler
    The elucidation of mechanisms involved in cardiogenesis on a cellular and molecular level is necessary for the development of potential cell-based therapies for both degenerative adult diseases and congenital abnormalities of the heart. The mechanical environment of the embryonic heart has recently been shown to be critical in regulating differentiation and determination of cell fate in cardiogenesis. However, investigating the role of mechanical forces in epicardial function during development has been a relatively recent undertaking. Therefore, there is a critical need for a comprehensive understating of the complex interplay of mechanical forces and the role of the epicardium in development.

    The aim of this study is to further our fundamental knowledge of the epicardium and ascertain how exogenous mechanical stimuli can contribute to cardiogenesis and differentiation.
