Staining of tubulin in a polyploid megakaryocyte (DJ. McCrann in Dr. Ravid’s lab)

Summary of research interest:

The cells of all blood lineages arise from pluripotent hematopoietic stem cells that reside in the marrow. The bone marrow also contains stem cells of other lineages, including fat, vascular etc. Our research is focused on two interrelated projects that bear on mechanisms associated with the development of blood and vascular pathologies: (1) molecular mechanisms involved in cell cycle control during the development of bone marrow megakaryocytes into platelets, a process that includes cellular polyploidization prior to platelet fragmentation. We also identified mechanisms of polyploidy in vascular smooth muscle cells, and found that the degree of polyploidy serves as an excellent biomarker for aging; (2) the role of vascular and bone marrow cell (progenitors and mature) adenosine receptors in vascular regeneration during injury or atherosclerosis. Transgenic and knockout models are used to assist in exploring mechanisms in vivo.
