BACKGROUND The identification and isolation of human cardiac progenitor cells (hCPCs) offer new approaches for myocardial regeneration and repair. Still, the optimal source of human cardiac progenitor cells and the influence of patient characteristics on their number remain unclear. Using a novel method to isolate human cardiac progenitor cells, we aimed to define the optimal source and associa...
Background—The identification and isolation of human cardiac progenitor cells (hCPCs) offer new approaches for myocardial regeneration and repair. Still, the optimal source of human cardiac progenitor cells and the influence of patient characteristics on their number remain unclear. Using a novel method to isolate human cardiac progenitor cells, we aimed to define the optimal source and associa...
The isolation and culturing of cardiac progenitor cells has demonstrated that growth factor signaling is required to maintain cardiac cell survival and proliferation. In this study, we demonstrate in Xenopus that SHP-2 activity is required for the maintenance of cardiac precursors in vivo. In the absence of SHP-2 signaling, cardiac progenitor cells downregulate genes associated with early heart...
Cardiac muscle creation during embryogenesis requires extracellular instructive signals that are regulated precisely in time and space, intersecting with intracellular genetic programs that confer or fashion the ability of the cells to respond. Unmasking the essential signals for cardiac lineage decisions has paramount importance for cardiac development and regenerative medicine, including the ...
The high occurrence of cardiac disease in the Western world has driven clinicians and cardiovascular biologists to look for alternative strategies to treat patients. A challenging approach is the use of stem cells to repair the heart, in itself an inspiring thought. In the past 10 years, stem cells from different sources have been under intense investigation and, as a result, a multitude of stu...
The concept that adult stem/progenitor cells can differentiate into either hematopoietic or nonhematopoietic tissues is supported by a considerable amount of reviewed data (1). Adult mononucleated cells (MNC) containing the stem/ progenitor cell fraction can be isolated from mobilized peripheral blood and bone marrow (BM) tissue by density gradients (2). BM MNC also contain mesenchymal stromal ...
Background: Exercise and the simultaneous use of progenitor cells is a new strategy aimed for reducing diabetic disorders. One of the known mechanisms is angiogenic disorders caused by diabetes. Therefore, the present study was performed to determine the simultaneous effect of resistance training with endothelial progenitor cell injection on the expression of angiogenic factors in the skeletal ...
The recent identification of progenitor populations that contribute to the developing heart in a distinct spatial and temporal manner has fundamentally improved our understanding of cardiac development. However, the mechanisms that direct atrial versus ventricular specification remain largely unknown. Here we report the identification of a progenitor population that gives rise primarily to card...
