DNA repair and cell repair: Are they related?
International Journal of Radiation Oncology*Biology*Physics, 1979Abstract Evidence of damage-repair processes is reviewed in connection with 3 types of cytotoxic cell treatments: X-radiation; far-ultraviolet (UV) (254 nm) light; and fluorescent light (FL) exposure of cells that had been grown in the presence of 5-bromodeoxyuridine (BUdR).

Current Opinion in Biotechnology, 2009
The liver has considerable inherent regenerative capacity through hepatocyte division and hepatic progenitor cell proliferation. In chronic disease regeneration eventually fails and liver transplantation is the only curative treatment. Current work aims to restore liver mass and functionality either through transplantation of stem cell derived ...

Mechanical injury and repair of cells
Critical Care Medicine, 2003To concisely review the field of cell plasma membrane disruption (torn cell surface) and repair.Plasma membrane disruption is a common form of cell injury under physiologic conditions, after trauma, in certain muscular dystrophies, and during certain forms of clinical intervention. Rapid repair of a disruption is essential to cell survival and involves

Injury and Repair of Liver Cells
Medical Clinics of North America, 1979Alterations in hepatocytes, progressing to necrosis, are the morphologic basis for the main clinical manifestations and aberrations in hepatic test results in acute and chronic liver disease. The light-microscopic manifestations of hepatocellular injury, the mechanisms of necrosis, the light-microscopic features of repair and regeneration, and the ...

Stem Cells and Myocardial Repair
Journal of the American College of Surgeons, 2002Myocardial ischemia sends a warning signal to subtended cardiomyocytes that can both promote protection by preconditioning and result in contractile dysfunction or stunning. If the ischemic period is brief ( 20 minutes), cardiomyocytes survive, contractile function recovers, and the myocardium becomes relatively resistant to subsequent ischemic insult.

Progress in Retinal and Eye Research, 2004
Retinal stem cells (RSCs) are multipotent central nervous system (CNS) precursors that give rise to the retina during the course of development. RSCs are present in the embryonic eyecup of all vertebrate species and remain active in lower vertebrates throughout life.

Progenitor cells in vascular repair
Current Opinion in Lipidology, 2007A common characteristic of all types of vascular disease is endothelial dysfunction/damage followed by an inflammatory response. Although mature endothelial cells can proliferate and replace damaged cells in the vessel wall, recent findings indicate an impact of stem and progenitor cells in repair process.

Progenitor cells for cardiac repair
Seminars in Cell & Developmental Biology, 2007Repair of diseased or injured myocardium by cell-based therapies is likely to require a multi-pronged approach. New myocytes will need to be generated, integrated with existing myocardial tissue, and perfused with a newly acquired vascular system.

Repair processes and cell survival
The British Journal of Radiology, 1972Abstract A model of cell survival after irradiation is presented which explicitly incorporates a repair process. The model is based on Powers' suggestion of a “pool”, and is developed along the lines initiated by Lajtha and Oliver (1961). The repair process corresponding to the shoulder on the survival curve is distinguished from the process ...

Future Cardiology, 2010
Myocardial infarction is the leading cause of death among people in industrialized nations. Although the heart has some ability to regenerate after infarction, myocardial restoration is inadequate. Consequently, investigators are currently exploring the use of human embryonic stem cells (hESCs), skeletal myoblasts and adult bone marrow stem cells to ...
