What are Stem Cells?
Stem cells are undifferentiated self regenerating multi potential cells. There are three types of stem cells categories by the ability to form after cells and correlated with the body’s development process. Totipotent: these stem cells can form an entire organism such as fertilized egg. Ploripotent: ploripotent cells are those that can form any cell in the body but cannot form an entire organ...
متن کاملResident Endothelial Cells and Endothelial Progenitor Cells Restore Endothelial Barrier Function After Inflammatory Lung Injury.
OBJECTIVE Disruption of endothelial barrier integrity is a characteristic of many inflammatory conditions. However, the origin and function of endothelial cells (ECs) restoring endothelial barrier function remain unknown. This study defined the roles of resident ECs (RECs) and bone marrow-derived endothelial progenitor cells (BMDEPCs) in endothelial barrier restoration after endotoxemic lung in...
متن کاملAre Stem Cells the next Therapeutic Tool for Heart Repair?
Cardiovascular disease remains the leading cause of morbidity and mortality in the United States and Europe. In recent years, the understanding that regenerative processes exist at the level of the myocardium, has placed stem cell research at center stage in cardiology. A stem cell is a cell that has the ability to divide (self replicate) for indefinite periods often throughout the life of the ...
متن کاملStem Cells and Lung Injury
The complex underlying mechanism for repair, proliferation, differentiation and remodeling after injury is a massive phenomenon in acute lung injury and their progression [1]. The recent progress in research shows the evidence that the stem cells may exhibit their trans-differentiation in organs including lung. The well established archetype of lung adult stem cells explored the knowledge about...
متن کاملCD34+ mesenchymal cells are a major component of the intestinal stem cells niche at homeostasis and after injury.
The intestinal epithelium is continuously renewed by intestinal epithelial stem cells (IESCs) positioned at the base of each crypt. Mesenchymal-derived factors are essential to maintain IESCs; however, the cellular composition and development of such mesenchymal niche remains unclear. Here, we identify pericryptal CD34+ Gp38+ αSMA- mesenchymal cells closely associated with Lgr5+ IESCs. We demon...
