Marrow Hematopoietic Stem Cells Revisited: They Exist in a Continuum and are Not Defined by Standard Purification Approaches; Then There are the Microvesicles
Current concepts of hematopoiesis are encompassed in a hierarchical stem cell model. This developed initially from studies of colony-forming unit spleen and in vitro progenitors for different cell lineages, but then evolved into a comprehensive model of cells with different in vivo differentiative and proliferative potential. These cells were characterized and purified based largely on expressi...
متن کاملWhat 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 کاملCardiac Stem Cells for Myocardial Regeneration: They Are Not Alone
Heart failure is the number one killer worldwide with ~50% of patients dying within 5 years of prognosis. The discovery of stem cells, which are capable of repairing the damaged portion of the heart, has created a field of cardiac regenerative medicine, which explores various types of stem cells, either autologous or endogenous, in the hope of finding the "holy grail" stem cell candidate to slo...
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 ...
