Transcript of Stem Cells

Stem Cells Stem cells retain the ability to divide and have the ability to differentiate along different pathways. Cardiovascular Disease has been the number one cause of death in the United States every year since 1900 except for 1918. What is Cardiovascular Disease? Cardiovascular disease can deprive the heart of oxygen which, in turn, kills cardiac muscle cells (cardiomyocytes) A possible new therapy as a prevention of heart failure is to restore damaged muscle tissue through repair or regeneration. This is where stem cells come in... Scientists have been researching a way to use embryonic and adult-derived stem cells for cardiac repair. Many different specialized cell types have been tested for the use of cardiac repair in animals such as mice, rats, and some cell types have been tested in larger animals like pigs. A few studies have been tested on humans undergoing open heart surgery. The stem cells have been injected into the circulation or directly into the damaged heart tissue. Many of the cases have improved the patients' cardiac function. However, this means of repair remains very controversial and results vary widely. But through more research stem cells could be a leading contributor to ending the death rate of patients with cardiovascular disease.
