Cardiac Stem Cells vs. The Heart Attack

Currently at the University of Vermont, Professor Jeffrey Spees, Ph.D. and other researchers have been working towards the invention of a method to combat cardiac problems.  Hundreds of thousands of people have heart attacks every year and sadly many die from it.  The use of stem cells has been key to the work done thus far to hinder the ailments of the heart.  Stem cells can be grown to any particular cell the body needs.  They are used to regrow or repair damaged cells in the body.  Once the cells are grown they need to be grafted into position, which can prove very difficult.  

The lack of adhesion and death are among the most common forms of stem cell graft failures.  To aid in this problem, the researchers used progenitor cells made from bone marrow, which has the ability to form stromal cells that help with blood cell formation.  The ligands secreted by these cells help the stem cells to attach and thrive in the body.  This method allowed for the cardiac stem cells to be successfully placed in the heart of a rat, which proved to be the most successful trial to date.  Although human application has not been attempted yet, the results are very promising thus far.
