Scientists discover new cell that could 'regenerate' diseased hearts

Could this reverse heart disease? Scientists discover special immune cell that could help the muscle heal itself - and they say it could cure the killer disease Scientists at the University of Calgary have discovered a new kind of immune cell in the fluid surrounding the heart  These cells, called pericardial macrophages, identify and 'eat' unhealthy cells Scientists believe they could supercharge the macrophages to regenerate heart muscle and treat heart disease

Scientists have discovered a cell that lives in the space surrounding the heart and which is capable of helping the heart heal itself. 

The heart is surrounded by a sac filled with liquid, called pericardial fluid. 

Although tests of the fluid can be used in diagnostics, its function has been otherwise poorly understood. 

University of Calgary researchers have discovered that this mysterious fluid contains macrophages, immune cells that help to repair the heart after injury and prevent heart muscle scarring. 

The team of scientists is optimistic that their discovery could be harnessed to help prevent or undo the damage of heart disease, the number one killer of Americans.

The heart is a unique organ in a number of ways, but one of its singular features actually helps to fuel the burden of heart disease. 

All organs age and start to deteriorate, but most are fairly proficient at repairing themselves until old age. 

But for all its strengths, the heart lags in this department and struggles to heal or repair itself. 

In people who have or are developing cardiovascular disease, the
