Birth of new cardiac cells

A sophisticated imaging system, multi-isotope imaging mass spectrometry (MIMS), demonstrates cell division in the adult mammalian heart. Researchers were surprised to find that new heart muscle cells primarily arose from existing heart muscle cells, rather than stem cells.

Recent research has shown that there are new cells that develop in the heart, but how these cardiac cells are born and how frequently they are generated remains unclear.

In a study from Harvard-affiliated Brigham and Women’s Hospital (BWH), researchers used a novel method to identify the new heart cells and describe their origins.

The research was published today in Nature.

“The question about how

Human Lung Stem Cell Discovered

For the first time, researchers at Brigham and Women’s Hospital (BWH) have identified a human lung stem cell that is self-renewing and capable of forming and integrating multiple biological structures of the lung including bronchioles, alveoli and pulmonary vessels.  This research is published in the May 12, 2011 issue of the New England Journal of Medicine.

“This research describes, for the first time, a true human lung stem cell.  The discovery of this stem cell has the potential to offer those who suffer from chronic lung diseases a totally novel treatment option by regenerating or repairing damaged areas of the
