Surprise cell death discovery provides birth defect clues
Researchers have made a surprise discovery that could rewrite our understanding of the role programmed cell death plays in embryonic development and congenital birth defects. The team showed that, while programmed cell death -- or apoptosis -- is essential for healthy development overall, many organs and tissues do not require apoptosis to develop normally. The study also suggested that abnormalities in cell death processes are likely to contribute to some common birth defects in humans, such as spina bifida, heart vessel defects and cleft palate.

How new blood vessels form in mammals, for example during development or after injury, was so far not known exactly. Scientists at the Goethe University have now been able to shed light on this process.

Increased nerve activity may raise blood pressure in anxiety
Sympathetic nerve activity to skeletal muscle blood vessels--a function of the nervous system that helps regulate blood pressure--increases during physiological and mental stress in people with chronic anxiety, a new study finds. Over time, this response may increase the risk of high blood pressure and heart disease, although the study did not test this specifically. The study, published ahead of print in the Journal of Neurophysiology, is an APSselect article for May. (2018-05-03)

Heart disease symptoms improved by blocking immune cell migration
New research led by investigators at Case Western Reserve University School of Medicine and University Hospitals Cleveland Medical Center suggests that the location of immune cells in the body determines whether they help or harm the development of heart disease. The study supports the view that the immune system directly impacts heart failure -- still the leading cause of death for men and women in the United States. (2018-05-02)

Who am I? How cells find their identity
The research group of Alex Schier, Director of the Biozentrum, University of Basel, has investigated more closely how a single embryonic cell develops into a heart, nerve or blood cell. For the first time, the researchers have been able to reconstruct the developmental trajectories of individual embryonic cells. Their results also suggest that cells can change their path during their maturation process. The results of the study with around 40,000 cells have now been published in Science. (2018-04-26)

Exercise could make the heart younger
After a heart attack, patients must create new heart muscle cells to heal. Harvard study shows that mice make more new heart muscle cells when they exercise compared to when they do not. This was true for both healthy mice and those that had experienced a heart attack. Findings demonstrate that one reason exercise is beneficial to health is that it increases the heart's capacity to regenerate. (2018-04-25)

New cell therapy aids heart recovery -- without implanting cells
A team led by Columbia University Biomedical Engineering Professor Gordana Vunjak-Novakovic has designed a creative new approach to help injured hearts regenerate by applying extracellular vesicles secreted by cardiomyocytes rather than implanting the cells. The study shows that the cardiomyocytes derived from human pluripotent stem cells (derived in turn from a small sample of blood) could be a powerful, untapped source of therapeutic microvesicles that could lead to safe and effective treatments of damaged hearts. (2018-04-23)
