After a decade of debate, scientists have a clear picture of a controversial protein that helps regulate heart contractions Brandeis University researchers have unlocked a controversial structure in heart cells responsible for regulating heart contractions. For years, scientists have debated how many KCNE1 proteins are required to build a potassium ion channel, theorizing anywhere between one and 14. Now, Brandeis University researchers found that these channels are built with two E1s....

Tokyo, Dec 17, 2013 - (ACN Newswire) - Beginning with their discovery of spontaneous oscillatory contraction (SPOC) of muscle, Prof. Shin'ichi Ishiwata and his team at Waseda University's Faculty of Science and Engineering have been experimentally characterizing this phenomenon over the last 25 years. Recently, the team, in collaboration with Dr. Katsuhiko Sato of the RIKEN Center for Developmental Biology (Kobe) and Vice Director Yoshiki Kuramoto of the International Institute for Advanced...

Sca1 Stem Cells Replace Steadily Ageing Heart Muscle Cells
2013-12-02 14:59:22

Max Planck Institute Up until a few years ago, the common school of thought held that the mammalian heart had very little regenerative capacity. However, scientists now know that heart muscle cells constantly regenerate, albeit at a very low rate. Researchers at the Max Planck Institute for Heart and Lung Research in Bad Nauheim, have identified a stem cell population responsible for this regeneration. Hopes are growing that it will be possible in future to stimulate the self-healing...

Study reverses understanding of heart cell development Mitochondria are the power plants of cells, manufacturing chemical fuel so a cell can perform its many tasks. These cellular power plants also are well known for their role in ridding the body of old or damaged cells. Now, researchers at Washington University School of Medicine in St. Louis and the University of Padua-Dulbecco Telethon Institute in Italy have shown that mitochondria remarkably also orchestrate events that determine...

You can't resurrect a dead cell anymore than you can breathe life into a brick, regardless of what you may have gleaned from zombie movies and Dr. Frankenstein. So when heart cells die from lack of blood flow during a heart attack, replacing those dead cells is vital to the heart muscle's recovery. But muscle tissue in the adult human heart has a limited capacity to heal, which has spurred researchers to try to give the healing process a boost. Various methods of transplanting healthy...

Atrium repairs ventricle If the heart following a heart attack is not sufficiently supplied with blood, heart tissue dies. In adult humans, the ability to heal itself is hardly developed. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim, together with U.S. colleagues, have now observed in the embryo of the zebrafish that muscle cells migrate from the undamaged atrium into the ventricle and thus significantly contribute to regeneration. This could serve as...

New Research Challenges 50 Years Of Muscle Knowledge
2013-07-10 10:54:49

Michael Harper for redOrbit.com - Your Universe Online For the past 50 years, scientists and health professionals have operated with the knowledge that biceps are packed with long ropes of filaments. When the bicep is used to lift a heavy object or flex, these filaments were understood to shorten or contract the muscle and give it its power. A new study from the University of Washington (UW) challenges this notion, saying that while the general idea of filaments contracting is the same,...

Studies in zebrafish reveal abundant potential source for repair of injured heart muscle In a study published in the June 19 online edition of the journal Nature, a scientific team led by researchers from the University of California, San Diego School of Medicine visually monitored the dynamic cellular events that take place when cardiac regeneration occurs in zebrafish after cardiac ventricular injury. Their findings provide evidence that various cell lines in the heart are more plastic,...

Mesp1 Gene Triggers Stem Cells To Become Heart, Blood Or Muscle
2013-05-03 18:37:33

Brett Smith for redOrbit.com — Your Universe Online When geneticists at the University of Minnesota began work on what they thought was a regulatory gene, they probably had no idea their work would redefine the tiny snippet of genetic material as a key player in stem cell differentiation. According to the team´s report in the journal Cell Stem Cell, the gene Mesp1 is responsible for differentiation of heart, blood and muscle cells from stem cells. “Previous research...
