The immune system promotes spontaneous heart regeneration

In adult mammal hearts, cardiomyoctyes do not proliferate following damage such as that caused by myocardial infarction. However, in some mammals, cardiomyocyte proliferation occurs. "Neonatal cardiomyocytes proliferate, ...

Scientists discover how to control heart cells using a laser

Scientists from MIPT's Laboratory of the Biophysics of Excitable Systems have discovered how to control the behaviour of heart muscle cells (cardiomyocytes) using laser radiation; this study will help scientists to better ...

Stem cell advance yields mature heart muscle cells

(Medical Xpress)—A team of University of Wisconsin-Madison researchers has induced human embryonic stem cells (hESC) to differentiate toward pure-population, mature heart muscle cells, or cardiomyocytes. A substrate patterned ...

Stem cells boost heart's natural repair mechanisms

Injecting specialized cardiac stem cells into a patient's heart rebuilds healthy tissue after a heart attack, but where do the new cells come from and how are they transformed into functional muscle?
