When a muscle contracts, the parts of a sarcomere "shorten" and come closer together. Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events ...

Study shows that cardiac spheroids, derived from human induced pluripotent stem cells, can be easily transported and injected into damaged areas of the heart to promote its regeneration and recovery ...

Emerging research highlights the transformative potential of m6A RNA modification in the diagnosis and treatment of ...

Human heart muscle cells cease to multiply after birth, making any heart injury later in life a permanent one, reducing function and leading to heart failure. Now, however, researchers say they have ...

A recent study using mice has revealed a way to turn back the clock after heart attack. The researchers behind the work used RNAs to instruct cells in an injured heart to eliminate scar tissue and ...
