Regenerative heart therapies involve transplanting cardiac muscle cells into damaged areas of the heart to recover lost function. However, the risk of arrhythmias following this procedure is ...

One promising strategy to remuscularize the injured heart is the direct cardiac reprogramming of heart fibroblast cells into cardiomyocytes. Researchers have identified TBX20 as the key missing ...

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 ...

Mount Sinai's Cardiovascular Research Institute is sending bioengineered human heart muscle cells and micro-tissues into space for the first time on NASA's 29 th SpaceX commercial resupply services ...

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 ...
