Scientists create mature heart muscle cells from stem cells

The mature heart muscle cells were created by implanting stem cells from a healthy adult or one with a type of heart disease into newborn rat hearts. The host hearts then give biological signals and chemistry necessary for the implanted immature heart muscle cells to overcome a developmental blockage that usually stops growth.

Soft Robot Helps the Heart Beat

Harvard University and Boston Children’s Hospital researchers have developed a customizable soft robot that fits around a heart and helps it beat, potentially opening new treatment options for people suffering from heart failure. The soft robotic sleeve twists and compresses in synch with a beating heart, augmenting cardiovascular functions weakened by heart failure.
