In research, induced pluripotent stem (iPS) cells are derived from skin, urine, or blood samples and developed into other cells, like heart tissue, that researchers want to study. Because of the ...

Columbia Engineering researchers have shown, for the first time, that electrical stimulation of human heart muscle cells (cardiomyocytes) engineered from human stem cells aids their development and ...

Structures called desmosomes connect cells to each other and transfer mechanical stress. They are especially important in tissues under continual mechanical stress, such as heart muscle (pictured).
