New method increases supply of embryonic stem cells

A new method allows for large-scale generation of human embryonic stem cells of high clinical quality. It also allows for production of such cells without destroying any human embryos. The discovery is a big step forward ...

New views of intracellular channel that controls skeletal muscle

Using high-resolution electron microscopy, Columbia University Medical Center (CUMC) researchers have uncovered new details of the structure and function of an intracellular channel that controls the contraction of skeletal ...

Special cells contribute to regenerate the heart in zebrafish

It is already known that zebrafish can flexibly regenerate their hearts after injury. An international research group led by Prof. Nadia Mercader of the University of Bern now shows that certain heart muscle cells play a ...

Gene alteration in mice mimics heart-building effect of exercise

By tweaking a single gene, scientists have mimicked in sedentary mice the heart-strengthening effects of two weeks of endurance training, according to a report from Dana-Farber Cancer Institute and Beth Israel Deaconess Medical ...

Scientists identify critical enzyme in healthy heart function

Scientists are reporting the first-ever data to show that the enzyme calcineurin is critical in controlling normal development and function of heart cells, and that loss of the protein leads to heart problems and death in ...

High vinculin levels help keep aging fruit fly hearts young

Our cells tend to lose their shape as we grow older, contributing to many of the effects we experience as aging. This poses particular problems for the heart, where aging can disrupt the protein network within muscle cells ...
