Exercise-related hormone irisin found to target key bone cells

Scientists have discovered that irisin, a hormone released by muscles during exercise, directly acts on key regulatory cells that control the breakdown and formation of bone. The researchers say this insight raises the prospect of new treatments for bone-thinning disorders such as osteoporosis. Reporting in Cell, Bruce Spiegelman and colleagues at Dana-Farber Cancer Institute say they have for… Read More »

Can stem cells help a diseased heart heal itself? Researcher achieves important milestone

A team of Rutgers scientists, including Leonard Lee and Shaohua Li, have taken an important step toward the goal of making diseased hearts heal themselves — a new model that would reduce the need for bypass surgery, heart transplants or artificial pumping devices. The study, recently published in Frontiers in Cell and Developmental Biology, involved… Read More »

Mechanism for turning skin cells into blood stem cells uncovered

Researchers have succeeded in converting human skin cells into blood stem cells in an international collaboration project.  “This is a first step on the way to generating fully functional blood stem cells in a petri dish which, in the future, could be transplanted into patients with blood diseases”, says Filipe Pereira, the researcher from Lund… Read More »
