Artificial Embryos Made from Stem Cells Raise Ethical Issues

Stem cells (so-called “master cells”) are unique and important in the body because they can do almost anything, and scientists have only begun to discover their potential. That’s why researchers’ use of them has created controversy, attracting the attention of scientists, policymakers, and bioethicists across the globe. Stem cells can transform into any of the… Read More »

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 »

Japanese researchers inject stem cells into patient's brain to treat Parkinson's in historic first

Japanese researchers said Friday they have transplanted stem cells into the brain of a patient in the first stage of an innovative trial to cure Parkinson’s disease. The research team at Kyoto University injected induced Pluripotent Stem (iPS) cells — which have the potential to develop into any cell in the body — into the… Read More »
