Polarity gene yields clues to organization of cell signaling, structural growth
Researchers are beginning to understand how a gene called “stardust” works to set up the basic top-down architecture of the epithelial cells that line the gut, skin, and many other organs of an...
View ArticleDiscovery could aid in therapeutic cloning, clamping down on cancer
“Our focus is to understand the very first few steps that drive a cell to become an intestinal cell instead of a muscle cell,” says Yang Shi, Harvard Medical School associate professor of pathology....
View ArticleResearchers use therapeutic cloning to create functional tissue in cows
In a study, researchers obtained cow oocytes (donor eggs from cow ovaries) and removed and discarded the nuclei, which contain the cells’ genetic material, leaving behind just the shell. A skin cell...
View ArticleMajor progress toward cell reprogramming
Two Harvard Stem Cell Institute (HSCI) researchers and scientists at Whitehead Institute and Japan’s Kyoto University have independently taken major steps toward discovering ways to reprogram cells in...
View ArticleStem cell lines created from discarded IVF embryos
Human embryos that are discarded every day as medical waste from in vitro fertilization (IVF) clinics could be an important source of stem cells for research, according to a team of Harvard Stem Cell...
