Children with Duchenne muscular dystrophy often die as young adults from heart and breathing complications. However, scientists have been puzzled for decades by the fact that laboratory mice bearing the same genetic mutation responsible for the disease in humans display only mild symptoms and no cardiac involvement. Now, researchers at the Stanford University School of Medicine have developed a mouse model that accurately mimics the course of the disease in humans. The study is the first...

For years, scientists have tried to understand why children with Duchenne muscular dystrophy experience severe muscle wasting and eventual death. After all, laboratory mice with the same mutation that causes the disease in humans display only a slight weakness. Now research by scientists at the Stanford University School of Medicine, and a new animal model of the disease they developed, points a finger squarely at the inability of human muscle stem cells to keep up with the ongoing damage...

Tissue regeneration a la salamanders and newts seems like it should be the stuff of science fiction. But it happens routinely. Why can't we mammals just re-grow a limb or churn out a few new heart muscle cells as needed? New research suggests there might be a very good reason: Restricting our cells' ability to pop in and out of the cell cycle at will "” a prerequisite for the cell division necessary to make new tissue "” reduces the chances that they'll run amok and form...

 Even cells aren't immune to peer pressure. Scientists at the Stanford University School of Medicine have now shown that skin cells can be coaxed to behave like muscle cells "” and muscle cells like skin cells "” solely by altering who they hang out with: the relative levels of the ingredients inside the cell.The fickleness of the cells, and the relative ease with which they make the switch, provide a glimpse into the genetic reprogramming that must occur for a cell to become...

Research will be presented at American Society for Cell Biology conferenceThe first demonstration that a single adult stem cell can self-renew in a mammal was reported at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.The transplanted adult stem cell and its differentiated descendants restored lost function to mice with hind limb muscle tissue damage.The adult stem cells used in the study, conducted at Stanford University, were isolated...

ambsace
  • Bad luck; misfortune.
  • The smallest amount possible or the most worthless thing.
The word 'ambsace' comes from a Latin word meaning 'both'.
