The sturdier sex? -- Study by Pittsburgh scientists finds female stem cells work better

...ab while searching for a cure for Duchene muscular dystrophy (DMD). DMD is a genetic disease estimated to affect one in every 3,500 boys. Patients with DMD lack dystrophin, a protein that gives muscle cells structure. Using an animal model of the disease, his laboratory is using stem cells to deliver dystrophi...

FSU biologists uncover mechanisms that shape cells for better or worse

...in fruit fly eggs may help to clarify how muscular dystrophy and some cancers develop in humans. That's because many of the genes involved in the cell-to-cell communication that triggers the development of cell polarity in Drosophila oocytes (unfertilized fruit fly eggs) also are known players in the pathoge...

Even severe diseases like Duchenne muscular dystrophy (DMD), which destroys all the body's muscles, appeared to be potentially treatable ?indeed, by the simple means of transplanting healthy bone marrow. For boys, DMD is the second most common hereditary disease. Due to a genetic defect, the muscles fai...
