For the first time, stem cells purified from fat have been used to heal an injury in a living animal. Michael Longaker of Stanford University in California and his team showed in mouse experiments that so-called adipose derived adult stromal (ADAS) cells purified from a rodent’s belly fat could be coaxed to heal a skull fracture too large to mend by itself.
The power of ADAS cells to transform into bone, cartilage and even neurons has been studied for years in test tubes. But Jeffrey Gimble, who studies human ADAS cells at Louisiana State University in Baton Rouge says Longaker’s report is an important step forward. "Actually repairing a defect in an animal model had never been done. This is an excellent study." If the same technique works in humans, these cells could be coaxed to mend broken bones and correct other defects in tens of thousands of surgical procedures each year in which bone grafts and prosthetics are now necessary.

Hippocrates, the "Father of Medicine", said, "Let your food be your medicine, and let your medicine be your food." For a Greek born in the fifth century B. C. , Hippocrates was wise beyond his time. Today, we know that a low-fat diet rich in whole grains, fruits, and vegetables strengthens the immune system and reduces the risk of cancer, heart disease, and stroke. But, Hippocrates, lend an ear ! There’s more to the story. New evidence suggests that food may influence how healthy people think and feel. Were he alive today, Hippocrates might look back to his last meal to explain his che
