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 whic
A. his work made an unprecedented achievement in the field
B. he proved that ADAS cells contributed a lot to cell therapy
C. his work paved way for ADAS cell application in clinical trials
D. he cured an animal defect that had never been repaired before

| Early to bed, early to rise, makes a
man healthy, wealthy (富有的) and wise (聪明的). This is an old English saying. Have you ever heard it before It means that we must go to bed early and get up early in the morning. Then we shall be healthy, and we shall also be rich and clever. This is true. The body must have enough sleep to be healthy. Children at young ages should have ten hours’ sleep every night. Children who do not have enough sleep can not do their work very well. They will not be clever and they may not become rich. The body also needs exercise. Walking, running, jumping, swimming and playing games are all exercise. Exercise keeps the body strong. Exercise also helps the blood (血液) to move around inside the body. This is very important. Our blood takes food to all parts of our body. The head also needs blood. Exercise helps us to think [单项选择]Communication satellites generally use solar cells as their source of electric power, although some test satellites have used thermoelectric generators.
