From the article: "To calm this overzealous receptor, molecular biologist Elvire Gouze of INSERM in Nice, France, and colleagues resorted to deception. They repeatedly injected a solution of FGFR3 into mice that had a growth-hindering condition equivalent to achondroplasia. The researchers hypothesized that these free-floating copies of the receptor would serve as decoys, capturing fibroblast growth factor molecules and reducing stimulation of the cartilage cells’ receptors. That’s what appeared to happen. The treatment restored normal growth in the mice and forestalled skeletal defects characteristic of achondroplasia, the researchers report online today in Science Translational Medicine. Injections of the decoy cut the percentage of mice that showed abnormal curvature of the spine from 80% to as little as 6%, depending on the dose. When the treated mice matured, the females gave birth to normal numbers of pups, another sign that the skeleton—specifically, the pelvis—had reached full adult size."
I also remember (from perhaps a year or two ago?) the story of the doctors in Europe replaced someone's diseased trachea and got the "new part" by using the patient's own stem cells to grow a new one in the lab. I believe doctors/researchers from three different European countries were involved.
