Surgeons have used stem cells from fat to help repair skull damage in a seven-year-old girl in Germany.

The girl had been injured two years before in a fall, which destroyed several areas of her skull totaling nearly 19 square inches, the German researchers reported.

Other surgeons had failed to correct the defects, and the girl wore a protective helmet. Her brain could sometimes be seen pulsating through the missing areas of her skull.

But several weeks after the stem-cell surgery, she was able to leave her helmet behind, the researchers report in the December issue of the Journal of Cranio-Maxillofacial Surgery.
