Stem cells from fat used to repair skull damage
AP via MSNBC:
Surgeons have used stem cells from fat to help repair skull damage in a 7-year-old girl in Germany, in what’s apparently the first time such fat-derived cells have been exploited to grow bone in a human.There is certainly an abundant supply of source material for this type of procedure.
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. The skull is now smooth to the touch, the missing parts replaced by thin but solid bone, said Dr. Hans-Peter Howaldt of the Justus-Liebig-University Medical School in Giessen, Germany. The child was not identified.
Howaldt, who performed the surgery last year, said the damage was too extensive to be repaired with bone grafts from her body. He said the hope was that if bits of the child’s bone were mixed with stem cells, the cells would turn into bone-building cells that would create additional bone.
That appears to have happened, Howaldt said in a telephone interview Thursday.
