Medical school professor recognized nationally for research on bone growth

Medical school professor recognized nationally for research on bone growth University of South Dakota Professor Daniel Neufeld has garnered national recognition for his research on bone regeneration conducted at USD.

His most recent article titled "Bone Growth is Induced by Nail Transplantation in Amputated Proximal Phalanges" was published in the Calcified Tissue International Journal. Neufeld's work has also been cited in New Scientist, a scientific journal that regularly conducts overviews of recent research developments.

"The idea of regeneration first appealed to me as a freshman in college biology," said Neufeld. "When I heard in a lecture that some animals can grow their limbs back, I wondered, 'why can't we?'"

The research that has generated so much attention is based on the premise that it may be possible for mammals to regenerate partially amputated limbs. Neufeld's work included transplanting the toenail and its bed from the amputated toe of a rat to an amputation site higher up the limb. In some instances, this transplant caused the regeneration of a normal looking toe.

"The research we are doing is provoking the interests of other researchers," said Neufeld.

But researchers haven't been the only interested parties. According to Neufeld, he has even received a call from BBC World Radio.

"Hopefully, this research will allow the medical school to be more competitive when we apply for research grants," he said.

Neufeld has been a professor at The University of South Dakota since 1977. He has been studying regeneration since doing his doctoral dissertation on toe regeneration in mice in 1972. Neufeld earned his B.A. degree from UCLA and his Ph.D from Tulane.
