The Pentagon has made its first significant development with ‘induced’ stem cells (stem cells not obtained from embryos) to regenerate the limbs of amputees who fought in the wars in Iraq and Afghanistan. Researchers were successful in transforming epithelial cells, which were manipulated to regress to their primordial state, into blastemas. A blastema is a mass of undifferentiated cells, which can develop into new body parts. In nature, blastemas are present in salamanders, and newts, animals, which are capable of restoring their own limbs with functionality after amputation.
The final goal, which is still far
Broken bones in humans and animals are painful and often take months to heal. Studies conducted in part by University of Georgia Regenerative Bioscience Center researchers show promise to significantly shorten the healing time and revolutionize the course of fracture treatment.
“Complex fractures are a major cause of amputation of limbs for U.S. military men and women,” said Steve Stice, a Georgia Research Alliance Eminent Scholar, animal and dairy scientist in the UGA College of Agricultural and Environmental Sciences and director of the UGA Regenerative Bioscience Center.
“For many young soldiers, their mental health becomes a real issue when they are
