Nanoscale changes in collagen are a tipoff to bone health
Date:12/22/2009

people with normal BMD can still get fractures, and abnormalities often don't show up until after a fracture has occurred. Changes in collagen, on the other hand, may be apparent earlier in the disease's progression.

To further explore the method's potential, the researchers plan to use it to study collagen fibril spacing in human patients with and without osteoporosis. U-M has filed for patent protection and is seeking a commercialization partner to help bring the technology to market.

"This project is an example of what happens if you put the right group of people together on a problem," said Banaszak Holl. Wallace, a biomedical engineer, had experience working with bone in previous research; Banaszak Holl's lab group brought expertise in surface analysis; Les contributed knowledge about bone biology and understanding of the sheep model; and coauthors Bradford Orr, director of the Applied Physics Program, and Blake Erickson, a biophysics graduate student, are skilled in data analysis.

"All these different pieces were necessary to solve the problem," Banaszak Holl said.

The research was funded by the National Institutes of Health (National Institute of Dental and Craniofacial Research and National Institute of Arthritis and Musculoskeletal and Skin Diseases).
