Cornell Professor Lawrence J. Bonassar, Ph.D.

Cornell Professor Lawrence J. Bonassar presented about "3D Fabrication Technologies for Tissue Regeneration. We wrote about Bonassar's research in February when he published the concept of 3D printing a human ear.
In his presentation, Bonassar provided the crowded conference hall with an overview of the key bioprinting motivations and applications.
There are approximately 5 million surgeries per year in the US to replace damaged tissues. This is a huge market opportunity for synthetic, bioprinted implants. His team is already looking at research such as replacing spinal discs, demonstrated in rats and dogs, or growing organic tissue like a human ear.
During the Q&A, Bonassar was asked: "This is great research, but is there a way to accelerate it into the marketplace? Bonassar immediately responded, "Yes, money.

medical illustration of Lawrence Bonassar of Cornell University and colleagues have used 3-D photography of living human ears to create 3-D-printed ear molds. The molds are filled with a gel that includes cartilage cells from calves suspended in collagen, which hold the ear's shape as a guide while the cells grow their own newly synthesized extracellular matrix. Anthony Atala and colleagues are designing a 3-D printer that scans wounds and deposits layers of stem cell-filled fibrinogen and collagen directly onto them.

A research group led by Lawrence Bonassar, PhD, professor of biomedical engineering at Cornell University, and graduate student Edward Bonnevie, MS, has discovered that another molecule, lubricin, helps anchor hyaluronic acid at the tissue surface, which, in turn, helps to move cartilage into a low-friction regime.

"The implication of this finding is that the efficacy of hyaluronic acid treatment might depend on how much lubricin is in the joint at the time of injection, which could explain why clinical trials of hyaluronic acid have such variable outcomes and may also suggest new formulations of hyaluronic acid that might be even more effective in the clinic," said Dr. Bonassar.
The study, published online November 24 in the journal PLOS ONE, examined how multiple formulations of hyaluronic acid lubricated cartilage. The researchers found that all hyaluronic acid formulations worked by a similar mechanism, "one that is very similar to how a car hydroplanes on a wet road," said Dr. Bonassar.
Essentially, the viscous hyaluronic acid solutions form pressurized films that lower the friction coefficient of cartilage, particularly at higher sliding speeds.
"For many years, people doubted that this mechanism could happen in cartilage because the tissue is both flexible and porous. In this paper, we show definitively that cartilage can move to this low-friction domain in the presence of highly viscous hyaluronic acid solutions," Dr. Bonassar said.
