 My name is Michael Dettemore. I'm a professor of chemical and petroleum engineering at the University of Kansas. Our paper in biotechnology and bioengineering is focused on cartilage regeneration. The technology that we've developed is based on a plug that a surgeon could insert in lieu of the injured cartilage region to drill out the injured cartilage and put this plug in place. The plug itself that we've developed is based upon microspheres that are maybe about 220 microns in diameter. And the microspheres enable us to have a plug that can transition from one side to the other from bone promoting to cartilage promoting. This is something that a surgeon could easily implant that would be much better than other current treatment options. What makes this technology so promising in our opinion is it's focused on materials that can be integrated into the body, natural materials, raw materials that can be absorbed into the tissue as opposed to purely polymeric kind of material that needs to be degraded and removed from the site. The material that we're using is a combination of a polymer with the microspheres and the microspheres encapsulate the raw materials that we're including so the polymer is degraded and removed away and what's left behind is the raw materials or the building blocks for the tissue. The work is presented in this paper makes a lot of sense from a business perspective. It's based on raw materials that can be used as a more straightforward regulatory pathway and also as a much cheaper option. From a commercial standpoint the advantages, the cost of the materials that go into your product are cheaper than if you're using growth factors.
