Dr. Bonassar,

In 2004, I presented this same idea to my classmates and colleagues, while a graduate student in Biomedical Engineering, at the University of Illinois, in Chicago. You have not developed anything new. I, and my team, did this ten years ago. Please give us the appropriate credit for something we not only conceived, but publicly presented. Significantly involved in this project were Dr. Daniel Musauski and me, Dr. Jonas Moses. This was a small group project conceived by me, and carried out -- in concert with Dr. Murauski (for our team) -- for a Cell and Tissue Engineering course, at U of IL, Chicago.

In my design, I discussed not only how to print the ear, using a bioreactor (also of my design), but how to perfuse the ear and add a skin covering (keratinocytes) to it. Thanks to Paul Stein for bringing up these two key points, in his commentary!

 

 

Respectfully,

 

 

 

Dr. Jonas Moses

Another monstrous waste of time (months!), money, and talent.  Without skin covering and a viable blood supply, what use is a white slab of gristle?  Anyone can make something just as useful in an hour with a tube of medical silicone adhesive.  Doctor Bonassar needs to tackle the much more difficult problem of nutrient delivery.  Until then, he is just an "Ordinary Cornellian".
