Michael C. Riddle, Jr., MD is a Regenerative Medicine Physician and inventor. He is an Eagle Scout and US Navy veteran. He has degrees from The George Washington University, Thomas A. Edison State College and UTMB School of Medicine. Michael has been involved with developing new technologies with regenerative medicine since 2011 and was the first to build a large lung bioreactor to grow large pig and human lungs. His team lead by Dr. Joan Nichols at UTMB was the first to grow a complete human lung using stem cells and a bioscaffold using the apparatus that Michael designed and built. Michael also designed and built an aortic valve bioreactor that is currently being used at the Mayo Clinic in Rochester Minnesota to grow live pediatric heart valves. Michael is a co-author on two articles in the journal Tissue Engineering that have been published on his team’s lung research. Working with Celling Biosciences, Michael’s current projects include the development of a transplantable live osteochondral graft made from the patient’s own cells and custom human kidneys grown in the lab for transplant. Michael is also developing new methods and devices to increase the amount of mesenchymal stem cells recovered from bone marrow aspiration.
