I do not know the origin of the phrase "...a gift from the devil's grandmother." I first read it in Einstein's letters to Schrödinger. Einstein employed the phrase to describe his fear of failing to find a unified theory of relativity and quantum physics. The problem appeared unsolvable. A similar gift in the field of clinical trial research in wound healing appeared on my doorstep recently. I started my research career conducting double-blinded pharmaceutical trials. After a string of failures, I convinced myself that advanced therapy in chronic wounds was doomed; however, cellular- and/or tissue-based products (CTPs) entered the market with encouraging results, brightening my spirits. To date, our cooperative group of investigators has published more than a dozen trials demonstrating the efficacy of CTPs in the treatment of diabetic and venous ulcers.
