Abstract
In an elegantly written paper, Haahr and colleagues from Odense, Denmark, document the first phase 1 trial using autologous adipose-derived regenerative cells in patients with erectile dysfunction following radical prostatectomy. These results have long been awaited. In 2010, Tom Lue's group at UCSF published the first preclinical data on adipose tissue derived stem cell treatment in a rat model of cavernous nerve neuropraxia (a model that accurately and efficiently represents the pathophysiology of erectile dysfunction following nerve-sparing radical prostatectomy) (Albersen et al., 2010). Now six years later, the first clinical trial studying injection of regenerative cells derived from adipose tissue is published in EBioMedicine (Haahr et al., 2016). The advent of the first clinical data forces us as a scientific community to contemplate on whether or not we are ready for clinical translation of stem cell therapy for a non-lethal disease.
