Stem-cell urological treatment was not carried out illegally

摘要

SIR - I want to express my displeasure at the News story 'Doctors accused of doing illegal stem-cell trials' (Nature 453, 6-7; 2008).rnA prospective cohort study and a prospective randomized trial of our procedure for treating urinary incontinence with autologous myoblasts and fibroblasts were filed with the ethics committee of the University of Innsbruck in February 2001.1 cannot explain why these documents are no longer intact in the committee's records. Results of the prospective randomized trial, involving 63 women, were published last year (H. Strasser et al. The Lancet 369,2179-2186; 2007).
