Regenerative medicine could be an attractive therapeutic alternative for treating FI. Here, we aimed to determine the safety and feasibility of autologous expanded mesenchymal stem cells derived from adipose tissue (AdMSCs) in the treatment of patients diagnosed with structural FI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>This was a randomized, multicentre, triple\u2010blinded, placebo\u2010controlled pilot study conducted at four sites in Spain with 16 adults with FI and a sphincter defect.
