Stem cells transplantation technique has high potential as a novel therapeutic strategy for ED
Date:3/15/2013

Arnhem, 11 March 2013 - Transplantation of mesenchymal stem cells cultivated on the surface of nanofibrous meshes could be a novel therapeutic strategy against post-prostatectomy erectile dysfunction (ED), conclude the authors of a study which is to be presented at the 28th Annual EAU Congress later this week.

The study was conducted by a group of Korean scientists and will be awarded 3rd prize for best abstract in non-oncology research on the opening day of the congress.

During their investigation, the group aimed to examine the differentiation of human mesenchymal stem cells cultivated on the surface of nanofibrous meshes (nano-hMSCs) into neuron-like cells and repair of erectile dysfunction using their transplantation around the injured cavernous nerve (CN) of rats.

"The objectives of the study reflect a very pertinent need in today's urology practice," said the lead author of the investigation Prof. Y.S. Song of Soonchunhyang University School of Medicine in South Korea. "Post-prostatectomy erectile dysfunction results from injury to the cavernous nerve that provides the autonomic input to erectile tissue. It is a common complication after radical prostatectomy which decreases the patient's quality of life".

"Although advances in equipment and surgical techniques reduce this complication, patients still experience erectile dysfunction after radical prostatectomy," he explained.

Treatment of phosphodiesterase 5 inhibitors shows insufficient effectiveness in the treatment of post-prostatectomy ED and it is believed that the transplantation of stem cells cultivated on the surface of nanofibrous meshes can promote cavernous neuronal regeneration and repair erectile dysfunction.

In the course of the study, the synthesised polymer was electrospun in a rotating drum to prepare nanofibrous meshes and hMSCs were prepared and confirmed. Eight week old male Sprague-Dawley rats were divided into 4 groups of 10 each
