Safety of Autologous Bone Marrow Derived Mesenchymal Stem Cells in Erectile Dysfunction

This phase I clinical trial is designed to evaluate the safety of autologous Mesenchymal Stem Cells (MSC) injected intracavernously.

Cellgram-ED is autologous bone marrow-derived mesenchymal stem cells ex vivo expanded for approximately 30 days. Ten patients (Diabetes -associated ED; 5 patients, Postprostatectomy; 5patients) will be injected Cellgram-ED directly into the intracavernous. Patient will be evaluated the safety and potential efficacy of MSC.

Eligibility Criteria:
Inclusion Criteria:

Postprostatectomy Erectile Dysfunction
