Intralesional Tolerogenic Dendritic Cells in Crohn's Disease Treatment

Safety and Clinical Efficacy Evaluation of Intralesional Administration of Tolerogenic Dendritic Cells in Patients With Refractory Crohn's Disease

Intralesional Tolerogenic Dendritic Cells in Crohn's Disease Treatment.

The main objective is to evaluate the safety and clinical response of intralesional injection of Autologous peripheral blood differentiated adult dendritic cells expanded tolerogenic in patients with refractory Crohn's disease treatment.
