The PhD Program 'Regenerative Sciences’ started in October 2007. It was designed and implemented by the Cluster of Excellence REBIRTH – 'From Regenerative Biology to Reconstructive Therapy’. It aims to promote young scientists who decide to develop their career in the field of regenerative medicine, to connect research activities and foster communication within the Cluster of Excellence. The program was set up under the umbrella of the HBRS and profits thus from HBRS’ great experience in designing and implemening international graduate courses.
