Project Structure & Methodology

The cmRNAbone project is structured in three main pillars aiming to:

  1. create new insights and solutions in the field of regenerative medicine (WP1–4),
  2. provide sound scientific assessment of the regenerative capacity of the proposed therapy (WP5–7), and
  3. develop regenerative application via preclinical proof of concepts and advance towards a regulatory and commercial path for a first in-human trial (WP8).

Thus, the following work packages have been defined:
