The Stem Cell Genomics Project • Objective: acquire a complete understanding of the genetic factors that: • specify stem cell identity and function; and • regulate commitment and differentiation • Rationale: • Stem cells play an essential role in the human body as they provide the starting material for every organ and tissue • Knowledge of regulatory genes acting in and on stem cells is necessary to exploit their full therapeutic potential
