Blood formation is characterized by a hierarchical architecture, with a small number of stem cells at the highest level. These cells differentiate more and more until they form the huge number of blood cells in the circulating blood. Based on a simple mathematical model for this hierarchy [1], we address the dynamics of different blood disorders. The leads to analytical estimates of the survival time of mutations in the system [2,3]. For chronic myeloid leukemia, the framework allows to describe the origin, development, response to therapy, and relapse after termination of therapy [4]. The resulting dynamics consistent with the available clinical data.
