Figure 1 : The primary self renewing p-SRL line and the primary stem cell reservoir.

Between t=0 and t=96 the primary population from the Table 2 complets six cycles of asymmetric
cell division. In this way, a constant self-renewing stem cell fraction (p-SRL) with 0.8x106 D1 cells
(SRP cells) develops a quiescent stem cell reservoir of about 4.8x106 MAP cells (D21-6 cells).
