The population doubling times (PDTs) of hACL-SCs and hMCL-SCs. The PDT of hACL-SCs was markedly greater than that of hMCL-SCs, indicating that hACL-SCs proliferated more slowly than hMCL-SCs. The PDT results were obtained from passage 1 to passage 2 for both ACL-SCs and MCL-SCs from six donors (see Table 1).
