Comments P.409 left column 3rd paragraph: "The time to “rebuild” the granulocytic cell renewal system after hemopoietic stem cell transplantation is in the order of 10–12 days. It takes about 4 days for the granulocytes to mature after the last myelocyte division and to be released into the blood (ref 19). It takes about 6 days for cells from the myeloblast to the myelocyte stage (ref 19). Therefore, the replication of stem cells must be relatively rapid to produce enough cells to be triggered into the cellular proliferation and maturation process (ref 29). The transit time for erythropoietic cells from the earliest cell type (proerythroblast) to the release of red cells into the blood is about 5–7 days (primary sources), and the equivalent time to produce blood platelets is about 10 days in the human being (BNID 113415)."
