Human cyclic neutropenia transferred by allogeneic bone marrow grafting.

Human cyclic neutropenia shows many features in common with the animal model of cyclic neutropenia in grey collie dogs. Until now, however, evidence was lacking that cyclic neutropenia in man as in the dog is caused by a defect in a transplantable hematopoietic stem cell. A patient is presented who, while undergoing bone marrow transplantation as treatment for acute lymphoblastic leukemia in re...

Bone marrow ablation followed by allogeneic marrow grafting during first complete remission of acute nonlymphocytic leukemia.

Of 33 patients who had undergone allogeneic bone marrow transplantation during first complete remission of acute nonlymphocytic leukemia, 21 patients have now been followed in continued complete remission for 6-64 mo (median greater than 18 mo) without maintenance chemotherapy. The median age of the surviving patients is 27 yr. Transplant-related complications occurring throughout the first yea...

Heterogeneous ontogeny of erythropoiesis after bone marrow ablation and allogeneic bone marrow grafting.

Thirty-two patients who underwent bone marrow transplantation for hematologic malignancies were studied for hemoglobin-F as an indicator for fetal erythropoiesis. Two different patterns of response were noted. One group of patients who had an elevated HbF level prior to marrow grafting later showed a marked reactivation of HbF synthesis, whereas the other group of patients who had normal HbF le...

Ontogeny of Erythropoiesis After Bone Marrow Ablation and Allogeneic Bone Marrow Grafting

H UMAN and several other mammalian species sequentially express different globin genes during ontogeny, or during periods of “stress,” such as hypoxemia or anemia. Hemoglobin ontogeny in humans includes three distinct phases. The “embryonic” phase predominates from the 5th to the 16th week of gestation. In this period, embryonic hemoglobin chains are and . Throughout the remainder of gestation ...

Polyclonal reconstitution of human marrow after allogeneic bone marrow transplantation.

Clonal dominance suggestive of reconstitution of marrow from small numbers of pluripotent hematopoietic stem cells has been noted in different experimental and clinical situations. Recipients of human allogeneic marrow transplants have not been previously studied to determine if clonal dominance occurs in this clinical setting. Clonal analysis of 20 allogeneic marrow transplant recipients was p...
