Transient dyserythropoiesis in repopulated human bone marrow following transplantation: an ultrastructural study

British Journal of Haematology

Abstract

Transmission electron microscopy was used to examine marrow samples from 15 patients with aplastic anaemia or acute leukaemia who had been treated with bone marrow transplantation. There were 11 allogeneic, three syngeneic and one autologous graft. The purpose was to estimate the frequency, type and extent of dyserythropoietic change. Transient dyserythropoietic features were substantiated in all cases. Nuclear changes were present in 12 cases, iron laden mitochondria (sideroachrestic phenomena) in 10 and cytoplasmic contacts and/or connections between red cell precursors in 10. Dyserythropoiesis was most conspicuous in the majority of cases between 14 and 28 d after transplantation but it may persist for over 100 d. No deficit in red cell production was noted and it is proposed that dyserythropoiesis in this circumstance is a physiological rather than a pathological phenomenon.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
