Bone marrow is currently regarded as the most appropriate source of stem cells for patients with acute myeloid leukemia (AML) undergoing autologous transplants. A total of 55 adult patients with AML in first complete remission receiving autologous bone marrow-derived stem cell (BMSC) transplantation (BMSCT) were analyzed to determine factors affecting the rate of neutrophil recovery. All patients were treated with standard induction and three to four courses of consolidation chemotherapy and, after collection of BMSC, conditioned with BuCy2. The median time to neutrophil reconstitution was 30 (10-62) days and was delayed in 24 patients. Neutrophil recovery was faster in patients who had received granulocyte-macrophage progenitors (CFU-GM) dose >23.5 x 10(4)/kg, CD34(+) cells >3.2 x 10(6)/kg, and mononuclear cells (MNCs) >3 x 10(8)/kg. The speed of neutrophil recovery correlated with the number of transplanted CFU-GM progenitors (P = .0077) and MNCs (P = .0015). CFU-GM progenitors dose was the only factor close to significance in univariate analysis of neutrophil engraftment. Probability for neutrophil recovery was higher in patients transplanted with a higher dose of MNCs. These data suggested that the content of CFU-GM progenitors and MNCs within the bone marrow graft was the most important factor for the quality of neutrophil recovery after autologous BMSCT in AML patients.

UI	MeSH Term	Description	Entries
D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D006650	Histocompatibility Testing	Identification of the major histocompatibility antigens of transplant DONORS and potential recipients, usually by serological tests. Donor and recipient pairs should be of identical ABO blood group, and in addition should be matched as closely as possible for HISTOCOMPATIBILITY ANTIGENS in order to minimize the likelihood of allograft rejection.

D006680	HLA Antigens	Antigens determined by leukocyte loci found on chromosome 6, the major histocompatibility loci in humans. They are polypeptides or glycoproteins found on most nucleated cells and platelets, determine tissue types for transplantation, and are associated with certain diseases.
