This volume focuses on molecular genetic/drug manipulation affecting the biology of hematopoiesis, leukemia, and other related cancers as well as on hemoglobinopathy, aplastic anemia, pediatric oncology, growth factors in transplantation, hematologic malignancies, solid tumor chemotherapy and drug resistance, gene expression and gene transfer and on viruses and hematopoiesis. Some of the topics covered include: new information on BMT for autoimmune disease and organ transplants, new findings on gene therapy/transfer into HSC, new studies on gene transfer into primates, new information on gene transfer, scientific and clinical results of iron overload and hematopoiesis, iron and erythropoiesis and search for candidate genes, molecular diagnosis and chemotherapy, use of cord blood stem cells for transplantation, and new information on transcriptional factors regulating hematopoiesis.
