Book Description
This is the first atlas dedicated to illustrating the cellular and molecular mechanisms that underlie the unique features of human hematopoiesis during embryonic, fetal, and neonatal developments. This state-of-the-art atlas is published more than thirty years after the legendary ‘Atlas of Human Hemopoietic Development’ by Kelemen, Calvo and Fliedner. After presenting the principles of developmental hematopoiesis, the atlas focuses on lineage-specific processes. The unique material of the previous atlas by Kelemen et al. is used to illustrate the histologic features of human embryonic and fetal hematopoiesis. Findings from animal studies are included to provide an up-to-date description of cellular and molecular mechanisms. Including approx. 300 full-color figures Plus DVD with additional material. Molecular mechanisms are schematically depicted in figures or line drawings, presented side-by-side to the referred microscopies. Together, these present a clear graphic depiction of the changes that occur during the normal development of the human hematopoietic system, and their implications to hematologic disorders with onset during fetal life or infancy. Of particular interest to clinicians: Molecular and clinical aspects of the most frequent hematologic disorders in fetuses and neonates Reference values for different hematological parameters during fetal and neonatal development. This atlas provides a unique source of information for clinicians and researchers working in the fields of developmental biology, fetal medicine, perinatal medicine, neonatology, pediatrics, and hematology.

Book Description
During the past 20 years, celJ biology has made immense strides which have completely transformed the time-honored morphological hematology of yesterday. This progress is primarily due to the introduction of new techniques which allow functional rather than anatomic studies: labeling techniques have made possible the study of celJ kinetics from birth to death of a celJ: culture techniques (both in vivo and in vitro) have made it possible to establish the progeny of certain stern celJs, their growth poten tiaL and the mechanisms of their regulation. The results have been so impressive and have so aroused the enthusiasm 01' young hematologists that it has become fashionable in so me quarters to consider the microscope an "extinct instrument" and morphology littlc more than an outmoded (if agreeable) pastime of little scientific interest. One of the consequences is the wish of some investigators to study cytology without the aid of their eyes. The present book makes us realize once more that morphology is the science of structure and shape and that its aim is not to colJect pictures but to understand them. It is true that microscopic observation, even when made with the electron microscope, cannot by itself answer some basic questions of celJ biology. However, the hematologist who uses only a single technique is like a person who would describe the world from the point of view of a single sensory organ and would refuse the aid of the others.

Book Description
Hematopoiesis, or the process of blood formation, has been extensively studied at both basic and clinical levels. Human diseases such as thalassemia, immunodeficiency, and leukemia represent defects in this process. Approaches to treat these disorders have required a basic understanding of the biology of blood cells. For instance, hemapoietic stem cell replacement or bone marrow transplantation has been used to ameliorate disease. This volume focuses on hematopoiesis at a cellular and molecular level, and establishes the basis for clinical manipulation of hematopoietic cells for therapeutic benefit. In Part I, the cellular characteristics of progenitors and stem cells are explored. Emphasis is placed on purification of stem cells and both in vitro and in vivo assays. The regulation of normal and leukemis stem cells is illustrated. An excellent discussion of potential use of these cells for gene therapy concludes this section. Hemapoiesis is easily studied during embryogenesis. Part II develops the concept of the waves of hemapoiesis during development. Comparative hematology is making a major comeback as a field in the 1990's. One hope is that general principles of hematopoiesis will be established by studying many models and systems. Part III delves into critical factors that regulate hematopoiesis, including both intracellular and extracellular signals. Part IV and V describe lineage programs for myeloid and lymphoid lineages. These chapters are meant to be illustrative of the different cell fates, but are not exhaustive. Part VI examines the genetics of hematopoisis, particularly in animal models. The hematopoietic system is in constant contact with stromal cells and endothelial cells during development and in the adult. Evidence suggests that endothelial cells and blood cells may arise from a common progenitor, the hemangioblast. Part VII and VIII discuss the stromal and endothelial cells with the emphasis on their interaction with hematopoietic cells.

Book Description
Although much is known with respect to blood cell formation and function, many new concepts in the areas of the regulation of hematopoietic stem cell commitment and the subsequent survival, proliferation, and differentiation of progenitors have been elucidated in the last five years. Our understanding of the microenvironment where stem cells reside and commit to distinct blood types (the niche) has grown significantly in recent years. Furthermore, blood cells have been used as the key model system to study microRNA function and the role of microRNAs in the transformation of normal cells into cancer cells. The current volume Molecular Basis of Hematopoiesis, edited by Amittha Wickrema & Barbara Kee, provides the most recent developments in the area in addition to a chapter on the utilization of basic science knowledge for the treatment of blood diseases. Each chapter in this book has been written and edited by faculty in major academic and research institutions around the world, who are pushing the frontiers of research in this important area.

Book Description
In the summer of 1988, my developmental biology professor announced to the class that hematopoietic stem cells (HSCs) had finally been purified. Somehow, I never forgot the professor’s words. When I started working in Dr. Irv Weissman’s labo- tory at Stanford as a postdoctoral fellow, I realized that the findings mentioned by the professor were from Weissman’s laboratory and had been published in a 1988 edition of the journal Science. It has been over 20 years since the publication of that seminal paper, and since then tremendous advances in understanding the biology and maturation of HSCs, namely the process of hematopoiesis, which includes lymphocyte development, have been made. These discoveries were made possible in part by advancements in technology. For example, recent availability of user friendly fluorescence activated cell sorting (FACS) machines and monoclonal an- bodies with a variety of fluorescent labels has allowed more scientists to sort and analyze rare populations in the bone marrow, such as HSCs. All classes of hematopoietic cells are derived from HSCs. Stem cell biology draws enormous attention not only from scientists, but also from ordinary people because of the tremendous potential for development of new therapeutic application to diseases that currently lack any type of effective therapy. Thus, this type of “regenerative medicine” is a relatively new and attractive field in both basic science and clinical medicine.

Book Description
The blood system is organized as a developmental hierarchy in which rare hematopoietic stem cells (HSCs) generate large numbers of immature progenitors and differentiated mature blood cells. In this process, at least ten distict lineages are specified from multipotent stem cells, however the cellular and molecular organization of the hematopoietic hierarchy is a topic of intense investigation. While much has been learned from mouse models, there is also an appreciation for species-specific differences and the need for human studies. Blood lineages have been traditionally grouped into myeloid and lymphoid branches, and the long-standing dogma has been that the separation between these branches is the earliest event in fate specification. However, recent murine studies indicate that the progeny of initial specification retain the more ancestral myeloid potential. By contrast, much less is known about the progenitor hierarchy in human hematopoiesis. To dissect human hematopoiesis, we developed a novel sorting scheme to isolate human stem and progenitor cells from neonatal cord blood and adult bone marrow. As few as one in five single sorted HSCs efficiently repopulated immunodeficient mice enabling interrogation of homogeneous human stem cells. By analyzing the developmental potential of sorted progenitors at a single-cell level we showed that earliest human lymphoid progenitors (termed LMPs) possess myelo-monocytic potential. In addition to B-, T-, and natural killer cells, LMPs gave rise to dendritic cells and macrophages indicating that these closely related myeloid lineages also remain entangled in lymphoid development. These studies provide systematic insight into the organization of the human hematopoietic hierarchy, which provides the basis for detailed genetic analysis of molecular regulation in defined cell populations. In a pilot study, we investigated the role of a zinc finger transcription factor (ZNF145), PLZF, in myeloid development. We found that PLZF restrained proliferation and differentiation of myeloid progenitors and maintained the progenitor pool. Induction of ERK1/2 by myeloid cytokines, reflective of a stress response, leads to nuclear export and inactivation of PLZF, which augments mature cell production. Thus, negative regulators of differentiation can serve to maintain developmental systems in a primed state, so that their inactivation by extrinsic signals can induce proliferation and differentiation to rapidly satisfy increased demand for mature cells. Taken together, these studies advance our understanding of the cellular and molecular architecture of human hematopoiesis.
