Book Description
The monograph edited by Drs. Wunder and Henon on "Peripheral Blood Stem Cell Autogtafts" is extremely useful as well as timely. It covers the "state of the arts" with respect to the use of hemopoietic stem cells collected from the peripheral blood for the reconstitution of hematopoiesis after myeloablative therapy. If is is accepted that hematopoietic function in the mammalian organism is the result of stem cell seeding of an appropriate stromal matrix, then the use of blood derived stem cells for hematopoietic reconstitution represents the "physiological form" of the (re) establishment of a hematopoietic bone marrow. All observations to date are compatible with the assumption that stem cells migrate via the blood stream from extraembryonic hematopoietic tissue to the fetal liver to establish there a first intraembryonic site of blood cell formation and especially of stem cell replication and proliferation. This fetal liver tissue appears then to be the major source for the seeding offetal bone marrow stroma as it develops sequentially in all the bones of the skeleton - in other words during most of the entire embryonic development. There is a very high concentration of stem cells in the blood of the embryo (more than 20000 CFU-GM per ml in the 22nd week) and the stem cells in cord blood seem to be the "tail end" of a dramatic "stem cell traffic" in the embryo to establish the hemopoietic as well as lymphopoietic tissue.

Book Description
This textbook integrates basic research and clinical aspects underlying the most recent results in those malignant diseases where progress is most effective. Recent evidence shows that higher doses are better in inducing higher cure rates in hematological neoplasias, although myeloblation related to dose intensity can be a limiting factor. The toxicity can now be controlled with autologous marrow and peripheral blood progenitor cell transplantation, used with or without growth factors. The combination of high dose chemoradiotherapy followed by re-infusion of autologous stem cells constitute a dramatic advance in the treatment of refactory and relapse hematological neoplasias.

Book Description
Blood Stem Cell Transplantation conveys the excitement that accompanies the newest developments in hematopoietic stem cell transplantation. Some of the applications that stand to impact this field most significantly are based on recent advances in the biological sciences, as demonstrated by the chapters on gene therapy, on the detection of minimal residual disease using molecular techniques, and on the use of radioimmunoconjugates targeting lymphoma and leukemia-associated antigens. Others are the results of clinical observations - e.g., the association between graft-versus-host- disease (GVHD) and durable remissions that have led to creative clinical experiments such as donor leukocyte infusions (DLI). Attempts to unravel the biological events that underlie the responses seen in patients with relapsed chronic myelogenous leukemia treated with DLI are likely to provide the basis for future refinements in this clinical approach. Hopefully, improved response rates and reduced toxicity will result. The power of the immunologic response in controlling malignant disease is underscored in the chapter on post-transplant immunotherapy. The complex immunologic process that results in clinical GVHD may be dissected and engineered to provide clinical benefits that include, in addition to its antineoplastic effects, the amelioration of its clinical manifestations. Better control of GVHD with less global immunosuppression will facilitate the use of mismatched and unrelated donors. This area of investigation perfectly illustrates the continued interplay between the laboratory and the clinic. The continued cross-fertilization of ideas between immunologists, molecular biologists and clinical investigators is likely to yield important advances in this field for years to come. Possible applications of stem cell transplantation continue to grow with the identification of alternative sources of stem cells and the potential to engineer and/or expand the graft. Although the use of unrelated and mismatched donors continues to increase, the possibilities associated with umbilical cord blood transplantation are legion, especially if stem cells can be expanded ex vivo to provide grafts for full-sized adults. Using techniques in which contaminating malignant cells may be eliminated from autografts through positive selection, autologous transplantation may prove highly effective, especially when coupled with post-transplant immunotherapy. Some of these same methodologies have helped facilitate the use of autologous grafts for transplantation in patients with chronic myelogenous leukemia without allogeneic donors. Advances in the supportive care of transplant patients, including the pretransplant identification of those at risk from pulmonary complications and the use of cytokines to speed engraftment, have reduced morbidity and mortality to such a degree that it is appropriate to consider high-dose therapy and stem cell reconstitution in patients with nonmalignant diseases. The impressive advances that have occurred in transplantation for thalassemia are described by pioneers in their area of investigation. The burgeoning field of transplantation for autoimmune disorders, including its immunobiologic basis and soon-to- be-realized clinical potential, is also summarized. Continued progress in the use of high-dose therapy with stem cell rescue for the treatment of pediatric tumors, which derives in part from improved supportive care, is detailed. The sobering voice of the health care economists underscores the necessary limitations to our seemingly unbridled imagination. Cost- consciousness and financial know-how will need to be reflected in future study designs. Given the seemingly endless applications of our technology, strategies to insure its cost-effectiveness will be necessary. Continued financial support for laboratory investigation and for the clinical experiments they generate will be required if we are to go forward. Blood Stem Cell Transplantation lays the foundation for many of these future advances; it is incumbent upon us all to insure its realization.
