This book gives an updated review of the state of the art in regenerative cell therapy in the fields of cardiology, hematology, pediatrics, neurology, orthopedics and infectious diseases. The book emphasizes clinical advances as proof of concept in cell therapy based on the revolutionizing observation that regeneration can occur throughout the body even in highly differentiated organs like the heart and the neuronal system. It provides examples of breakthroughs in the clinical implementation of adult stem cell therapy.

The use of cells for the treatment of a variety of diseases is no longer a dream. Today, blood transfusion, bone marrow transplantation, the use of ex vivo cultured skin in wound healing, and peripheral stern cell transplantation, including the ex vivo expansion of hematopoietic stern cells after high-dose chemo/radiation therapy, are routine. This high standard of knowledge and skills in cell transplantation might also re sult in tackling hitherto untreatable diseases. Organ transplantation is presently the only life-saving treatment for a variety of conditions. Important findings in cell and molecular biol ogy, the identification of hematopoietic, mesenchymal and neuronal stern cells, together with breakthroughs in the methodology for isolat ing, purifying, expanding, and storing human cells could make cellular therapy an alternative to organ transplantation in certain diseases within the next decade. Placental blood may be the source of choice in isolating naive progenitor cells for allogeneic transplantation. Immunotherapy is the most hopeful strategy to date for the treat ment of tumors resistant to chemotherapy, radiation therapy, or hor mone therapy. It includes the use of tumor-infiltrating lymphocytes, ex vivo activated memory T lymphocytes, and cell-based vaccines."

Cell biology has made an appreciable impact on the evaluation of physiological and pathophysiological processes leading to a more detailed understanding of the signaling mechanisms by which cells communicate in vivo and in vitro and modify adaptively. By using cell culture models in addition to animal experiments we are now able to better define the overall and the selective potential of drugs. This book is designed to give information on the advantages and limitations and on new aspects and the meaning of cell culture models in pharmaceutical research.

As dogmas in stem cell research are losing their impact and recent findings regarding the use and cultivation of stem cells and tissue transplantation have opened up new therapeutic avenues, this Ernst Schering Research Foundation Workshop was initiated to highlight current and future approaches in this field. The only stem cells that have been used clinically for a long time is the hematopoietic stem cell as a source for bone marrow transplantation. Recent findings now indicate that hematopoietic stem cells, under certain conditions, are able to differentiate into endothelial, neural or muscle cells, providing exciting new therapeutic possibilities. They represent a future source for tissue engineering replacing defective cells or tissues and allowing diseased organs to regain their functions. Both reconstitution techniques are paving the way for the development of new therapeutic strategies, giving hope of being able to cure and not only treat patients.

Maschinelle Handwerkzeuge sind ortsbewegliche Werkzeuge, deren Arbeits- leistung durch unmittelbare elektromotorische, pneumatische oder mechanische Kraftiibertragung erfolgt. Die Anpressung an das zu bearbeitende Werkstiick und die Lenkung iri der gewiinschten Arbeitsrichtung geschieht jedoch meist von Hand, also durch menschliche Kraft. Die Vorzuge des einfachen und leichten Handwerkzeuges sind also mit der groBeren Leistungsfahigkeit einer Kraft- maschine verbunden. Die Vorteile, die sich aus dieser Verbindung erreichen lassen, ergeben zusammengefaBt eine Steigerung der Leistung des Einzelnen und damit der Wirtschaftlichkeit des Gesamtbetriebes. Die Entwicklung der Technik in den letzten J ahren, besonders auf dem Gebiet. e der wirtschaftlichen Fertigung, hat der Verwendung von maschinellen Handwerkzeugen einen ungeahntenAufschwung gegeben. In allen Betrieben dermetall-, holz-und stein- verarbeitenden Industrie, am FlieBband und in den Ausbesserungswerkstatten bietet die Verwendung der maschinellen Handwerkzeuge groBe Vorteile. DaB jede zeitspa- rende Einrichtung mithilft, dem Mangel an gelernten Fachkraften zu steuern, sei hier besonders hervorgehoben. Das vorliegende Heft der Werkstattbiicher soIl eine Ober- sicht uber den Aufbau, die Leistung und die Anwendungsgebiete dieser Handwerk- zeuge geben und dem Betriebsmann und Facharbeiter die Auswahl der maschinellen Handwerkzeuge fiir seinen Sonderzweck erleichtern. Daep nicht moglich und auch nicht erforderlich ist, im Rahmen dieses Heftes alle Konstruktionen der verschiede- nen Werkzeughersteller zu behandeln, so wird nur der grundsatzlicheAufbau beschrie- ben. Die vielen Skizzen und Bilder werden den Aufbau und die vielseitigen Verwen- dungsmoglichkeiten dieser Werkzeuge besser und leichter veranschaulichen als Worte. I.
