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. Elektromotol'isCh angetriebene
