Although cell fusion is an omnipresent process in life, to date considerably less is still known about the mechanisms and the molecules being involved in this biological phenomenon in higher organisms. In Cell Fusion in Health and Disease Vol 1 & Vol 2 leading experts will present up-to-date overviews about cell fusion in physiological and patho-physiological processes, which further covers the current knowledge about cell fusion-mediating molecules. Volume 1 deals with Cell Fusion in Health and will cover aspects of cell fusion in fertilization, placentation, in C. elegans, in skeletal muscle development and tissue repair, and the use of cell fusion for cellular reprogramming and cancer vaccine development. Volume 2 focuses on Cell Fusion in Disease with a particular emphasis on the role of cell fusion in cancer development and progression. Thus, Cell Fusion in Health and Disease Vol 1 & Vol 2 represents a state-of-the-art work for researchers, physicians or professionals being interested in the biological phenomenon of cell fusion and beyond.

Stem Cell Biology in Health and Disease presents an up-to-date overview about the dual role of stem cells in health and disease. The Editors have drawn together an international team of experts providing chapters which, in this fully-illustrated volume, discuss:

- the controversial debate on the great expectations concerning stem cell based regeneration therapies raised by the pluripotency of various stem cells.
- the advantages and concerns about embryonic stem cells (ES cells), induced pluripotent stem cells (iPS cells) and adult stem cells, such as bone marrow-derived stem cells (BMDCs).
- the type of stem cells, which has become of interest in the past decade, namely so-called cancer stem cells (CSCs). CSCs are now in the focus of cancer research since the eradication of tumour initiating cells would raise the changes of definitely cure cancer.

Professor Dittmar and Professor Zanker have edited a must-read book for researchers and professionals working in the field of regenerative medicine and/or cancer."

This book summarizes the latest findings about the role of cancer stem cells (CSCs) in cancer biology and how this knowledge could be used for novel anticancer therapies. It provides an overview of CSCs in selected malignancies with particular emphasis on hematopoietic neoplasias. It then reviews the role of CSCs in metastasis formation and initiation of cancer relapses. It also examines the dark site of cancer therapy such as conventional cancer therapies that may lead to the origin of recurrence CSCs. Finally, it supplies a brief overview of current concepts that may allow for a selective eradication of CSCs.

Thomas Dittmar untersucht das Einsatzpotenzial bankinterner Markte bei der Allokation von haftendem Eigenkapital und Ausfallrisikopositionen."

Today, cancer is the second most prevalent cause of death, after heart disease, in the industrialised world. Till now, and despite promising results in cancer research, the primary cause of death in cancer is still 1: the formation of metastases at distant organs sites, 2: the presence of cancer cells that are resistant to current cancer therapies (chemotherapy/radiation) and which cause cancer relapse. Within the past three years it became evident that also solid tumour tissues contain a kind of stem cells, so called cancer cells. These cancer stem cells have been described as chemo-radiation therapy resistant tumour initiating cells. The purpose of this book is to summarise the latest findings about the role of stem cells in cancer.
